Leica Summar 5cm F/2.0

I first thought that this was an older version of Summicron which is also F/2.0 but it turns out that this is very different than Summicron.  It is collapsible, Screw-mount, there is no “stops” in the aperture ring so it runs freely just like focus ring.  Either it has no coating or single-coating.  This copy has plenty of cleaning marks on the front lens element.

The best part is that I can attach this on a LTM adapter and use it on any M-mount cameras including M7/M8 !!!

As expected, it is weak at flares, smooth contrast yet sharp.  It would be very good for B&W shots but I also find that it works just fine on my M8 with color shots.

I am going to keep this one for a while and see how it captures the images for me….
