The Zeiss Touit 50mm f/2.8M is nominally an APS-C lens, but like all lenses it “covers” more than that size. Why not consider it for the classic aspect ratios of one’s choice, and with high quality and more megapixels?
Zeiss Touit 50mm f/2.8 Macro on Sony A7R: Classic Aspect Ratios
Includes HD and UltraHD images from f/2.8 through f/11 for 3:2, 4 X 5, 6 X 6, 4 X 3, 6 X 17 aspect ratios. All but the 617 format exceed the nominal APS-C megapixel count.
Shown below is the classic aspect ratio of 6 X 6 film (and Hasselblad 503CWD).
UPDATE: I've requested the Touit 12/2.8 and Touit 32/1.8 and will likely evaluate the image circle on those lenses as well, and perhaps macro range also (for the 50mm).
In field of view terms, the 12mm is equivalent to an 18mm lens on full frame, but if a larger image circler offering greater sensor coverage, then perhaps a field of view equivalence near 16mm or even 15mm might be possible.
