Not long ago, Canon officially released two RF series ultra-telephoto lenses-RF800mm F11 IS STM and RF600mm F11 IS STM. Their appearance makes people feel bright, greatly expanding the focal length coverage of the RF series lens, and at the same time, the light and compact shape also breaks the inherent impression of the heavy and bulky ultra-telephoto “cannon” in the past. In the SLR era, the professional 800mm telephoto lens was more used to shoot birds and wild animals, while the 600mm focal length could shoot sports, aviation, and animals. In the era of mirrorless, Canon released these two lenses in the hope that ordinary users can also experience the fun of super telephoto. The small and light-weight RF800mm F11 IS STM and RF600mm F11 IS STM have become the “artifacts for bird-fighting” and “aviation artillery” for the people.
Lightweight appearance design, easy to control
Compared with the EF professional SLR “cannon”, these two lenses are obviously “slim”. The RF800mm F11 IS STM weighs only 1260 grams, while the RF600mm F11 IS STM weighs 930 grams. It is far better than traditional “cannons” in terms of equipment portability.
As an ultra-long prime lens, the two lenses are indeed very delicate in appearance. The main body of the lens is made of light and high-strength resin material, with a silver multi-function control ring, which is highly recognizable as a whole.
The shell near the front of the lens adopts a particle coating for the convenience of the photographer Hold the mirror body firmly.
RF800mm F11 IS STM and RF600mm F11 IS STM use a fixed aperture Design and push-pull structure, the greatest degree of “burden reduction”. The bottom of the lens is equipped with a lens barrel lock. When shooting, you need to unlock it, push the lens barrel forward and lock it again, then the lens will enter the shooting state, otherwise it cannot be used normally.
The rear mounts of the two lenses are made of metal to ensure durability.

and RF600mm F11 IS STM has a slightly smaller caliber, 82mm.
Both lenses are equipped with focus distance selection, AF/ MF switch and anti-shake switch, convenient for photographers to quickly adjust the focus and anti-shake state.

Using DO lens technology to perform excellent image quality
RF800mm F11 IS STM and RF600mm F11 IS STM in addition to lightweight appearance, also adopted A new generation of DO lens technology, using a new micron-order diffraction grating stack structure, one DO can achieve the compensation effect of multiple fluorite and aspheric lenses in the traditional structure. In this way, the number of lenses is simplified and the image quality is guaranteed.

What is the outdoor imaging performance of these two lenses? I took them for real shots.
First, let’s take a look at the real shot samples as the “Bird Fighting Artifact”:
Through real shots, I think the sharpness of the RF800mm F11 IS STM is very good, shooting at ultra-long distances Time sharpness is still not affected too much. When paired with the EOS R5 body, the performance of the new 45-megapixel sensor can be brought into full play. The details in the zoomed-in picture are very rich. Even with high-sensitivity shooting, the resolution is no problem.
Next is the real shot of the “Aviation Artillery”:
The actual image quality of the RF600mm F11 IS STM is basically the same as that of the RF800mm F11 IS STM, whether it’s mid-range or ultra Long-distance shooting, the sharpness performance is very stable, and the imaging resolution is high. Thanks to the use of DO lenses, it achieves a balance of portability and image quality.
Blurring still experience the fun of telephoto
Although the fixed aperture of F11 is used, these two lenses still have good background bokeh ability, using ultra-long focal length, photography The teacher can easily take beautiful photos, and effectively blur the distracting objects and highlight the subject.

Using STM motor to focus quickly and quietly
The focusing performance of the telephoto lens is very important. Canon matches these two lenses with the STM stepping motor of the lead screw unit. It has the characteristics of fast response speed for focusing start and stop, which can realize quiet and smooth autofocus, whether it is taking photos or videos.

With lens IS Anti-shake system
“Bird Artifact” and “Aviation Artillery” all have a built-in lens anti-shake system, but it should be noted that when paired with EOS R5, the anti-shake system of the body and the lens cannot be activated at the same time. Shake function. According to official information, the anti-shake performance of the RF800mm F11 IS STM can reach up to level 4, and the RF600mm F11 IS STM can reach up to level 5.
For shooting wild animals or sports, the flexibility of the handheld is often better, and it can lock the target faster and keep tracking. Therefore, the success rate of handheld shooting is significantly improved after IS anti-shake is turned on. Coupled with the small and light weight, photographers can experience the powerful mobile firepower of super telephoto.
RF800mm F11 IS STM and RF600mm F11 IS STM ultra-telephoto lens The release makes the Canon EOS R mirrorless system even more powerful. On the basis of ensuring the image quality, Canon uses DO lenses and other lightweight technologies to transform them into “portable cannons”, which can be easily shot in the hand. This is professional at the same focal length. Cannon has an incomparable advantage. Through the real shots, I feel that these two small cannons can work well with EOS R5. Both focus and image quality are good. They basically display the characteristics of the EOS R5 high-pixel body, which is enough to meet Canon’s full frame. There is no need for users to take ultra-telephoto shooting. Coupled with the lower prices of the two lenses, it is believed that in the future, “Bird Fighting Artifact” and “Aviation Art Cannon” will be popular among users.
