In the mirrorless camera, in addition to the common full-frame mirrorless and APS-C format mirrorless cameras, there are also seemingly “niche” existences-M4/3 format, the M4/3 system is based on the early 4 The /3 system has evolved. Compared with the full-frame and APS-C format, the M4/3-frame mirrorless camera has a better performance in the control of volume and weight, and the advantages of small size can also provide special and Exclusive features. When it comes to M4/3 format, one of the big brands I have to mention is Olympus. 2019 coincides with the centennial of Olympus’s establishment, and it also brings a new work in the M4/3 format-Olympus E-M5MarkIII.
2019 is Olin The centennial day of the establishment of Bath is also the 80th anniversary of the birth of Olympus cameras. The release of E-M5MarkIII is obviously a tribute to Olympus’ centennial birthday. And this gift is also quite “solid”-the first is to install the same 20.4 million pixel 4/3LiveMOS sensor and TruePicVIII image processor as the higher-level E-M1MarkII, in addition, it also provides a 121-point full cross phase detection automatic Focusing system and continuous shooting speed up to 30 frames per second in silent mode.

In addition, Olympus E-M5MarkIII is also equipped with Olympus’s “traditional arts”-five axis Body anti-shake function, but its anti-shake function has been significantly upgraded, first of all, it can now provide up to 6.5 stops of anti-shake compensation effect; in addition, the number of pixels in the high-pixel mode of “Shaking Le” is also from the previous generation of 4000 Megapixels are upgraded to 50 million pixels, and 80 million pixels can be recorded in RAW format files, which is amazing. In this article, we will use the lens M.ZUIKODIGITALED12-40mmF2.8PRO for testing.
Appearance details introduction
The overall appearance of the Olympus OM-DE-M5MARKIII body is not very different from the previous generation , Still adopts a dazzling retro-style design, the top of the warship adopts the iconic triangle design, and the changes are concentrated in the fuselage lines, full of metal, looks very hard core, in addition, this camera is also dustproof and waterproof Splash performance.

Olympus E-M5MarkIII has obvious changes at the top of the fuselage. The position of the mode dial is from the top left of the fuselage. The side is adjusted to the right for better operation. In addition to the switch on the left side of the fuselage, the original mode switching dial has been changed to a continuous shooting/self-timer timer button and a button for switching the live view view.

In the control area, it is still a familiar button configuration. I believe users can get started quickly. However, the direction of the shift lever has been adjusted, and the auto focus/auto metering lock button in the shift lever is now clearly marked, which reduces the learning cost of the user during use.

In addition, compared with the previous model, Olympus E-M5MarkIII has further expanded the handle area, with the same enlarged The thumb position has a better grip and experience. With the increase in the area of the thumb, the ISO adjustment button originally arranged on the top of the fuselage is also placed near the thumb.

Olympus E-M5MarkIII battery compartment
is at the bottom of the fuselage, there is a battery compartment and communication with the handle Metal contacts. The battery compartment uses an independent locking design, which is also a major guarantee for its dust and splash resistance. It uses a BLS-50 battery, which is different from the B-LN1 battery used in the previous model. The BLS-50 has a capacity of 1210mAh, and official data claim that its battery life has reached 370 batteries. In my actual use, this battery can support a day’s use when combined with camera and video shooting. What’s more, E-M5MarkIII also supports USB charging function, which better guarantees its battery life.
Sensitivity ISO real shot test
Olympus E-M5MarkIII replaced with a 20.4 million pixel sensor derived from E-M1MarkII , And equipped with TruePicVIII image processor. Compared with the 16.1 million pixel sensor on the previous model, the number of pixels of E-M5Mark III has been improved to a certain extent, and the improvement of the pixels will have an image of the high sense of this machine. The way to show.
Olympa The sensitivity range of E-M5MarkIII is ISO200-25600, and it provides a low-value ISO extension of ISO64. At ISOLOW, that is, ISO64, the degree of preservation of picture details is the highest. Starting from ISO1600, there is a slight noise, and at ISO3200, the amount of noise further increases, but the image details are still preserved, and at ISO6400, the details of the picture begin to be lost. When it reaches the limit of ISO25600, there is a more obvious color attenuation. Overall, the Olympus E-M5MarkIII has a higher image availability at ISO3200 and lower.
High-speed continuous shooting experience
One major feature of the M4/3 system is that it is fast, which can provide professional, high-speed focusing and continuous shooting Experience, E-M5MarkIII also has good data, up to a continuous shooting speed of 30 frames per second. The E-M5MarkIII also provides different continuous shooting modes: in the ordinary continuous shooting mode, it is divided into high-speed continuous shooting and low-speed continuous shooting. The maximum continuous shooting speed is 10 frames per second. It also provides low-speed anti-shake continuous shooting. At this time, the continuous shooting speed is 5.5 frames per second; in addition, it also provides high/low speed silent continuous shooting and high/low speed professional capture. Its highest continuous shooting speed reaches 30 frames per second, and we also adopted the production of GIF animation. Way to show.
30 sheets/ Second continuous shooting
When using a continuous shooting speed of 30 frames per second, the machine will use an electronic shutter without sound and vibration. In a high-speed silent continuous shooting mode of 30 frames per second, approximately 23 RAW format pictures or 26 JPEG format pictures can be recorded. When switching to the low-speed continuous shooting mode of 10 frames per second, you can continuously shoot about 150 RAW format pictures, or shoot JPEG pictures until the memory card is full.
one frame of continuous shooting
And another point that needs to be mentioned is that Olympus E-M5MarkIII also has a professional continuous shooting function. A “pre-shooting” function is added. Specifically, when the shutter button is pressed halfway, the camera starts to take images, and when the shutter button is fully pressed, it can capture up to 14 frames of images. This is also convenient for us to obtain a specific photo we want in rapid continuous shooting.
Excellent anti-shake effect is a business card of Olympus cameras. On the Olympus E-M5MarkIII, the anti-shake effect of up to 6.5 stops of safety shutter can be achieved. We also tested the anti-shake effect of this body. In the test, we used the wide-angle end of M.ZUIKODigitalED12-40mmF2.8PRO, that is, the 12mm end, which is equivalent to a 35mm full-frame focal length of 24mm. I set the camera to the shutter priority gear and reduce the shutter speed step by step from the safe shutter speed. Take a picture, and take 3 pictures at the same time at each shutter speed to see if a satisfactory anti-shake effect is achieved.
From the comparison chart We can see that when the shutter speed is reduced to 1s, because the amplitude of the jitter exceeds the range that can be compensated, the picture appears jittery. But what I have to say is that when the shutter speed is 1s, there is still a certain chance to take a more usable image. Olympus officially stated that when combined with the M.ZUIKODigitalED12-40mmF2.8PRO lens we used in our test, it can achieve about 5.5 stops of anti-shake compensation, which is obviously basically reached from our real shooting experience. .
High pixel mode experience
With the full-frame sensor can reach 60 million pixel level, many users also have a certain degree of high pixel pursue. In the Olympus E-M5MarkIII, this small M4/3 body, in high resolution mode, it can output 80 million pixel RAW format pictures and 50 million pixel JPEG format pictures. This is based on the pixel shift function provided by the body’s anti-shake mechanism. In the high pixel mode, the image sensor will move in increments of 0.5 pixels while the camera continuously captures eight images for synthesis. We also use real shots for comparison.
80 million pixel RAW to JPG original image
After exporting, the resolution of the JPEG file is 8160×6120, while the resolution of the RAW file has reached 10368×7776. You can see that the details of the picture have been improved to a certain extent. But one thing that needs to be mentioned here is that when using high-resolution mode, it is recommended that you always use a tripod to shoot, because the pixels are very high, and slight jitter will also cause loss of detail.
Video function experience
Compared with the previous generation E-M5MarkII, E-M5MarkIII besides the traditional 1080P video recording, It also provides C4K/24P with a resolution of 4096*2160 or 4K/30P with a resolution of 3840*2160. The highest video bit rate reaches 237Mbps, and the highest bit rate of 1080P video reaches 202Mbps. In addition, this camera can also shoot high-speed video at 1080P/120fps.

In the process of video shooting, E-M5MarkIII can combine the five-axis image stabilization unit with the video electronic stabilization function, which in theory will have a good defense Shake effect. From our actual shooting experience, the effect of video anti-shake is really good. In addition, E-M5MarkIII also provides a “Flat” video screen mode, which is a screen mode added specifically for shooting dynamic videos. Performing color grading processing on the captured video can increase the range of video grayscale expression. Users can use relevant application software to perform operations with the help of the query form file.
Real shot proofs
The lens with E-M5MarkIII in this evaluation is M.ZUIKODIGITALED12-40mmf/2.8PRO, which belongs to The PRO series of lenses can bring excellent imaging capabilities. The 12-40mmf/2.8 has a wide range of applications. The equivalent 24-80mm focal length is very suitable for on-hook or travel use. It has excellent close-range shooting capabilities and has an excellent combination with the body The anti-shake effect.

One thing that can be noticed is that in low-light scenes such as night scenes and indoors, due to the excellent anti-shake effect, some In this case, you can use a lower sensitivity to shoot, and the image quality is also very good.
Editor’s point of view
has 20.4 million pixels derived from the higher-level E-M1MarkII The sensor and TruePicVIII processor have greatly helped the performance of E-M5MarkIII. To a certain extent, this machine has the data level of the flagship model. On the five-axis anti-shake, the anti-shake effect of up to 6.5 gears has a very good performance when taking photos and videos. Continuous shooting of up to 30 frames per second may not be a common feature, but it is also a demonstration of the camera’s own strength. In addition, what I have to say is the high-pixel mode that can output up to 80 million pixels. As the first manufacturers to use this feature, the high-pixel mode can also provide more possibilities for this camera.
In short, the appearance of E-M5MarkIII can be said to be a “cardiotonic agent” for the M4/3 camp. The M4/3 system is The high-performance features make us deeply impressed, and the Olympus E-M5MarkIII, whether it is its retro and lightweight design, or its excellent performance in image quality and anti-shake, also left us a deep impression. . From a certain level, this camera is enough to directly compete with some mid-range SLRs, and the Olympus E-M5MarkIII has features that other models do not have. Of course, the only shortcoming of this machine is the price-the current price of a single body is 9199 yuan. Looking at the entire camera product, E-M5MarkIII may be slightly inferior in terms of cost performance, and we also look forward to the price. After loosening, this machine will have a more cost-effective performance.
