Voigtlander Ultron 35mm/1.7

Peter · 10-23-2004

Dear Fellow Ultron Users,

I have heard from my friends that the Ultron has construction defects that will result in the front ring coming loose in the most unexpected moment. Does anyone have similar experience.

Regards,
Peter

I have heard it occurs when adding and removing the hood and filters. The front assembly can unscrew itself.

Peter, what is your experience with the Ultron compared to your other 35s. I just got some shots back and I was very happy with the results. It produced very sharp images. On the same roll of film I had some shots from my 50 Summicron, the Ultron shots had a different character, but they were nice and sharp.

Peter · 10-24-2004

The Ultron is my favourite 35mm lens! It is like you say very sharp and very contrasty too! Some of my best shots are made with Ultron as evidenced by the photos in my member gallery.

I have heard the same thing about the front ring coming loose when changing filters but there are also users swearing by its excellent construction. Could it be a case of poor quality control? I am looking for another fast lens to complement the Ultron and I am looking at the Classic Nokton 40mm/1.4 very closely!

Me too regarding the 40, I have my fingers crossed that it will get some great reviews.

My scanning abilities were not with me yesterday, but here is an Ultron shot that just stuck out to me as very sharp when I was looking through some new prints. The scan doesn't do it justice.

It is on Kodak 400 TMY.

Peter · 10-24-2004

Sharp and contrasty! It does has the familiar Ultron look to it and you must be very glad to buy one. I do hope that the 40mm/1.4 will be up to our collective expectations, I will be very disappointed if it is mediocre lens! What about other CV 35mm lenses that you have used before?

Tim · 10-24-2004

hmmmmm.....wonder if I can use rumours of questionable quality control on the Ultron 35 to justify a Summicron 35 to the missus????

I've had no problems with my Ultron 35 at all. Love that lens, I bought it because I wanted the extra 1 1/2 stops from the Color-Skopar. Very happy with the results from both of them, but I think the Ultron has the definite edge.

It feels very good to handle, too. This is the first I've heard of problems with that lens, hope they aren't widespread...

Tim, the 35 Summicron has a wonderful character to it, I really like the look of images taken with it. Take a look at Todd Hanz gallery for a lot of great examples. The 4th version of the Summicron, the "King of Bokah" version, shares the same issue as the Ultron though. So, shop smart, and buy the Leica lens because you like the "look" of it, not because of a potential problem with the Ultron.

Peter, I haven't tried any other 35. I am tempted to find a CV Classic, you can get them for a low price now a days, but I keep getting good results back from the Ultron, so my desire isn't that great. I am looking forward to seeing some tests and results from the Zeiss 35/2. It is about the same size as the Ultron and from my handling of it the other day a wonderful feeling lens.

Peter · 10-24-2004

You know what Rover, you should be like Tim and have both the Ultron and the Color Skopar 35mm!

Well, after I've seen the results from Summilux 35 Asph (35/1.4), everything else looks rather.... ordinary

Man, but that thing sure IS expensive (found one used for 1,300 EUR - something like $1,5000).

...NO, I did not buy it!

But, I keep thinking about it every now and then - e.g. whenever a question of 35mm lens pops up

I have a CV 35/2.5 Pancake 1 and it is an excellent lens. Very short throw from infinity to close-up, terrific build quality (barrel and rings are brass). Color rendition is warm, it is sharp, and the OOF area is very nice at f2.5 (something you can't say about all the CV lenses). I love the lens!

back alley · 10-24-2004

i'm very happy with my cv classic .

as to the end of the lens unscrewing when taking off a filter - my 'new' canon 135 ltm does the same thing. i think it's part of how it's designed. brian may know more about this though.
i can see if you are REALLY NOT paying ANY attention at all how the front element might come undone. but then your white cane might stop the fall.

I just read some threads over at photo.net. Whenever someone mentions a 35mm lens, the 40mm C and CLE are brought up as better options. Makes you think......

Peter · 10-24-2004

Brian, if you are reading this thread, why some lenses come loose when you change the filter?

Hah, I've probably done that myself once or twice.

The 35–40mm range is my favorite with RF cameras. I have the CV Ultron and the Color Skopar II. Both first rate, with the modern sharp & contrasty look. Though strictly a matter of personal taste the best of the whole lot, IMO, is the 40mm Summicron-C. It's a high resolution lens with lower contrast than the CVs, though still high enough for snappy images, and bokeh at least as smooth as the acclaimed v4 35mm Summicron. It sees into the shadows real well. It and its Minolta Rokkor equivalent can also be had used at reasonable prices for a Leitz/Leica lens. Worth a try if you happen to come upon a used sample in good condition.

I think I would have to agree Dave
