I'm thinking about buying a 28mm. I had the v2 Elmarit and previously had a v1 but really never cared for the lenses. I felt the v2 was good but not a show stopper and the v1 was only fair at best. I'm now thinking of the CV 1.9 or the Biogon. I have 2 Biogons in 35 and 25 and a 35 1.2 Nokton. All are just geat and can't make my mind up. The optics of both brands are very fine and the build of my Nokton is first rate. I would even put it above some Leitz lenses of later vintage. The CV is a little more than half the price with a little more than a full stop of speed gain. What are yoyr thoughts and how does the CV ferform at 1.9?

As always, I appreciate and value your opinions!
 
Hm, I don't know if I shot the CV at 1.9 but it is a great lens. My favorite on my Bessa T. I just developed some film, the negs are curled but let me see if any will scan well. If they lay flat for me (I press my negs under books for a couple days before scanning). I will post what I have. Todd Hanz has some CV Ultron shots in his gallery too. I will never show what this lens can do as much as he has.
 
I agree with Ralph, I've seen Todd make this lens shine. Also check out Regit Young's Pbase and RFF gallery.

Well built, incredible bokeh wide open. Never used the ZM 28, so can't offer a comparison.
 
Build quality is great on this lens too. I am glad to hear your praise of the 35 Nokton, I suspect the 28 Ulton is of the same quality.
 
Thanks for the tip on the two galleries. Both have some very fine work. The more I look at members work the more I love this forum. There are some truly tallented folks here that need to be hanging their work in galleries and museums.

From everything I've heard and my personal experience with the 35 1.2 and my 25 S mount for my Nikon the CV lenses are more than a bargain. The build is excellent on both of mine and both are very fine performers. While I like Leitz and Zeiss glass i don't feel they have the market cornered on quality and don't feel quality is directly connected to price. That's one of the reasons I purchased the Nokton over the asph summilux 35. Over the decades of shooting M's I've owned about thirty five Leitz lenses of relatively current vintage or new and more than twice that in Nikkor, Zeiss and Canon glass. I'm not ashamed to say that each manufacturer make fine lenses with each making some lenses better than others but none have the market totally cornered in quality. Each maker has focal lengths they do better than anyone else but ones that aren't as good as others.

I hope you get a chance to scan some of your images and look forward to seeing them. The ultron is high on my list at the moment.

I'm planning to do a little side by side of the three 35's that i have, Biogon, v4 summicron and Nokton, and i think I will throw in my 35 2.5 S nikkor, 35 2.8 f nikkor, and canon 34 1.4L. I did a little test about a year ago with my 35 1.4 canon L and my 1960's vintage Nikkot F mount. I have a Nikon to Canon adapter and shot them on my 1DsmkII. I also compared the 24 1.4 L, 24 2.8 1960's f nikkor, and 105 nikkor with my 85 1.2 L. I was absolutely amazes when enlarging the raw file to 100% how the Nikkors compared. F stop to F stop the 1st genration Nikkors were as sharp with much less chromatic aberations than the new canon L glass. The contrast was slightly lower on the Nikkor due to old coatings but the resolution and aberations beat the Canon. The 105 was truly amazing in that it was about as sharp wide open as it was stopped down. The test confirmed my impression of Nikon glass back in the 60's. I always felt the 24 and 105 were the tops money could buy.

It might be a couple of weeks before I can run the test. October is the busiest month in the studio and I've been working eighty hours a week.

Don,
the VC 28 Ultron is very similar in build to your Nokton, just smaller, they are almost identical in appearance. The hood attaches a little differently but that's about it. Wide open it has a pleasing bokeh with pretty good snap to the focused portion of the image.

here's one wide open: http://www.rangefinderforum.com/photopost/showphoto.php?photo=31159&cat=500&ppuser=489

I've seen some razor sharp pics coming from the ZM 28/2.8, see this one and the his others:

Looking forward to your side-by-sides of the lenses as I'm in the market for a 35 😉.

good luck choosing,
Todd
 
I've owned both lenses, and I just posted my thoughts about both in what I realized should have probably been this thread. Anyway, you can find my thoughts in the thread: "That CV 28mm f1.9 looks mighy nice" Page 5. post #43
