Old/new 35mm Ultron comparison?

There's a nice picture on the Head Bartender's website (scroll down to the 35/1.7): https://www.cameraquest.com/voigtlen.htm

Oh dear. That lens completely overpowers the poor Barnack 😉

I could live with the size of it, but not at the lens mount end. Guess I'll have to look for another fast, modern 35 for my little Barnack. In time, first it needs a service.
 
I have a huge collection of 35mm lenses, but this one is the best. Sharp until the extreme edges and no distortion. It draws enormous contrasty scenes in one picture without problems, see the shot in the train.

Erik.

I would be interested in specific lenses you own and have determined to be inferior when compared with the Ultron.
 
It looks to be a very nice lens. But most pics I see so far are stopped down and reality is - most modern lenses will perform well. Also, so far (just like with the CV 50/1.5) I really dont see a reason to upgrade from the LTM version. It may be a little sharper, a little more flare resistant, but it's also larger and more expensive. Oh, and before you say that new one focuses closer - I made my CV 50/1.5 and 35/1.7 LTMs focus down to about .5m a long time ago - not a difficult fix.
I would really like to see more pictures that compare the new Ultron with the LTM one - maybe I just didnt see enough photos to be able to justify the upgrade. Cause if I really want to larger and better lens - I have 35/1.2.
Maybe I'm not seeing something, but I'm not sold on this one yet.
 
Oh I agree - its a very nice lens. I just think Cosina did us all a huge favor back in a day (while shooting itself in a foot) - designed and made truly superb lenses at very much bargain prices. And now it's hard for them to recover and make something thats significantly better so it would justify the price increase. I love my older CV lenses and dont plan on parting with most of them as I know that I will have to pay a good amount more to get the same thing in a newer versions.
But yes - these new lenses look to be very nice - we just got spoiled by the original/early CV lenses from a few years ago.

How easy is it to convert the LTM to close focus? I really like my 35 Ultron LTM but I hate the .9M close focus.

Well, if you have worked on lenses before - it's not that hard. Here is a thread I posted a long time ago - about converting CV 50/1.5 ltm to focus closer. Ultron 35/1.7 LTM is similar:

Look at it and see for yourself if this is something you want to try.
 
I know quite a lot of people with Mac computers, and these have indeed darker screens. But what is right? I don't like those dark screens.

Damn our computer/internet infrastructure that creates these differences.

Erik, thanks for your comment that you don't like the darker Mac screens. This may be a hint. I just looked at this thread on my Mac and on a current Windows machine.

For what it's worth
- Erik's photos appear darker on my mac screen than on the PC.
- Differences are subtle, but there.
- For example, I cannot see the spider web on my Mac, but I saw it immediately on the PC.
- Other's photos appear the same on both, e.g. Robert's B&W and Lawrence's color.

I note Erik's are RGB with no profile, Robert's have the sRGB profile. I don't know enough to take this further.

This ought to be easier.

The images are terrific, and the lens looks very good. Thanks for posting.
 
Ultron ASPH vs Summicron ASPH (the old version)

Ultron ASPH vs Summicron ASPH (the old version)

I have both this lens and the Summicron ASPH (the older one, not the latest release). The Summicron is far more compact, but dense. The overall weight differences are not as great as they would visually appear to be, as a result. However, if you add the dedicated hood for each lens, the Ultron is far bulkier in appearance.

Still, I wonder if the Summicron is worth $1500+ more. I tend to doubt it though, as the images from both are indistinguishable if I don't put cards in the image stating which lens took what picture. Also, the Ultron gives you the extra half stop for when you need the extra speed. If I had to do it again, I would not have bought the Summicron ASPH.

High praise indeed. This is definitely on my short list of potential future buys, so nice to see a reasonably priced well made fast 35 in M mount that is decent, even when wide open. Love the chrome version too.
 
Roland,
How much focus shift do you see at various aperture values?

Thanks,
Alan

Hi Alan,

very little. I just did this test shot (around 0.7m focus distance):

ShiftComp-f1.7-XL.jpg


And comparing f1.7, 2.0, 2.8, 4.0 and 5.6 (click for larger size):

Roland.
 
Nice, Roland. For my film use, seems like I don't have to worry about focus shifting at all.

I am loving the Nokton-M so much I feel this new Ultron could well be my next step.

I could totally imagine my Elmar and Summaron as day-time walkabout combo and Nokton and Ultron for night and indoor specialist.

Yes, and it can be a lot cheaper to have VC glass for a night time set than to buy fast Leica. I think this might be my approach in the future also, a Summaron is my choice of daytime walking around 'main' lens as well.

Thanks, Sug. Pretty much what I'll be doing, except for Elmar-M + Summaron, or Nokton 1.1 + 1.7 Ultron.
