Contax / Yashica Yashica ML 135mm f2.8 Heritage

Overview

The Yashica ML 135mm f/2.8 is part of Yashica's ML (Multi-Layered) series of multi-coated optics for the Contax/Yashica (C/Y) bayonet mount, introduced around 1975. It arrived during the era when Yashica and Zeiss shared the C/Y system, and this lens was Yashica-made rather than a Zeiss design. Reviewers note it 'feels like a 135mm Sonnar,' hinting at classic telephoto rendering, though the actual optical formula is unknown from the reviews. It has earned a modest cult following among adapted-lens shooters for punching above its price: one reviewer calls it 'one of the best 135mm's I've ever used,' and Flickr users rate it as 'one of the best performing 135mm f/2.8 I've tried.' No established nickname or jargon appears in the reviews.

Verdict: The Yashica ML 135mm f/2.8 is a superb-value C/Y short telephoto for portrait and detail work, delivering excellent contrast, accurate color, and pleasing bokeh, with corner-to-corner sharpness by f/5.6. It's ideal for adapted-lens shooters who want a Sonnar-like 135mm at a modest price, provided they can live with some fringing in backlit scenes and a longish minimum focus distance.

Optical Character

Bokeh

Quite pleasing and smooth, though significant bokeh fringing appears in high-contrast or backlit situations.

Color

Very accurate, faithful color rendition praised for flower and portrait work.

Sharpness wide open

A tad soft wide open at f/2.8 but usable, tightening to sharp corner-to-corner by f/5.6 with remarkably low aberrations.

Flare resistance

Aberrations and significant fringing can appear in high-contrast or backlit scenes; built-in hood helps shield the front element.

Contrast

Excellent contrast overall, though black-and-white tonality is described as a tad flat.

Excellent contrast and very accurate color rendition
Pleasing, smooth bokeh well suited to flowers and portraits
Sharp corner to corner by f/5.6 with remarkably low aberrations
Usable and quite good even wide open at f/2.8
Smooth but strong focus dampening and a quiet, positive aperture click

Avoid strong backlit or extreme high-contrast scenes to limit aberrations and bokeh fringing
Rely on the built-in hood and take advantage of the long focus throw for precise manual focusing
