Focus tab may be metal but it’s probably not brass. Only the body is brass. look at this worn out Skopar. Everything looks brassed except the focus tab (and the hood?). It’s like ours.

The Ultron tab's paint looks like it's completely pealing off once it's chipped, which is either due to lack of surface prep, inferior paint formula, or both.

You are correct, it will just advance with slightest friction. Could be any or both. Cosina acknowledged it under warranty yet I wonder if it will happen again once I get it back.

madNbad Posted November 6, 2022 Share #285 Â Posted November 6, 2022 It't probably aluminum. I have the 35 Ultron V2 in the silver finish and the tab is not the same material as the lens body. Quote Link to post Share on other sites More sharing options...

If not, they will need to come up with a fix. Quote Link to post Share on other sites More sharing options...

Ponnefaxen Posted November 25, 2022 Share #289  Posted November 25, 2022 Debating between this 28 Ultron and 28 Elmarit v2. Looking for something smaller and a tad wider to complement my 35 lux.  Anyone who has used both and can tell me how much bigger the Ultron is?  And any other opinions from people who has used both would be appreciated!

MikeMyers Posted November 25, 2022 Share #290 Â Posted November 25, 2022 If it matters, there is a huge difference in selling price. Lots of reviews on both lenses, for making a comparison choice. Quote Link to post Share on other sites More sharing options...

The vignetting at f/4 is about the same if not a little less than the Summicron 28mm ASPH II. This image either cannot be f/4 or the vignette was added in post. The Ultron just vignettes objectionably at f/2. Even at f/2.8 it's a lot better. Quote Link to post Share on other sites More sharing options...

lct Posted November 27, 2022 Share #295 Â Posted November 27, 2022 On real world photos i can't seem to see differences between Summicron 28/2 v2 and Ultron 28/2 asph v1 re vignetting at f/4. Comparisons are not very easy though as the actual focal length of the Ultron is slightly longer than that of the Summicron which FoV is a bit wider accordingly. F2 is another story as mentioned above but the Ultron is significantly smaller. Quote Link to post Share on other sites More sharing options...

F2 is another story as mentioned above but the Ultron is significantly smaller. I am referring to Ultron II, not the first version. That said, while the difference is there, it is not a big one. I had both lenses at the same time and put a thin, white piece of plastic on the lenses (using an adapter ring) and took test shots in a very evenly lit condition, so I can confidently say that the less vignetting is real. See the results here: https://drive.google.com/file/d/17lD1EHQUpqPKRzU1hHIbNhlCpNGjI32w/view?usp=share_link Whether that is of importance in practical use is another matter. However, since the Ultron II has clearly more optical vignetting than the Summicron Asph II (both) shot wide open, I think it is worth noting that this disadvantage changes to a slight advantage at f/4 and f/5.6. I speculate that the Ultron II has a longer exit pupil than the 'cron. Edited November 29, 2022 by LarsHP Quote Link to post Share on other sites More sharing options...
