中古 Schneider Kreuznach Componon-S 引き伸ばしレンズ 50mm f/2.8 ねじ込み M39

The threads are perfectly clean, and the aperture ring clicks with satisfying precision. I’ve been using it to make 11x14 prints from 35mm negatives, and the edge-to-edge sharpness is exactly what I hoped for.

I was surprised how crisp the contrast is on my test negatives; even at f/2.8 it holds detail across the frame. This lens made my 11x14 prints noticeably sharper than my old enlarging lens.

The glass arrived spotless and the aperture ring clicks with that reassuring precision you want in a darkroom tool. Shone through a full session of 35mm negs and the contrast on my fiber prints was exactly the punch I'd been chasing.
