>>3546502Jupiter-9 85mm f/2. The Zenitar is a far better Zeiss copycat.
>>3546720Very small, like the Voigt' 35mm f/1.4 or the Canon 35mm LTM (can be a problem if you have sausage fingers). Built like a Leica, smooth focus like a Leica. Good center sharpness, nice aperture clicking. A recommended travel lens and the best first M-mount to buy. Pic related.
Better options are the Zeiss Biogon (way fatter) and the Summicron (way pricier).
