Voigtlander Ultron 35mm F2 Aspherical Images

A new lens needs a new thread for images taken with the lens, so here we go. Feel free to post images if you have this lens!

Here's a few quick shots snapped today with my new Ultron to finish off a roll of film. Nothing artistic.

Looks pretty much distortion free to me.

And handles shooting into the sun just fine.

I'm imagining Jon typing that post with one hand while he agitates the first roll of film shot with the new Ultron with the other...

ETA: That was said when the OP was just "stay tuned" ...

Here you go. F2 @ 1/30 then F4 at 1/8 hand held (did my best, but don't go judging sharpness from this).

Probably! No worries. Just the detritus of a dynamic environment.

Photos look good. Nothing to complain about so far -- I suspect this lens will make lots of people happy. Always good to have another semi-fast high-quality 35 in production!

Jon, I wish my "few shots to finish a roll" were as nice & interesting as these!

Distortion and bokeh are OK with me. I like the bokeh a lot!

Thank you, Jon, for this test.

It is ok on mobile phone, but on large screen wide open photos comes with swirl and buzz.

Are all Ultron lenses with identical lens design? I have a 50/2 Ultron, for example.

Here is 28 ASPH and none. So oltical elements inside of the lens are different.

Thanks for the bokeh test, Jon!

This lens seems to be ticking a lot of boxes: no distortion, good flare resistance, bokeh with a bit of "character" wide open and smoothes out stopped down, good contrast for b&w.

Plus it has a unique physical design and cool hood, and the price isn't crazy! I'm feeling GAS-y, even though I just got out of the 35mm focal length.

I see some pincushion distortion. Look at the main building’s vertical line on the right.
I see the same w my Leica Summicron 35 asph...

negligible, as is the cron asph. unless straight lines at the edges are incredibly important to you, i think its a non-issue.

I think that's actually converging verticals, though pincushion could be mixed in there. I don't really see any in the flare test shot.

Yeah, same with me, bokeh looks good at first sight!
I'm waiting for a bokeh comparision with the Ultron f1.7, that I own.
Maybe I'll exchange it because of size and the focus stick of the new one

(my Ultron f1.7 has only a ring and I'm missing a fast lever)

Historically the Ultron is a double-gauss derived, non-symmetrical design. Not so with the modern ones though. Cosina seems to prefer applying the Ultron as a designation to f/2-ish lenses just the way Leica uses the Summicron name.

This one is a non-symmetrical compact retrofocal design similar to, but not exactly the same as the 35/2 ASPH.

Looks good indeed. Might there be any test on focus shift?

Maybe it is your screen that causes the distortion. On my screen (SynchMaster943) it is perfectly allright.

bokeh and everything remind me on old Ultron ltm... i have it and i love it! but i think this new one have better contrast. (also lens design scheme is pretty close to ltm version-if i found good ones-it was really hard to track them down)

Seems like a pretty good "straight up the middle" performer, Jon. I'd echo the question about focus shift, but it seems like a winner. I have a 35/1.2 Nokton that I love. . . here's hoping that the f:2 is its reasonably priced little brother.

Nice snaps too . . . :bthumb:

I haven’t seen anything official but I saw a post from someone that was not camera quest on FM forums that camera quest is taking preorders starting tomorrow with Feb 5th shipping.

Pretty surprised there hasn’t been an official announcement here.

Yes and big thanks to Jon for the samples.

I think you're seeing perspective distortion. Looking at these images (and others I didn't post) at full scan size, I'd say if anything the Ultron has very minor almost imperceptible barrel distortion, which is fine in my book. I can see the Cron ASPH's pincushion distortion without really even looking for it. Anyway, I will do a direct shootout with these lenses, so we can see for sure.

can you show me some examples of cron asph pincushion distortion? i can't see it in my images, and i'm not finding any examples on flickr that really show it.

Raid, no, it seems the names are speed related, generally as with Leica lenses. But some modern Heliars' construction are true to the historical name. (like the 50 f/2 and f/3.5 but the 75 f/2.5 Heliar is a Planar-pattern while the 75 f/1.8 Heliar is akin to the old Leica 73mm f/1.9 Hektor) Ah, well...

Pretty sure the names of most modern CV lenses refer to speed rather than design.

'Nokton' - faster than f1.5
'Ultron' - ~f2
'Color Skopar' - slower than f2

Here's one (4th photo). I'll post some direct comparison shots with the Ultron later.

thank you, yes i see the slight inwards bow at the edges. i suppose i'm one of the few that prefers slight pincushion to slight barrel.

i imported your Nikkor 35/1.8 and 35 asph images into lightroom. to bring both to zero distortion, where they are nearly indistinguishable from one another, i dialed in +2 for 35/1.8 and -1 for the summicron asph. i'd say that's an excellent performance from both lenses.

I have to say this looks really promising so far. Thanks for getting these up so quickly Jon! Bokeh looks to have a little swirl (which I happen to like) and neutralises very quickly as it's stopped down. Looking forward to the comparo with the cron ASPH.

Strangely enough, the pincushion distortion varies with the focus distance, so it looks obvious in some images and not so bad in others. IIRC Ken Rockwell covers it in his review of the lens.

Totally agree, Gavin. I quite like the swirl too.

Yes, a very, very tiny little bit of pincushion-distortion often looks more straight than 100% straight. Barrel distortion always looks plump.
