Beautiful indeed!
I´m looking into the 24 and 35mm f/1.8 macros for documenting some biological stuff that would benefit from a flat field the size of around 1x1 ft perhaps a bit larger. I presently use the 24-105STM that is sharp enough in the part of interest, but has a curved field forcing me to use higher f/ than I like. If the 24mm works for docs and flat art, I suppose I can hope it would be flatter than the zoom?! Oh, feeling some incoming GAS here...
Like all new RF designs, the RF 24 1.8 Macro IS STM is designed to be used with software correction for barreling and light fall off. With default JPEG (in-camera) or RAW (software) corrections enabled docs and flat art are true and accurate. With that said, if you disable lens profile corrections in LR, there is some barreling and light fall, However, the amount is considerably less compared to the RF 24-105 IS STM zoom. That zoom totally blacks out in the corners!
The RF 35 1.8 Macro IS STM is a little easier to use if you actually work close to the .5X magnification. At 24mm .5X is a bit too close to get decent light on the subject. Plus, the RF 35 1.8 Macro IS STM has a groove for the Canon's ring light.
