Here is another good Canon RF 600mm f/11 review. The RF 600mm f/11 and RF 800mm f/11 made quite a splash when they were announced. Initially seen with skepticism, they are now getting a lot of positive feedback.
After having reviewed the RF 800mm f/11 lens, Christopher Frost dedicated his attention to the RF 600mm f/11.
If you are interested there is an interview with the engineers who developed these lens. Also, Canon already said there will be more such lenses. For more Canon RF 800mm f/11 and RF 600mm f/11 review stuff have a look here.

From Canon’s press release:
Canon RF600mm and 800mm F11 IS STM
The Canon RF600mm and RF800mm F11 IS STM lenses are the first fixed focal length super-telephoto RF lenses and are incredibly compact and lightweight. The portability of the new lenses is made even greater due to the ability for the lens barrel to retract and lock in place when the lenses are stowed away and not in use. Diffractive Optics technology helps to reduce the necessary number of lenses and greatly diminish the cost of the lenses, making them affordable for a broader group of photographers. Additional features of the Canon RF600mm and RF800mm F11 IS STM lenses include:
- Lightweight – the RF600mm weighs approximately 2.05lb and the RF800mm weighs approximately 2.78lb, respectively
- Compact size, RF600mm measures approximately 7.85inch and RF800mm with measures approximately 11.09inch when retracted, respectively
- Fixed f/11 aperture
- Optical image stabilization of five stops* for the RF600mm and four stops* for the RF800mm of Shake Correction
- Lead screw-type STM enables smooth auto focusing for still-image and video shooting
- Customizable control ring that allows photographers to adjust exposure compensation, shutter speed, aperture or ISO
- 12-pin Communication System
- Compatible with the new 1.4x and 2x RF lens extenders
