Hi,

does anybody have a little bit information about this cameras?
Or better are there manuals available. Is the production period and the number of cameras known.
I think it will be also a good idea to open a new thread in "Contax bodies - manual focus"

thx for input

Hi Vini

Your thread title seems to mention two different cameras....have I misunderstood. Which camera or cameras do you wish to know about.

There are three Contax Preview variants and two CGCM camera variants that I know about.

Preveiws run from 1982 to 1995 and CGCM's are 137MD derivatives, post 1980, used in Agfa Matrix Slide Maker machines. I have photos of all cameras. What would you like to know?

Cheers, Bob.

CGCM - it's not 100% clear but it's probably Computer Graphics Camera Mechanism.....according to various sources!

These 137MD derivatives were part of a system made by Matrix (later Agfa-Matrix)for photographing the image on a computer monitor...for 35mm slide projection (or less likely...prints of the monitor image).

They were controlled and powered via a flying lead or attachable lead connected to the battery compartment (which is sealed off by a screw).The flash shoe, flash and shutter remote sockets are blanked off. There is a blanking plate over the viewfinder and on the CGCM I, the mirror is removed. The X, B and Auto switch is removed and the AE lock position is unusable.

Nicolas Grossman estimates that 2000 were made.





Move info available, cheers Bob.

Hi Bob,
thank you million times for your input.
I purchased both cameras. Now I know that my collection got new holes, because I have only one Preview.
If possible I want to all about this both cameras and about all other Contax cameras too.

Thanks again

bye

Hi Vini - glad to help!

For Preview pics have a look at:
Contax User Forum » Contax SLR C/Y-mount » Accessories for manual focus system » Preview Polaroid Camera.

I hope this link will work:

You might like this - when I've finished it - A2 chart, printable as 2 x A3 or 4 x A4 sheets. It's about 1MB as a jpg. A bit more work to do on it yet!! Here's a little preview.

Now, this'll give your collecting plans a headache!

Cheers, Bob.

Hi Bob,

I thought I'm crazy about Contax.
My wife is jealous of mz Contaxes.
It's good to show her that I'm crazy
but others are mad.
Bob please send me this tree in fullformat.
Maybe you have some missing items and I can
help you.
I like your work very much and it seems that
I can throw my Excelsheet to the moon.

The headache wouldn't be so great, it will take only a little bit more time and of course more money.

Bye

Vini

... If Bob want to, we can upload this Contax tree in the scan section. If yes, please send us the file as jpeg (no PDF file) and we can upload it then there.

Hi Vini

Sure - *contaxcrazy*, I admit! Also a little Yashica crazy too! There's a Yashica chart in progress too!

You can send me your email to bobbl@bluecontaxcrazyyonder.co.uk ...remove the bits between the **'s

The chart is incomplete and in the process of being checked for correct data. PLEASE do not pass it on to others yet - I'll do that when it's finished! If you can help by adding/correcting data that'l1 be great! You also have to agree not to make any profit out of this...as I have also promised the dozens of people who let me use their images to create the chart that no profit will ever be made from this project.

Don't throw your spreadsheet away just yet...I might need it! Hee! Hee!

Will your ISP allow 1MB jpg's?

Cheers, Bob.

Hi Dirk

....early days yet... too soon to post anywhere in public. There a few people looking at it to look for omissions/corrections etc.

If you want to help ...I'll post it privately to you. But see previous post to Vini for conditions. I'm sure you'll understand.

The Contax Postal Club (UK) will have it's own website in the near future and that is the intended "source" for the Contax and Yashica charts. Here, I will be able to control updates easily.

Some ISP's bounce 1MB mailings. Send me a suitable mail address and your confimation of agreement to conditions, if you would like to see the big'un.

Cheers, Bob.

Hi Bob,

That chart will be something to behold when finished. I am sure we would all like a look.

I was just wondering whether anyone was using the MIR Contax site. It has a lot of very well done information and history.

I know that at one time he was looking for someone to take over the Contax section. I didn't feel I had a broad enough background to do the site justice. Also, I think Leonard had some copyright concerns and threats from Contax regarding the wonderfully detailed information on that site.

Hi Don
yes - I've seen it - a nice site.

It's a shame if he has had copyright problems form Kyocera.....because I've had great co-operation from Kyocera Yashica UK's Contax Manager, Frazer Allen. He gave me permission and supplied with a CDROM of images.

The older cameras' images I had to scrounge around the world for....and had lots of fun using Babelfish to converse with many people in many languages, who gave 100% unreserved help(except, naturally, a no-profit condition)! I can only remember one person out of dozens and dozens I emailed who did not reply. Naturally, I've kept all permission emails to narrow down the chance of copyright problems!

Sometimes I needed to add a Babelfish translation in their own language before they replied.... and I regarded that as fair game, as I can't read Japanese, German, Italian, Swedish etc. , either!

People photographed their own cameras for me, supplied prints for me to scan and allowed me to copy their images from their websites. Their in-depth knowledge of individual and groups of cameras was an incredible help (I am still in discussion over dates and oddments with them). I am in great debt to them....the charts would not have been possible without them.

The Contax Yashica people are the friendliest camera people in the world....I make that official :) (let's see if the smiley face works!)

Cheers, Bob.
