Zeiss 25mm f2.8 Distagon discontinued

G

Guest

In anticipation of the Contax sales days this week (June 6, 7 & 8), I called Adorama and B&H in New York to see if they had this manual focus lens in stock. They both said that it was discontinued! What does this mean? Is this an indicator that Contax/Kyocera is in the process of phasing out manual focus lenses and cameras? Is this happening with other lenses in the manual focus line? A couple of weeks ago someone on another camera user group reported that Contax was planning to phase out its manual camera and lens line -- have others heard this rumor?

Hi Dennis,

the only thing I heard is, that as long as there is enough demand for manual focus, the lenses and bodies will be also produced in the future. But there will be no new lens design or body for the manual focus system.

The future is and will be the N-system. If you look at it closely, Contax seems to have made already in the late 90s the decision to go for three new different camera-system all with one new lens mount. This is the Medium Format 645, The analog N1/Nx and the N-digital.

I could imagine that as soon as the demand drops more over the time for the manual focus system, one lens/body after the other is fading out. As long as there are still items in stock, you can buy it still new.

The market is not big enough for Contax, to offer a self-competing 135 system on the market. The ability of using manual focus also with the N-system is therefore excellent made.

Contax has so many choices for the consumer. More then 3x as i.e. Leica.

You can also have a look in the folder "which Contax system for your needs", to get a better comparison.

Can you tell me more about this Contax SALES this week (June 6-8 ?) Personally I am planning to get a T3, being convinced from reading the review in the June issue of Amateur Photography. Thanks !

It is easier to answer this in the specific folders in this Forum...

The sales from June 6-8 seems to be restricted to the US only. In Germany we have different dates with each Contax shop.

You can look in the "events" folder to get more detailed information or go to the Contax US webpage.

For a detailed review of the T3 you can have a look to my review in the Contax Camera folder.

Unfortunately, I have not read yet the article in AP, but even if it is positive for Contax, I would be always cautious with reviews and try to test the camera yourself before buying it...

See for this my comments of different tests of Contax N system.

Nevertheless I like my T3 a lot

Bill,
Yes, Dirk is correct. The sales days were announced by Contax USA. Their website indicates the dealers who participate. As I understand it, some excellent dealers ship internationally but I'm not sure whether the costs of shipping and any import duties would offset the 10% savings. I can, however, recommend B & H Photo and Video in New York. They offer the best prices and the best service (they have an excellent website).

Dirk,
Thanks for your comments regarding my original message. I am intrigued by your statement that
"The ability of using manual focus also with the N-system is therefore excellent made." I was not aware that the manual focus lenses could be used with the new Contax autofocus cameras. Would you explain this? Is a special adapter or are modifications to the manual focus lenses necessary? Thanks in advance for your response.

Sorry, this was a misunderstanding. There is no possibility to connect the lenses of the old C/Y mount on the new N-mount.

What I meant with "using manual focus in an excellent way" was just the handling of the new N-lenses in the manual focus mode. With the dual focus mechanism, it is extremely comfortable to switch between AF and MF. Also the way how much you have to turn the N-lens and with how much effort to focus manually is designed perfectly.

You do not have this kind of wabbling feeling what you might have experienced with other AF brands while using it in manual focus mode. Just try it at your photo-store.

the news(or rumour) about the new RX model is a delight. it might mean another lease of life for manual contax cameras..for now..and maybe they cant deny that their existence was borne of that aging quality metals..new glass coating technology created those auto n-lenses, why not do it with manual? imagine new T** lenses..just a wish. btw, nice site dirk.

I think everybody hopes this, but in the moment I do see only announcements of discontinuation and not of new C/Y lenses


the 25/2.8 and the 35-70 is running out. I do not mind for the 35-70, but the 25 is a very important lens for me.

Hopefully Zeiss is bringing the N24-85 also with a C/Y mount. This would be a homerun!

Dirk, I agree that a 24-85 CY mount would be terrific. Do you have any information about the possibility of such a lens?

CZ Distagon 25mm f2.8 and vignetting

Could I ask those of you who have any experience with this lens how you've managed to bypass the problem of vignetting?

With a standard Hoya filter, at open and mid-apertures, I've noticed a light-fall out which is more appreciable at the fastest aperture. I've abandoned using a 67mm Cokin system which gets included in the photograph and tried the 82mm step up. The vignetting is still there.

At open aperture, I've not been able to work the lens to produce pristine eagle-eyed images either. This doesn't seem to creep in until f5.6 - f8, noticeable on projection. I've been wondering why I bother with a lens which has three usable apertures, and has a tremendous light-trade-off at the corners.

Hi Joe,

I used to use this lens a lot for landscapes, and must confess I don't recall vignetting/light fall-off problems. But to be honest, I also don't recall being terribly vigilant either, just never noticed it (except when stacking filters). I frequently used a polarizing filter and rubber lens shade combination, both 55mm, with success. However, I seldom shot wide open, usually going for max DOF.

I understand that in general, the Distagons have pretty good light fall-off characteristics, less prone than, say, the Biogons.

> Hi, I use the distagon very often and do not have the problem you mention. I use a 67mm-Polarizer with an 55to67-adapter and the vignetting is no more than without the filter. Also without the filter vignetting is not a great problem. I often use the lens at f4 and never worried about vignetting.

that won't help you very much ? matthias

I have not yet tried this lens, I just bought one. However I have been using a CZJ 28mm lens for some time and I use the Lee filter system with a wide angle adapter. The wide angle adapter attatches the filter holder very close to the front of the lens, the Lee Filters are also much wider than the Cokin Filters so vignetting should not be a problem. If we dont have more filthy grey weather this weekend I'll try out the Lee Filters on the D25/2.8.

This sounds quite bad! I wonder if the Yashica ML 24/2.8 is any better, they seem to fetch very high prices on ebay. I have heard that the D25/2.8 is a bit soft wide open, but I figured as long as I can get sharp results in the F5.6 - F16 range then it will do until I can get my mitts on a D21/2.8!! Light fall off in the corners though will upset me if this occurs at the middle to small apertures!

Anyway, I will let you know of my experiences with this lens once I get some slides back.

Cheers,

Art.

I inhereted this lens from my father 13 years ago. He had it at least since the late 70'<font color="ff0000">•<font color="ff0000">•<font color="ff0000">•<font color="ff0000">•<font color="ff0000">•<font color="ff0000">•<font color="ff0000">•<font color="ff0000">•<font color="ff0000">• a very fine lens. I have experienced vignetting only once when I put a lens hood made for my 50mm on it. other than that one occasion I have never had a vignetting problem --and I use filters with this and all my lenses. I never heard my father complain about this problem either. He, like me, loved this lens. It is tack sharp & gives great color rendition. So in short I have never had a problem with this lens.

Thanks for commenting on the lens.

I was impressed (on paper) by the luminance characteristics, however my MTF skills may make me think twice about buying a lens on that criterion alone, or on the basis of the focal length.

The kind of vignetting which i experience is a little like a Black & White photographer, trying to do a partial burning-in of a bland sky, and achieving a subtle vignette. The fall-out looks dreadful in contrasty situations. It was at its worse using a square Cokin A with a black inset to hold the coloured resin. This fall-out is apparent in most of my 25mm slides projected on the wall. I thought it might be the projector, but I don't have a lupe to know the difference.

Mathias, I guess you're using a circular polariser, whereas my Cokin square holder gets in the corners, especially the third filter slot. It's really annoying because I have a wonderful yellow-blue polariser which only comes in square format; my circular polariser is just a plain ol' polariser.

Yes, you are right; my polarizer is a circular one. But I also sometimes use Cokin P (!!) filters, where I don´t see any unexpected vignetting. Cokin A seems to be too small; I bought the Cokin P instead of the Cokin A because I was afraid of vignetting with the 25mm !

Interesting posts here that actually fit to what my experiences with the 25/2,8 are. I found one in very good condition for a reasonable price but I was dissapointed to have vignetting wide open. I sold the lens some months later again and got back what I invested. Dont know why the reputation of the lens is good. IMO there are some bad and some good pieces out there as some of you are satisfied with this lens.

Maybe the Contax lenses, being the result of modern German and/or Japanese = production technology, are somewhat consistent and uniform in all aspects, = wheras the photographers that use them might have differing views and opini= ons about what they see through the lenses. And how they use them.
