Carl Zeiss 300mm f5.6 for 8x10 Photography?

[lightcat]

Does anyone know the image size for this lens? Besides the lack of aperture and shutter (which is fine by me) is this lens suitable for 8x10 photography?
Thanks.

Hi Lightcat

What lens design are you talking? Is it a late Tessar?

The design has everything to do w/ coverage.

If it's the 300 Tessar f5.6. it should cover w/ a little room for movements.

The best way to tell is to put the lens on a 8x10 camera & check it out.

Peace

Hi Louis, thanks! You guessed it, it's the Zeiss S-Tessar 300mm f5.6 -

Any idea where I might be able to get a 76mm or 77mm retaining ring to mount the lens on a board?

Does this lens have a shutter? or an aperture? Google reports suggest this lens was made for use in photocopiers near 1:1. You might want to cobble it onto a foamcore or cardboard lens board and see what kind of image it makes before you invest, even in a flange.

I have no idea what the coverage is of that lens, but be aware the Zeiss S-Tessar was designed as a copier lens. These have been floating around for years, at very cheap prices, but they are in a solid barrel that can't be easily adapted to using an aperture diaphragm, or even waterhouse stops. Coverage is also probably limited by the mechanical design and inability to stop down.

Do yourself a favor, and at least get a real barrel mount 300mm f4.5 Tessar with a working aperture diaphragm that was designed to be used as a taking lens. They are plentiful on eBay at very reasonable prices and offer outstanding optical and mechanical construction. Other than the lack of a shutter, these are excellent general purpose taking lenses of very high quality and a real bargain. Look for a late coated sample with a 4 or 5 digit serial number.

Thanks for all the info everybody.

Wow - $129 for a mounting flange at B&H! Seems like I could have one made locally for half that at most.

@ Kerry - If I don't need to stop down and am shooting with strobes, so no shutter is needed, what are the disadvantage of a copy lens as opposed to a taking lens. Don't copy lenses have good flat-field coverage and sharp optics?

I'm going to pop the lens on for a quick test. I'll report back in the next day or so.

-Thanks all-

Something else to play with on that lens. If you unscrew the front it works like a Wolly Velostigmat with diffusion.

I'll have to try that some time. What's a Wolly Velostigmat?

Velostigmat Series II was Wollensak's flagship Tessar type. Some of them had a front ring on a thread that allowed the space between element #1 and #2 to increase thereby introducing some diffusion on purpose which can be useful for portraits.
