Contax / Yashica Yashica 135mm f2.8 Heritage

Overview

The Yashica ML 135mm f2.8 is part of the Contax/Yashica (C/Y) bayonet system introduced in 1975, a mount shared between Contax and Yashica film SLR cameras. Within that system, the Yashica ML line was positioned below the Carl Zeiss offerings — reviewers describe the ML lenses as 'not as good as their Zeiss counterparts, but still excellent if you know what to look for.' This particular 135mm is a Yashica-made unit, and one reviewer notes it 'feels like a 135mm Sonnar' in its rendering and handling. It carries no established nickname (unknown). Its cult appeal comes from delivering strong optical performance — excellent contrast, accurate color, and pleasing bokeh — at a budget-friendly price, with one reviewer calling it 'one of the best 135mm's I've ever used.' It adapts easily to mirrorless bodies, adding to its enduring appeal.

Verdict: The Yashica ML 135mm f2.8 is a budget-friendly short telephoto that delivers excellent contrast, accurate color, and pleasing bokeh with a Sonnar-like feel. Slightly soft wide open but sharp corner-to-corner by f5.6, it earns high praise from at least one reviewer as among the best 135mm lenses they've used. Ideal for portrait and telephoto shooters on a budget who want strong optical quality on C/Y film bodies or adapted mirrorless, and who don't mind a long focus throw.

Pro Tips

Shoot at f5.6 for maximum sharpness across the whole frame including corners.
f2.8 is quite usable when you need the speed or shallower depth of field, accepting slight softness.
Use the built-in hood and expect the long focus throw — take your time nailing focus, especially adapted to mirrorless with focus aids.
For B&W work, be prepared to add contrast in post since tonality can run a tad flat.
