Canon’s new flagship EOS-1D X Mark III review

   In early 2020, Canon launched the latest flagship SLR camera of the 1D series—EOS-1D X Mark III. This camera has been receiving attention since its development and release. Condensed Canon’s top design and technology. Canon 1D series has always been the main photographic equipment in professional photography fields such as sports, news, etc., frequently appearing in various competitions and press conferences at home and abroad. What I want to review and introduce today is the main equipment that professional photographers will use for a long time in the future-Canon EOS-1D X Mark III.

Canon's new flagship EOS-1D X Mark III review

   From EOS-1D X in 2011 to EOS in 2016 -1D X Mark II, and then to the current EOS-1D X Mark III, it is obvious that the upgrades of this series are released according to the year of the Olympic Games. The reason why it is called the top is that the EOS-1D X Mark III in 2020 has transformed into a real universal camera. This “universal” is manifested in both continuous shooting speed and video shooting. In the following, we will show you what a truly top-level flagship SLR is through the “Appearance Show”, “Image Quality Evaluation”, “Video Evaluation” and other aspects.

  1. Canon EOS-1D X Mark III appearance display: professional design, invaluable

   In fact, at the beginning of the year, Canon released EOS-1D X Mark III, S Jun also arrived at the scene and tried the real machine. But because the trial time was not too long, many performance details could not be shared with you in the first place. Now that I can play with this camera again, I am full of excitement.

Canon's new flagship EOS-1D X Mark III review

   What catches everyone’s eyes is that the body cap is not there yet The EOS-1D X Mark III body body removed. The magnesium alloy body is extremely resistant to impact, the electromagnetic shielding effect is extremely good, and the weight is reduced to 1440g. This appearance may have such doubts for friends who have less contact-why must this camera be “bundled” with a vertical handle? In fact, the answer is very simple. Both horizontal and vertical images must be taken into account in sports photography. Unlike ordinary players, they also think about the weight of the vertical handle and how much extra to buy. Indeed, professional photographers do not need to consider these, they only focus on how to take a good photo.

Canon's new flagship EOS-1D X Mark III review

  Canon EOS- 1D X Mark III uses Canon’s newly developed 20.1 million pixel full-frame sensor, as well as a newly developed high-detail low-pass filter. The ability to reduce moiré and suppress noise has been greatly improved compared with the previous generation. The fineness of the image will be higher.

Canon's new flagship EOS-1D X Mark III review

   Canon EOS- The most “horrible” part of 1D X Mark III is that it supports continuous shooting with a maximum of 16 frames per second with a mechanical shutter and a maximum of 20 frames per second with an electronic shutter. It wins at speed and is a real instant catcher.

Canon's new flagship EOS-1D X Mark III review

  This continuous shooting What is the speed level? It is a realm of “non-other”, this is the world’s fastest continuous shooting full-frame SLR camera. In the real-time display mode, 20 frames per second is also on par with the flagship model next door, ranking first together. Why can it have such a powerful continuous shooting performance? The reason is that the new DIGIC X digital image processor is used, which can realize more powerful high-speed data processing and improve the ability of image noise reduction.

Canon's new flagship EOS-1D X Mark III review

  New DIGIC X The digital image processor brings better low and high sense of camera. In terms of native ISO, Canon EOS-1D X Mark III supports ISO 100-102400, and scalability supports ISO 50 and ISO 819200. And a new “clarity” function has been added, let’s talk about the detailed experience below.

Canon's new flagship EOS-1D X Mark III review

   Let’s see The top of the camera, the left side of the top should be one of the biggest differences from consumer-grade SLR cameras, because it is neither a dial design nor a dial lock setting, but a simple three buttons. Novice players can hardly understand these three buttons, but for professional players, this is the best operation logic configuration.

Canon's new flagship EOS-1D X Mark III review

   three buttons Respectively correspond to “MODE mode selection”, “DRIVE focus drive mode”, “exposure compensation metering mode”.

Canon's new flagship EOS-1D X Mark III review

   After pressing the button, you can switch back and forth with the front and back dials Modes and parameters. Seriously, after using this mode of control, I even forgot other SLR operation modes. But if the consumer-grade SLR adopts an over-professional control mode, it will make the threshold for playing photography even higher. This is probably the biggest difference between professional and consumer.

  By the way, due to the use of carbon fiber-based composite materials to make camera shutter blades, and surface treatment to reduce friction, EOS-1D X Mark III has a shutter life of about 500,000 times.

Canon's new flagship EOS-1D X Mark III review

   The back of Canon EOS-1D X Mark III is still the same as before Super professional, most people will be a little confused to see such dense keys, but you will find that the key layout is extremely reasonable. The back LCD screen is a full-touch 3.2-inch LCD screen with the most comprehensive touch operations, including two-finger zoom, playback and switching photos. In response to feedback from professional eco-photography users that it is not easy to distinguish buttons such as “Playback” and “Menu” in the dark night, Canon has designed a backlight feature for the buttons behind the EOS-1D X Mark III.

Canon's new flagship EOS-1D X Mark III review

   as shown above, By default, these 7 buttons will start to glow when the menu button is pressed, and the light is relatively weak, which will not affect the battery life at all. During the evaluation and shooting, Mr. S used to shoot at night. Indeed, the backlight design is very subtle, and the false touch rate is minimized. You don’t have to worry about using the phone to turn on the LED for lighting because you are not familiar with the camera.

Canon's new flagship EOS-1D X Mark III review

   The main operation of the camera is done by the joystick and the dial , Menu selection and focus or focus area selection can use these two main components. The camera switch and key lock at the bottom are also different from ordinary SLR cameras. It is set in the middle of the back of the camera. All this is to ensure that the photographer can work more focused.

Canon's new flagship EOS-1D X Mark III review

   lower left on the back of the machine There is a small LCD screen, here is mainly to display the memory card usage. It may not be necessary for ordinary users, but for news reporters and sports photographers, it is a very bad thing to not be able to confirm the status of the memory card in real time. Therefore, in order to make the photographer more at ease, the flagship SLR must be equipped with an auxiliary LCD screen. Its lighting method is the same as that of the shoulder screen lighting, both of which light up simultaneously.

Canon's new flagship EOS-1D X Mark III review

   while facing upward At a glance, you will find another brand new design of EOS-1D X Mark III, an enhanced AF-ON button. This button is called the “smart controller”, and Mr. S was really amazed when he used it for the first time-because it can use the principle of touch to select the focus point.

Canon's new flagship EOS-1D X Mark III review

  Intelligent The controller can adjust the sensitivity to make the focus move faster or slower.

The smart controller is better than the joystick. The sensitivity of the finger sliding can be adjusted according to the photographer’s habits, which can be very effective Improve the efficiency of focus point selection. Regarding the smart controller, there are two upper and lower sides on the body, you can choose to open all, close all or just close the vertical. The intelligent controller can be said to be a new combination of modernization and specialization.

Canon's new flagship EOS-1D X Mark III review

   The side of the Canon EOS-1D X Mark III looks like Very domineering, the number of interfaces alone has reached 8!

Canon's new flagship EOS-1D X Mark III review

  Because sports reporters need to shoot and transmit immediately, news timeliness requirements The first time the film is published, the Ethernet wired LAN interface is very important. Both USB-Type C and HDMI interfaces are to ensure data transmission and high-definition output.

Canon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III review

  Another row of interfaces, there is a very important WFT-E9C access network accessory interface, this accessory’s The special feature is that the camera supports IEEE 802.11ac 2*2 MIMO high-speed wireless communication. The camera itself supports IEEE 802.11b/g/n wireless transmission, and the built-in Wi-Fi supports automatic image transmission and FTP server function. The wireless transmission does not affect the stability of the body as previously said. Even Bluetooth 4.2 is also added Up. The remaining microphone, headset, and shutter release ports are all important ports for video shooting, and also correspond to this generation of deeply enhanced video functions. Regarding the video, we will introduce it in detail below.

Canon's new flagship EOS-1D X Mark III review

   Canon EOS- 1D X Mark III has been replaced with CFexpress in terms of memory card, which is currently the most powerful memory card. For photographers shooting sports and news, the slightest mistake in touching is not allowed during shooting, so to open the memory card compartment, you need to turn on the special switch first.

Canon's new flagship EOS-1D X Mark III review

   After the card compartment is opened, we see that there are 1 card and 2 Card, there is a CFexpress next to it. Although the performance of this memory card is excellent, the price is also quite amazing. The 512GB CFexpress directly costs about 4999 yuan.

Canon's new flagship EOS-1D X Mark III review

   average 10 yuan 1GB capacity, but can meet the writing speed of 1400MB/s and the reading speed of 1700MB/s. Seeing this, it suddenly dawned on me that this camera supports crazy continuous shooting of up to 20 frames per second in JPEG+RAW, and 5.5K 12-bit RAW video shooting that I haven’t mentioned yet. The CFexpress is behind it.

Canon's new flagship EOS-1D X Mark III review

   just like just now As mentioned, the battery compartment and the memory card compartment are equally important. You need to turn on this special switch before viewing.

Canon's new flagship EOS-1D X Mark III review

   EOS-1D X Mark III uses the model LP- The battery life of the E19 can reach 2850 frames when shooting in the optical viewfinder mode, while the battery life can reach 610 frames in the real-time display mode. It has to be said that this endurance performance is currently top-level.

Canon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III review

   Canon EOS-1D X Mark III not only has an extremely sturdy magnesium alloy body, but also has a whole body waterproof and drip-proof Dust treatment, even in harsh environments such as rain, snow, wind and sand, will not be affected at all. Next, let’s enter the wonderful performance evaluation session!

  Second, Canon EOS-1D X Mark III noise evaluation test: noise reduction is further

   Canon EOS-1D X Mark II uses The dual DIGIC 6+ digital image processor was limited by technology at the time. Although the machine equipped with “dual cores” guaranteed performance, it also added a lot of burden on power consumption. The EOS-1D X Mark III uses a brand-new DIGIC X processor, which can ensure high-speed processing of a large number of continuous shots, while also bringing better purity to the photos. The following image quality test was taken with the same exposure under different ISO values, and two screenshots were taken and displayed at 100% magnification.

Canon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III review

  ISO 50 is a special low-sense extension, sacrificing latitude to obtain stronger refinement High performance, I think it is a very good choice when there is no big light ratio. EOS-1D X Mark III’s native ISO range is 100-102400. If you exclude the extension value, I think the noise performance up to ISO 12800 is still acceptable. To my surprise, until the native ISO maximum of 102400, we can still vaguely distinguish the micro-digits in screenshot 1, and the color accuracy of screenshot 2 is acceptable. I think the software can reduce noise in extreme situations, even ISO 102400 is still usable! The last three expansion values ​​are estimated to be used as a last resort, and the image quality loss has been quite serious.

   Third, Canon EOS-1D X Mark III continuous shooting combat: moving and reliable

   Canon EOS-1D X Mark III target positioning It is a professional user group, and the top continuous shooting speed can help them capture every wonderful moment. Before the actual combat, first introduce the EOS-1D X Mark III focusing system: Canon has newly developed a new AF system with 191 high-resolution AF points, which also contains 155 cross-type AF points. The number of focus points is more than three times that of EOS-1D X Mark II.

Canon's new flagship EOS-1D X Mark III review

  EOS-1D X Mark III’s new 191-point autofocus system

   To be precise, the detection ability, focusing speed and accuracy in vertical, horizontal and even diagonal directions are greatly enhanced compared to the previous generation machine. In addition, the focus brightness range of the center focus point has been increased to -4EV-21EV, enabling precise focusing in extreme dark and light.

   In the real-time display mode, the mature full-pixel CMOS AF brings a high-speed and smooth focusing experience, with a maximum focus coverage of 90%*100%, and a total of 3869 focus points . Regardless of the mode, EOS-1D X Mark III is the camera with the most powerful focusing system.

   Shooting birds is a subject that tests the camera very highly. It mainly tests the focus system and continuous shooting performance of the camera. Let’s look at the GIF results first.

Canon's new flagship EOS-1D X Mark III review

  夜A total of 80 frames of animated pictures of heron carrying branches

  The biggest feature of this group of animated pictures, even after the night heron flies into the woods, the focus on it is still Clear, fully demonstrates that the camera’s focus tracking performance is extremely strong, and will not change due to the background switching of the subject. To be honest, if I switch to a normal camera, I believe that the focus will be lost long ago after entering the woods. I directly selected 6 frames at random to let everyone see the clear big picture animation changes before and after the night heron enters the woods——

Canon's new flagship EOS-1D X Mark III review

   S Jun was photographing night herons on a sunny afternoon. But because it is an instant shot of a speed theme, a very high shutter speed must be guaranteed. I set the ISO value to ISO 3200, and the shutter directly soared to a maximum of 1/8000 second, and this time I used Canon EOS-1D X Mark III. Newly added Case A mode in artificial intelligence servo autofocus to shoot.

Canon's new flagship EOS-1D X Mark III review

   ecological photography and It is not as boring as everyone thinks, it is very difficult, and it also tests people’s concentration and the durability of the camera’s continuous work. I wonder if you find anything when you look at the animation above? Before the night heron enters the woods, the branches are in the shape of “匚”. But after entering the woods, the branches became “Factory”.

Canon's new flagship EOS-1D X Mark III review

   precisely because of the EOS which can shoot up to 20 frames per second -1D X Mark III, we can tell Yelu that you dropped a branch in the file numbered “_63I3536”.

Canon's new flagship EOS-1D X Mark III review

   The moment when the night heron dropped a branch during the transportation

  High-speed continuous shooting can not only get the wonderful photos of the moment we want, but also get some surprises and emotions. This is the charm of photography.

   In addition, I also tried to take advantage of the opening of the training ground downstairs in the evening to shoot a football match. When shooting sports games, Canon has its unique skill, that is, full-pixel CMOS AF technology that supports face detection and eye detection and supports touch focus operation. First, I will show you a dribble shot in real-time display mode.

Canon's new flagship EOS-1D X Mark III review

  再Every moment of the athlete’s movement is confirmed once, and it can be clearly captured under 20 frames per second continuous shooting!

Canon's new flagship EOS-1D X Mark III review

   but I’m more What I want to say is that even if someone else blocks the subject during the tracking and continuous shooting, the focus can still be locked on the subject, which is enough to show the unparalleled tracking performance of the EOS-1D X Mark III.

Canon's new flagship EOS-1D X Mark III review

  EOS-1D X Mark III with 400,000 pixels RGB+IR The metering sensor, coupled with the DIGIC X image processor and a new algorithm can achieve accurate detection of the face and eyes of the person, and the continuous shooting can be accurately focused in one go.

   Fourth, Canon EOS-1D X Mark III new features: “Sharpness” and HEIF

   Definition selection is a new feature added to EOS-1D X Mark III. The resolution options are -4 and +4 extremes, and 0 is the original image. Generally speaking, -4 will give the image a hazy feeling, which is particularly soft in portraits; +4 will enhance the edge contrast of image details, which is particularly hard in the scenery. It just happens that the whole country can see a big round moon in mid-April. How about taking a picture of the moon?

Canon's new flagship EOS-1D X Mark III review

   I have to Praise again for the excellent auxiliary performance of the backlight button when shooting at night!

Canon's new flagship EOS-1D X Mark III review

  EOS-1D X Mark III shooting moon definition setting animation

   We directly use EOS-1D X Mark III with EF 100-400mm f/4.5-5.6L IS II USM , The exposure parameters are ISO 3200, the aperture is F/6.3, the shutter is 1/125, and the original JPEG is straight out. The moon was not particularly bright that night, or even a bit dim, but with the excellent imaging of the EOS-1D X Mark III, high image quality can be guaranteed even with high sensitivity.

Canon's new flagship EOS-1D X Mark III review

   this time , It highlights the importance of clarity +4. Obviously, it is not simply sharpening the overall image, but only intensifying the edges of the details of the image, which can be seen in particular by craters on the moon. At this time +4 will be better than 0 imaging. When will -4 be used? As long as you want to express soft themes, such as flowers and other themes.

Canon's new flagship EOS-1D X Mark III review

  Sharpness- 4It is very effective when expressing soft subjects.

   At this time, another new camera feature is introduced. Why don’t we use the new HEIF to shoot? The reason is that shooting the moon and flowers is not in the case of large light ratio. The new HEIF has a higher dynamic range, which is especially suitable for taking photos of subjects with a large light ratio. HEIF image format, the full name of High Efficiency Image File Format, it is a 10-bit color depth image format based on HEVC encoding technology, the biggest feature is that it has rich colors and higher latitude, and can be nearly 50% less than JPEG The volume capacity.

   To shoot HEIF, you only need to turn on the HDR PQ option of EOS-1D X Mark III.

Canon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III review

   There are two options of mid-tone priority and highlight priority. There are also HDR VA1 and HDR VA2 options during playback .

Canon's new flagship EOS-1D X Mark III review

   and HEIF and The quality can be set as well as JPEG. We choose midtones to experiment first. Shoot the JPEG and HEIF of the same scene with the same exposure parameters.

   We use Canon Digital Photo Professional 4 to turn on the captured JPEG and HEIF, and turn on the highlight and shadow warnings.

Canon's new flagship EOS-1D X Mark III review

   do this step The purpose is to more intuitively see the difference between JPEG and HEIF in expressing highlights and shadows. The results are as follows:

Canon's new flagship EOS-1D X Mark III review

HEIF no highlight shadow warning

Canon's new flagship EOS-1D X Mark III review

  JPEG has highlight shadow warning

  From the histogram, we can see the huge difference in color distribution between the two.

Canon's new flagship EOS-1D X Mark III review

  JPEG on both sides extreme More distribution

Canon's new flagship EOS-1D X Mark III review

There is almost no distribution on both sides of HEIF

   It’s okay to not understand the histogram. Let’s zoom in on the highlights and shadows for everyone to see:

Canon's new flagship EOS-1D X Mark III review

  JPEG highlights

Canon's new flagship EOS-1D X Mark III review

  HEIF highlight part

   Actually, the effect is not obvious to the naked eye. If you want the effect to be more obvious, Canon recommends using the camera Prioritize the highlight tone of the camera. But in order to verify the difference, we can display it with color blocks.

Canon's new flagship EOS-1D X Mark III review

  JPEG has red Highlight warning

Canon's new flagship EOS-1D X Mark III review

  HEIF No red highlight warning

   Let’s take a look at the shaded part:

Canon's new flagship EOS-1D X Mark III review

   Okay, in fact, I just want to explain that HEIF is really a very forward-looking file format, it is just one All-round spike JPEG format! But we know that this format has been introduced for many years, but it is really difficult to kill JPEG. It’s like Apple has already promoted HEIF vigorously when the iPhone 7 was launched, but knows that it will not be possible to replace JPEG immediately, and it will automatically convert to JPEG during file transfer in the machine.

Canon's new flagship EOS-1D X Mark III review

  EOS-1D The same is true for X Mark III. We can’t see HEIF on all major platforms, but we can convert it to a more beautiful JPEG in the camera! From this we can see that Canon is very considerate.

   is like we all know that USB Type-C has high positive and negative insertion efficiency, and it can completely kill USB Type-A and USB Type-B. However, this is true It’s not a matter of overnight. But it doesn’t matter, as long as it is a good thing, it is worth promoting. After all, EOS-1D X Mark III is really likely to be used for 10 years! Until then, we will not believe that HEIF has not yet been popularized.

   5. Canon EOS-1D X Mark III video: 5.5K 12-bit RAW unparalleled in the world

   Canon EOS-1D X Mark III To be a top-level flagship SLR, it is natural to have a brother’s style in video specifications. We have never seen a 5.5K 12-bit RAW video format on a single SLR camera. The EOS-1D X Mark III is Canon’s first and the world’s first.

Canon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III review

  Canon DDP4.0 software opens the RAW video, you can nondestructively modify the white balance photo style and other details

What is the concept of   5.5K 12-bit RAW video? To put it simply, the super-sampling 4K video is shot through the almost full-pixel reading of the sensor, which can get finer picture details than general 4K video. But because S has no professional non-linear editing application software, he can only use DDP4.0 to open this RAW video.

  DDP4.0 also supports opening the video while exporting a single frame static image. I captured 100% enlarged details:

Canon's new flagship EOS-1D X Mark III review

   is very awkward and polite to say that from the 5.5K super-sampled 4K video of Canon EOS-1D X Mark III, I can see that the air conditioner outside the crane master is a beautiful air conditioner. Such a high-definition video is also the first time Mr. S has seen it in his imaging career.

Canon's new flagship EOS-1D X Mark III review

  DDP4.0 Freely export RAW video single frame image

Canon's new flagship EOS-1D X Mark III review

  5.5K RAW video single frame image

  5.5K RAW video itself has extremely high dynamic range, even if Canon Log is not enabled when shooting, you You can also choose the photo style to directly define the video color. But if you choose Canon Log, you can no longer choose a photo style. By the way, taking into account the workflow of professional photographers, Canon EOS-1D X Mark III supports simultaneous recording of 5.5K RAW movies and uncut 4K DCI Canon Log movies.

Canon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III review

   It should be noted that when the camera is enabled to shoot 5.5K RAW movies with a frame rate of 59.94P/50P, Cannot perform auto focus. But Mr. S also said before that auto focus is convenient for people and cannot be overly dependent. Professional images need to be focused, and they are often shot manually. I think this is not a big problem for professional photographers.

Canon's new flagship EOS-1D X Mark III review

   someone might In doubt, such a 5.5K RAW video capacity should be amazing, right? Mr. S also tested and found that the total capacity of 13-second RAW video is 4.55GB, which is an average of 0.35GB/sec throughput. But to be honest, in front of the CFexpress memory card, this is simply a piece of cake. The key is to see how big your container is.

Canon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III review

   Finally, let’s watch a 1080P about 120P/100P slow motion video shot by EOS-1D X Mark III. The video comes with Canon log, and Mr. S added his own creative Look “SL CLEAN KODAK B ULTRASOFT” and slightly retouched.

  6. Canon EOS-1D X Mark III real shot proofs

Canon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III reviewCanon's new flagship EOS-1D X Mark III review

  To talk about the shooting experience, My biggest feeling is that the battery life of this camera is simply amazing. Shooting football sports themes and shooting wild animal themes add up to nearly 10,000 photos, I have not even charged a single time. It is true that the official battery life data of 2850 is often based on non-continuous shooting. If you shoot continuously, the battery life data can be multiplied by four or five minutes. LP-E19 is still that LP-E19. The powerful one is actually Canon EOS-1D X Mark III’s new low-power performance. Also, the EOS-1D X Mark III’s almost invincible focusing system. I almost don’t need to consider focusing when I shoot continuously. I only need to enable the Case A autofocus mode and turn on the high-speed continuous shooting with 16 frames per second mechanical shutter. , All kinds of wonderful moments are presented immediately. I think this is probably the supreme charm of the top flagship SLR!

   Seven, PConline evaluation summary

   Canon EOS-1D X Mark III is a professional SLR camera, so we must use professional Look at it with your own eyes. To sum up, I think it is already impeccable in terms of performance, whether you plan to use it to shoot still photos or shoot dynamic short films, it can do well.

Canon's new flagship EOS-1D X Mark III review

  If it is said that it is suitable for ordinary consumers to purchase and use, I think it is very suitable if you have sufficient funds. From my own experience, I have experienced the top performance of the camera, it seems a bit difficult for me to accept lower-level cameras.

Canon's new flagship EOS-1D X Mark III review

   no doubt , The top SLR is always the top SLR. In terms of control, image quality, continuous shooting, speed, and video, it is true that none of the full-frame cameras can compare with the EOS-1D X Mark III, and even the friends next door can’t do it. In the future, it is unknown whether Canon EOS R5, which aims at the king of mirrorless cameras, will dominate everything, but I know that EOS-1D X Mark III is still the world’s most reliable SLR camera.
