This post is one of the series of posts I've written which just gives a short description and a collection of sample pictures from a vintage manual lens used on a modern digital camera. Other posts in this series covered the Pentax 50 mm f/1.7 prime, the Minolta 50 mm f/1.7 prime and the Meyer-Optik Domiplan and this post covers the Steinheil Munchen Cassar S lens.
Steinheil Munchen Cassar S lens
The lens was acquired by me as part of a purchase of a West German Edixa flex 35 mm SLR.
It's a 50 mm, M42 mount lens, with a click-less aperture which covers f/2.8 to f/16. I couldn't tell how many blades the aperture uses, but it is virtually a circle, so it must be quite a large number.
The lens is small, measuring only about an inch and a half in depth and is silver. The focus adjustment covers a large range and allows the lens to focus from infinity to about 3 feet away, and interestingly the distance scale is actually marked in feet rather than meters.
The optics have a blue look in the sunlight, so I assume there is some sort of coating to reduce reflections in the lens and therefore flair.
These samples were taken on a Sony NEX 6 APS-C camera in and around Loughborough in Leicestershire on a recent family trip. The macro images were taken with a short extension tube fitted to the lens to reduce the close focus distance. All the images were taken in RAW and processed in Lightroom CC using my normal workflow.
