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.

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.

Roland,
How much focus shift do you see at various aperture values?

Thanks,

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.

Hi Alan,

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



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

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 Roland. I think that looks minimal enough to make the 35/1.7 my one M film lens.

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

Beer and Sushi at 4:45am; my co-worker Zhong


And when you don't have anything wider - just do a panorama (4 Ultron shots)

Nice shots Roland. Looks like you are enjoying the short visit to Japan. Wish one day soon I'll be able to go visit the Tsukiji market and have some early morning sushi.

Thanks, Gabor, Erik and Sug. Gabor, hope to meet you next time. Sug, Tsukiji will be moved later this year, not sure if it will be still accessible afterwards.

A couple more that show how nice of a background the lens renders when you have to use it wide open:

Pro for the new Ultron: no distortion, smaller. Con: one stop difference.

For film, I would probably prefer your lens, Peter. On the 240, speed is less important, IMO.

Thanks, Roland. Yes, I agree, the 1.2/35 shows a bit of distortion and is hefty but so am I ;-)

On Flickr, I like a lot some photographs by Jim Delcid with the old ltm Ultron 35/1.7.
I suggest it as a source of examples of the old ltm Ultron. (great Planar 50 ZM "examples" too from Jim)

Also interested to see the new Ultron on film

My Ultron-M 35mm f/1.7 is on its way to Germany and maybe it will later travel to Japan. Cause? The Wobble. The Wobble started barely perceptible, but grew worse and worse. None of my other CV lenses ever showed a wobble. It seemed that the whole front group came loose.

Nice pictures, Roland. Unfortunately I haven't used my lens the past two months. It started do develop a "wobble". I have a repair under warranty. The lens is send to Japan as Ring-Photo in Germany - the European importer - does not touch lenses under warranty.

Thanks for sharing, Ferider. I never seen California wild life side, even if I have been in CA a number of times. I, like you, ride and I go camping a lot to the the Boundary Canoe Area here in Minnesota, but unlike you, I am shy about posting my pics. I have been enjoying your posts for a long time, starting with your experimentation with Roninal (3ml) way back when. I admire your work and willingness to share your efforts.
Thanks again,

Grazie mille, Giorgio, your post made my day ! One day, I will make it to Minnesota in winter, for landscapes, it's on my bucket list. If you ever come by the Bay Area, let me know, I always have a spare ride.

Have to get back to Rodinal !

The wobble, ominous sounding. Is there a prophylactic servicing for the wobble? My Ultron needs collimation - probably because the previous owner repaired the wobble and put it back together incorrectly.

The Ultron-M is back home, after two months, and is now excellent. However, in the meantime, I've got a Summilux 35mm f/1.4 v1. This lens is much smaller and more convenient in use, is not better than the Ultron-M, but has a very attractive rendering. So the Ultron-M stays home for the most of the time.

The M Ultron is about as flare resistant than any lens I have ever used. Even bright neon tubing holds up well! This is a shot from Ford's Dearborn Village.

I've bought one after I sold my Summicron 35 V4 to pay for the M9.
I have to admit that lens really performs! BUT I just don't like using it very much. I don't like that the close focus is closer than the RF coupling (I know that is important for all the adapter crazy folks) and I really don't like the focus ring. I would prefer a more standard solution over that gear wheel which I find uncomfortable. I also keep missing it and rather grab the aperture ring instead (that might just be a getting used to problem).
All in all I prefer my Summicron-C 40 over it (also size-wise) although the Ultron definitely is the better performer.
