Zeiss PCDistagon

Hi,
Does anyone know of a source of information on how to use this lens. I recently acquired one at a modest cost and want to explore architectural photography (I live in London and there is an abundance of material). There are a few areas I'm unsure about and any pointers would be v.much appreciated.
1. In the Zeiss pdf it says "TTL Metering in Stopped Down Position". The pdf for the 100mm/2.8 macro says "TTL Metering at full aperture OR in stopped down position". Does this mean I cant use TTL on the PC-D at full aperture?

2. The reading in the view finder always displays 2.8 even at different apertures. This is the case when the lens is mounted on an Aria or RTSIII. Why is this and is it related to point 1.

3. Also on the PC-D pdf it states "the exact shutter speed must be set while the lens is in its normal (ie non-shifted) position." Does this imply I should not be using aperture priority but fully manual mode.

Any help would be appreciated.

Stuart,
you have indeed to manually stop down the lens, if you want to use AE (there is no AV- or P-mode possible, as there is no mechanical connection that allows the camera to move the aperture blades of the lens). The other way would be to do the metering with open aperture and then to calculate the appropriate combination and set it manually, as you would do with an external exposure meter.
If you want to take pictures with the lens in a shift position, you have to stop down to f8 or f11 for the extreme position. This is because then you are mainly using the optically critical outer parts of the image field. Also, if the lens is shifted, the internal exposure meter of the camera does not work properly because of the shift in the system's optical axis. So be shure to check exposure first, use AE-lock or dial it in manually, and then shift the lens.
It takes a little bit of practice, but you will end up with great pictures!
Good luck,
Marc

Sorry,
of course I meant "there is no Tv- or P-mode possible", as the only way to get auto-exposure with this combination is aperture-priority (Av).

And, Stuart, of course you can use the lens with TTL-metering (if it's not shifted) at f 2,8. But if you want to make use of it's shift capacity I would strongly recommend to step down.
And, BTW, the missing mechanical connection is also the reason why the camera's viewfinder cannot display the real aperture if it's stepped down.
Hope that helps,
Marc

Marc, thank you very much for that advice. It is a great help. I'm quite excited about using the lens and your advice will certainly save me alot of duff exposures.

How is this lens opitcally? Is this lens worth the money contax is asking for?
How do you rate it. I viewed the MTF but I like to get some personal data.

Thanks,

Several years ago, when the dollar was strong, I purchased a Schneider 28mm PC with a Contax mount from Fotohobby in Frankfurt installed at the factory. This is the real deal, not some Mickey-mouse adapter add-on. It is the same lens sold for the Leica R system and a superb lens. Check it out on Photodo. I paid much less than I would have for the Zeiss. I am about to trade it for some digital stuff, but would be interested in selling it at a reasonable price. I would need to hear from you soon.

stan,
Thanks for your offer. The lens looks great, the only reason I asked about the pc was because I was getting a good offer on it. I actually want to use it on my canon digital system.

Now having said that, let me know if you have a 21/2.8, that I would want.

Thanks,

No, I don't have a 21mm for the SLR, just for G. By the way, you can convert the Schneider PA Curtagon to other mounts.

Stan,
thanks for your message. I got the 35/2.8 PC from BH. They were selling their demo unit for 1199. When they had it in stock, the sold the new one for about 2600. I figured the discount is not that bad and I should take a chance with this lens.

I am not a Jew but I've learned to love their culture..... B&H knows that very few folks will buy the 35 PC lens for $2600. There is probably an 'as new' minimum price they can sell it for.... so they turn some into demos and sell them to us... .. (My 85 2.8 was a demo).. B&H makes a sale... you get a good price... everybody happy.

John,

You really should be a bit more tactful with your expressions ...

"One of us is missing something here"

And that in fact would be me. After hearing them disparaged once too many times, and having a few as close friends, I came back trashed from work in a rush to go elsewhere, read the first few words of your message very closely obviously hardly glancing at the rest, and had a bad reaction.

Reading again in a more attentive manner revealed the error of my reaction, so please accept my sincerest apologies! I do need to lay back a bit ... maybe this long week-end.

Nevertheless I would like to point out that your Lutheren God is probably the same as my non-Lutheren God
.

God bless the Internet and illumine its denizens.

Going to get some rest

Hi DJ and John,

It so refreshing to see people loving each other the way God intended. Jesus loves you all.
