Minolta M-Rokkor 40mm f2 for Leica M brand_Calumet the metering is accurate

the metering is accurate

and a range of magnetically-attached apertures instead of the original's somewhat awkward rubber-washer-and-insert system

Minolta M-Rokkor 40mm f2 for Leica M brand_Calumet the metering is accurateThe 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. Fairly typical light internal haze, minor dust, neither of which materially affects imaging. Smooth focusing, good diaphragm,
