The Takumar 58mm f/2 is the only SLR lens ever produced with Sonnar design, giving it its distinctive buttery bokeh.

The Asahi Takumar 58mm f/2 occupies a unique place in photographic history. Unlike virtually every other standard lens designed for a 35mm SLR, it is based on a Sonnar-derived optical formula rather than the more common Double Gauss design. Produced only briefly in the late 1950s, it’s possibly the only example of a Sonnar-type standard lens made for a single-lens reflex camera.
Its rendering reflects this unusual heritage. Wide open, the lens produces a beautifully smooth transition from focus to blur, with gentle contrast, creamy bokeh, and an almost three-dimensional sense of depth.

This Zenith Stellina from the 1950’s features a cal. 133.8 automatic bumper movement, designed by Ephrem Jobin (the man behind the legendary prize winning caliber 135 movement). The stepped lugs are not seen often.

This is the cheapest lens in my collection. In fact, I got it for free (together with a camera). Despite its aperture not being really fast, the lens has great rendering and fantastic bokeh. Stopped down, it will give great resolution across the frane.
