This series evaluates performance of the Canon RF 50mm f/1.2L USM at medium-far distance on extremely detailed scenery across the frame which allows evaluation of lens aberrations as well as checking for focus shift and field curvature.
Includes images up to full camera resolution from f/1.2 through f/8.
There is a good reason that the Canon RF 50mm f/1.2L USM costs about $2229—it’s worth it! This is the finest f/1.2 lens I have ever used. Leica never produced a Leica M lens that could touch this f/1.2 performance (though I have yet to see the Leica 75mm f/1.25 APO-Summicron-M ASPH).
If this f/1.2 image doesn’t look amazing to you, see your ophthalmologist.
