At 63 mm past the mount, the RF 35 mm 1Subtract or not, how do you explain that the 35/2.8 is a centimeter longer than the 35/2.0?
8 Is is still 23 mm longer than this 35 mm 2.8. I don't think macro capabilities are only adding a cm to such a lens. I would simply guess that the longer lens has more corrective elements? In any case, it is still small.
