    Posted: 28 October 2013 at 20:39
Part one is here.

I went to Gustav's home yesterday to do some further testing of wide angle lenses on the new Sony a7R FF mirrorless camera.
This time I wanted to test less extreme wide angles (28 and 35mm) and some wide angle non-rangefinder lenses.

Once again I want to thank Gustav to let me use his pre-production a7R for this test and to make time (and coffee ) for me!

This was a fantastic opportunity because it enabled me to do this important test. Important? Yes, because ever since the news was leaked about this camera, the big question in rangefinder land has been: how will it perform with wide angle rangefinder lenses? And don't underestimate the number of inhabitants of that land: since I uploaded the test shots on Flickr on Saturday night, the 50 or so photos have had > 300.000 views!

OK, enough said (but I can't thank Gustav enough!).

These were all taken in a park near Gustav's home. Very bright spells alternated with heavy cloud; strong winds. Camera on tripod; ISO 200; no steady shot (sorry, bad joke).

Full size JPEGs on my Flickr site (clicking on a photo will take you there).

This time I will not show you all apertures here: if you want to see them all, go to my Flickr account. Of each lens, there's a wide open shot and one of F8 or F11, the 'normal' aperture for landscapes. Focus is on the bridge, checked with magnification and focus peaking.

1 Voigtlander Ultron 28_1.9 F1.9


2 Voigtlander Ultron 28_1.9 F8


3 Orion 15 28_6 F6 (a Russian rangefinder lens)


4 Orion 15 28_6 F16 (I seem to have missed F11)


5 Voigtlander Color-Skopar C 35_2.5 F2.5


6 Voigtlander Color-Skopar C 35_2.5 F8


7 Leica Summicron M 35 ASPH F2


8 Leica Summicron M 35 ASPH F8


And two I tested on Saturday too:

9 Voigtlander UW Heliar 12_5.6 F11


10 Voigtlander Color-Skopar 21_4.0 F11


Finally 3 wide angle non-rangefinder lenses; and it is clear that the design of the lens is the issue here:

11 Olympus OM 18/3.5 @ F3.5


12 Olympus OM 18/3.5 @ F8


13 Carl Zeiss Jena Flektogon 20_4 F4


14 Carl Zeiss Jena Flektogon 20_4 F11


15 Pentacon 30_3.5 F3.5


16 Pentacon 30_3.5 F11


Again: these were taken with a pre-production camera and pre-production firmware! So this test isn't the final word.

From the lenses above I have the Voigtlander Color-Skopar 35mm F2.5 and the Voigtlander Color-Skopar 21mm F4. The results seem very similar to what I see on my NEX 7.
So not good, but not bad... I learned how to live with it...

Thanks for sharing, Leo!

BTW, out of topic a little bit... When I first saw the design of the cameras I was worried about the location of the shutter button. Is it easy to get the finger to it?

You're welcome Shay! and I enjoyed doing it.

I had no problem finding the shutter button, no.
There are a lot of buttons on a very small area and one of the programmable buttons is not within easy reach I think, but we'll get used to it.
I liked the handling of the front and back-wheel buttons: on the A99 you feel some resistance sometimes, even so much that they won't turn; not so with these wheels.

Did you, by chance, try Gustav's Sony CZ 50 on the A7?

Thank you very much, Leo, for this great overview on a variety of WA lenses - this is truly helpful for deciding whether the a7R will provide a sound basis for classical and vintage lenses as well. I did expect some of the results - e.g. the magenta corners of the 21mm Color-Skopar (I sold mine).

But What I find really striking are the good results for the 18mm Olympus and the 20mm Flektogon. They are the only retro-focus lenses in your test, AFAIK? I would have loved to see a comparison of the 18mm (retro-focus) ZM Distagon and one of the (short-focus) ZM Biogons.

What are your insights about retro-focus vs. short-focus from your test?
