Any Linhof Technorama 617 S users here?

A couple of questions for you:

What is the filter factor for the Schneider Center-Filter IV? It looks like it is approximately 1 stop or possibly 1.5 stops.

While testing will be done, in general how accurate are the distance and hyperfocal near/far scale markings?

Is there a lens hood available t ofit the Schneider Center-Filter IV that will not vignette the image?

Finally, is there a digital back available for this camera? (just joking!)

Thanks!

Robert White has a chart with the Schneider CF filter factors, and IV is listed as 1.5 stops--

105mm front thread, eh. Maybe there's a B+W rubber wideangle hood in that size, but it would be nice if there were a rectangular pano-format hood for 6x17.

Thanks David!

The distance scale is as accurate as it can be. No problem there. The same for the hyperfocal depth of focus scale. You can easily see it for yourself with a test - put a ground glass (even a paper replacement) on the film path and try it with measured distances. A lens hood cannot be too deep though (I have a home made one).

No lenshood that is commercially available will work on a Technorama with the 90 or the 72mm lens without vignetting. This includes the Heliopan 2 position 105mm hood in the wide angle position.

Thanks George and Bob!
time for the ole baseball cap trick I think.

Ellis, forget the hat trick. I just measured my computer calculated lens shade for the 90mm Schneider I have with the 617S. The inner rectangular dimension of the lens shade is exactly 137 x 49 mm. The depth of the lens shade is 25 mm and it sits on a filter rim ( 82mm diameter UV filter, I took away the glass). And yes, the lens shade covers partially the lens diameter - it is because the film uses just a part of the image circle, of course.

You can try the Lee filter company for custom hoods and filter sizes. The made a 108mm filter holder for me a few years ago to go over the outer diamater (105mm) of the CF on the 90mm SA on my 617s.

Ellis,
I bet Josef Koudelka didn't prance around Eastern Europe with his Technorama 617 and some prissy hood system.

Real men use their hand. That's what I do...
