Minolta M-Rokkor 40mm f2 for Leica M format_Medium Format 8G ED DX Nikkor isThe Minolta M Rokkor 40mm f2 is tiny really tiny. It's barely 2cm long and as wide as the M mount at its widest point, making it an ideal everyday lens if you don't like bulk. The 40mm focal length is excellent for both full frame and crop bodies, and the f2 aperture is impressive for the size. Anyway, big fan of this lens. It's clean, with smooth focusing. Fits any M mount camera.
