Canon RF600mm F11 IS STM and RF800mm F11 IS STM review

   At the global new product launch on July 9, Canon brought a total of two fuselage EOSR5 and EOS R6 as well as a variety of RF system lens products. Among them, the products that make people feel a little “unexpected” are the two ultra-lightweight ultra-telephoto lenses to be reviewed today: RF600mmF11ISSTM and RF800mmF11ISSTM lenses. Since their launch, these two new products have had many interesting “nicknames”, such as the moon-watching mirror, the bird-shooting artifact, the aerial cannon, and so on. Indeed, from the focal length point of view, these two lenses are useful for themes such as watching the moon, shooting birds, and aviation.

   It can be seen from the focal length specification that both lenses are Positioned in the category of super telephoto. The reason why people feel “unbelievable” should be the design with the maximum aperture of F11, and there is only a fixed aperture of F11, which cannot be contracted. Since the announcement of the two lenses, RF600mmF11ISSTM and RF800mmF11ISSTM, in the face of this relatively unique specification, it is not difficult to hear many doubts. Among them, there are many puzzles about the scope and function of the ultra-telephoto lens. Doubts about the F11 aperture design. Before the actual shooting experience of these two lenses, I also have the same puzzles as above, and this time I will also bring this curiosity to find the stage where these two lenses can exert their strength.

Canon RF600mm F11 IS STM and RF800mm F11 IS STM review

  RF600mmF11ISSTM and RF800mmF11ISSTM are unique in that they are relative to their focal length specifications In terms of the size of these two lenses are very “mini”, at the same time there is a very light weight. Among them, the weight of RF600mmF11ISSTM is 930g, and the weight of RF800mmF11ISSTM is 1260g. Compared with professional-grade 600mmF4 or 800mmF5.6 lenses, there is a huge difference in size, and the price is less than one-tenth of theirs. Therefore, it is not difficult to explain, in order to be lightweight and compact, some aperture values ​​had to be sacrificed. But compared to the current top specifications of 600mmF4 or 800mmF5.6, the aperture is only 3 stops and 2 stops smaller. Although these two lenses are lightweight, the materials used are unambiguous. Both use a seamless double-layer structure DO lens, which can effectively suppress glare even when there is a strong light source in the screen, and achieve the high image quality of the lens. At the same time, it also contributes to the miniaturization of the lens.

   Here I still want to emphasize the ultra-long focal lengths of 600mm and 800mm, which are by no means the angle of view that can be achieved with conventional 200mm or 400mm telephoto, and the lightweight lens body plus the maximum equivalent of 5 The IS image stabilizer with level/4-level shutter speed compensation provides strong support for handheld shooting. Such an ultra-long focal length is also very suitable for shooting wild birds, animals, airplanes, trains, scenery, moons, outdoor sports and other different subjects in a handheld state, allowing more users to experience the charm of super telephoto lenses Where. The STM stepping motor brings a quiet and smooth autofocus. When shooting movies, you can get a smoother focus tracking and focus transition effect. The official price of RF600mmF11ISSTM lens + lens hood ET-88B is 5,298 yuan, and the official price of RF800mmF11ISSTM lens + lens hood ET-101 is 6,798 yuan, which is also Canon’s current cost-effective RF telephoto lens choice Up.

   Lens Appearance Show

   As two lightweight products of the same level, Canon RF600mmF11ISSTM and RF800mmF11ISSTM have a high degree of similarity in appearance. The lens body is made of plastic material. To a certain extent, it is also optimized to reduce the overall weight of the lens. Both lenses have a leather-like plastic texture on the front, which can increase the friction when grabbing me. The lens body is biased towards cool gray with a delicate matte texture.

   These two products are designed with a silver control ring in the middle of the lens. Users can assign functions such as shutter speed, ISO sensitivity, and exposure compensation to the control ring of the lens according to their habits, thereby greatly improving the convenience of operation. When the control ring rotates, it has a sense of positioning and operation sound, which is convenient for users to grasp the amount of operation. With Canon EOSR5 and EOSR6, white balance, color temperature, photo style, and auto focus can also be assigned to the lens control ring. It is worth noting that because these two lenses use F11’s fixed aperture design, the aperture value cannot be set.

   The layout of the Canon RF600mmF11ISSTM and RF800mmF11ISSTM lenses on the operating unit is almost the same, including the focus distance selection switch, manual autofocus switching and anti-shake mode switch. The focusing distance of the Canon RF600mmF11ISSTM lens can be limited to 12 meters, while the RF800mmF11ISSTM lens is 20 meters.

   The most unique design of these two lenses is the retractable storage structure at the end of the lens. When in use, you need to turn the lock ring to unlock, pull out the end structure and turn it again to lock it to use. After installing it on the camera, a corresponding prompt will appear. It is more convenient to go out and portable after shrinking.

   because the Canon RF600mmF11ISSTM and RF800mmF11ISSTM lenses only The first-stop aperture of F11 can’t use the traditional idea of ​​shrinking the aperture to get better picture quality, so the full-open picture quality of the lens is the top priority. Judging from the real shots, Canon’s RF600mmF11ISSTM and RF800mmF11ISSTM lenses are very good in image quality, with high sharpness resolution, and very high imaging standards from the center and edge.

   As an ultra-telephoto lens, its anti-shake level is also very important. According to official data, Canon’s RF600mmF11ISSTM and RF800mmF11ISSTM lenses can reach the nominal level 5 or level 4 anti-shake level. Here, I conducted a real measurement of the RF800mmF11ISSTM lens. The anti-shake performance of the RF600mmF11ISSTM is better than that of the RF800mm, so the level of anti-shake can be used as a reference.

   In the handheld shooting, due to the long focal length, the slight The shaking will affect the composition and framing stability, and these two lenses can be easily stabilized in the handheld state. Through the actual measurement and subsequent outdoor shooting experience, with the help of anti-shake and shooting at a lower shutter speed such as 1/20s or 1/10s, a very high success rate can be obtained. You know, these are 600mm and 800mm lenses.

  As an ultra-telephoto lens, although the Canon RF600mmF11ISSTM and RF800mmF11ISSTM lenses suffer from loss of light in the four corners, it does not affect the overall effect of the picture, which can only be seen in the picture with a solid background.

   Generally speaking, the telephoto lens has a narrower angle of view, so it is not easy to show obvious glare. This can be proved by real shooting. In terms of dispersion performance, after shooting high-light objects, the two lenses have no dispersion in the screen. Therefore, after various actual tests, it is proved that the performance of Canon’s RF600mmF11ISSTM and RF800mmF11ISSTM lenses are quite balanced, and can be taken with confidence in various subjects without worrying about the quality of the lens itself.

  Picture sample

  With Canon EOSR5, I used Canon RF600mmF11ISSTM and RF800mmF11ISSTM two ultra-telephoto lenses to shoot some video clips of different themes. These two lenses are in focus tracking and The switching has excellent performance, and the space compression feature brought by the ultra-telephoto also brings unexpected visual effects to the picture. The video was shot in FHD size, with the help of a monopod/tripod and hydraulic head.

   Generally understood, shooting subjects for such ultra-telephoto lenses, including the moon, birds, wild animals, airplanes, trains, etc. Here, I also used Canon’s RF600mmF11ISSTM and RF800mmF11ISSTM two ultra-telephoto lenses to try to shoot these subjects, and the picture effect I got was amazing. Both the sharpness of the picture and the success rate of focus tracking are very high. F11 aperture can also get a very charming blur effect at this focal length, and the ultra-telephoto can bring the space charm that is usually difficult to feel. Even under a slow shutter speed of 1/15s or 1/8s, a clear picture was successfully shot.

  More picture samples and evaluation summary

   Presumably for a wide range of users, there will not be too many opportunities to contact the ultra-telephoto lens, so these two lenses will also be Excellent super telephoto “stepping stone”. Here I also want to briefly share some experiences when shooting with RF600mmF11ISSTM and RF800mmF11ISSTM. I usually set the shutter speed above 1/200s to ensure a higher success rate of capture, and let the sensitivity adjust automatically according to the metering. Although the sensitivity is often very high when the light changes greatly, thanks to the powerful EOSR5 body, I am not worried about the impact of sensitivity on the image quality.

   Generally speaking, not only watching the moon, shooting birds, aviation, and many other broad subjects, the scope of use of these two lenses is far more than that. In use, these two lenses are more like light and anti-shake “monocular” telescopes, and are much more convenient than traditional telescopes that require complex focusing. You can clearly see the distance when you turn on them at any time. Scenery, this is also an experience that has never been experienced before.

  Of course, unavoidable Not to mention that the use of these two lenses in low light or indoor environments will rely on higher sensitivity because the aperture is only F11, but the high level of sensitivity in the current EOSR series products is very good. Especially EOSR5 can still get delicate picture quality under ISO6400, so it is not difficult to believe that Canon relies on the better high-sensitivity performance of the camera itself, thus designing a small aperture lens to control the volume and cost, breaking the previous impression For the definition of lens parameters and specifications, Canon’s RF600mmF11ISSTM and RF800mmF11ISSTM are the answers Canon has given. Lightweight, compact and inexpensive lenses are the products that a wider user group is willing to buy and use.
