Leitz Summaron 3.5/35mm

This beau­ti­ful little lens just arrived and I placed it on the Sony A7R2 using a Foto­di­ox Pro M39 to NEX adapter.
Next stop will be the m4/3 test on an Olym­pus OM‑D E‑M1 and then I’ll try a film in a Bessa R or the Zorki 4k.

The lens was built in 1958 and des­pite it’s age — 60 years, it’s mech­an­ics work flaw­less. One thing I found is that the glass has haze inside, which seems to be a flaw of this lens type. You can see it when light­ing a torch through the lenses.

This first test shots show that I can­not focus to infin­ity using the Foto­di­ox adapter — hmmm.
The first series was focused to infin­ity with an aper­ture of 3.5, 5.6, 8, 11 and 16.
All shots are shot hand­held and JPEG OOC w/o postprocessing.






In the second series I used focus peak­ing at about 1m — the min­im­um focus dis­tance of the lens with an aper­ture between 5.6 and 8.
The images are shot hand­held and slightly cropped — oth­er­wise JPEG OOC w/o fur­ther post­pro­cessing. This second batch seems to be reas­on­able sharp.

100% crop …

100% crop …

100% crop …

100% crop …

I’ll update this post when I can provide fur­ther results.

In case you’d like to com­ment, it’s appre­ci­ated … and maybe, you want to check out my web­site too!


P.S. … and don’t for­get my flickr page.


    1. True, how­ever this one is not cheap and is advert­ised that it can focus to infin­ity. I‘ll have to check again … maybe it focuses past infin­ity … had already anoth­er one which did this.
