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 …

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.
