Overview

The Yashica Yashinon-DX 135mm f/2.8 is a large, well-built M42 lens with excellent build quality, described as 'similar to that of a Swiss watch'. Optically, it delivers tack-sharp center wide open, with corners slightly soft, improving by f/5.6; bokeh is smooth, but single coatings cause flare issues. Handling is a joy except for a frustrating aperture cutout window. It suits portrait photographers seeking vintage character, but the rare and pricey lens may be outperformed by Takumars for pure performance.
