test results have been added to the
Canon RF 600mm F11 IS STM Lens
This is an interesting lens from numerous perspectives, but focal length per dollar (euro, pound, etc.) is one, and focal length per lb (kg) is another.
Here is a comparison with Canon's other 600mm lens, both set to their widest apertures:
Canon RF 600mm F11 IS STM Lens vs. EF 600mm f/4L IS III USM Lens
At f/11, the RF 600 is already being impacted by the softening effects of diffraction.
Another interesting comparison is between the same two lenses at f/11.
