Looking for lens in shutter that won't cover 4x5

[Michael S. Briggs]

I expect that any 100 to 105 mm Tessar-type lens will produce images that are soft in the corners of a 4x5 film. I did some tests on 4x5 of a 105 mm f3.5 Nikkor-M -- my results are described at http://www.largeformatphotography.in...ic/494534.html. The 105 mm Nikkor-M lens is close to rare, but I think the results are characteristic of the Tessar design, so other more common Tessar-type lenses should give similar results.

I use a 100mm Sironar N for 4x5 at infinity all the time. When using no movements, only the faintest sign that coverage is running out is visible in the corners, so I expect you need to go with something with less coverage for what you want.

Zeiss TEssars never seem to fail in their ability to fall short of coverage and they give you the bonus of softening extremities, thankfully this extends only to the film and not the user.

I was wondering what the new film called Viagrachrome was for.

Thanks for a good laugh Andrew!

I ordered a 105mm Zeiss Tessar from Brooklyn Camera Exchange after considering everyone's advice. I will let you know if the softening of the extremities does extend to the user!

Michael's idea about using filters to vignette is something I am going to pursue. I've worked under such a strick "no vignetting" construct for so long that things like that just don't occur to me.....

thanks again for all your help.

The 105mm f4.5 Zeiss Tessar arrived. Clean but no cable relase socket, have to trip the thing with my finger. No way to keep the lens open to focus other than to wrap a rubber band around the shutter to hold the relase down. But that's ok....

Now the bad news. Despite the fact that literature I read on the lens says it produces a 130mm image circle, the damn thing covers wide open... go figure....

I acquired a Kodak 75mm lens last night in an Alpax shutter (a lens for an oscilloscope I think). Works fine but no retaining ring. I taped it into a cardboard lensboard and it definitely does NOT cover, not quite a full circle. Not sure what the optical fall off will look like on film.....

A 4.5/105 Heliar?

A 105mm Rodenstock Trinar fits the bill perfectly.

Did anyone notice the date that this post originated?

Steve Williams located the lens he was seeking six years ago.

BTW, a Nikkor f5.6 105W will also fit the bill very nicely.

I wanted a circle on 4x5 and bought a 4x4 Yashica and took it apart, mounted the lens on a recessed board I made from black foam core. The lens didn't have a cable release socket so I from Steve Grimes and epoxied it to the board. He thought I was crazy BTW, why a circle??? This was mounted on a Speed Graphic that the front hinge had broken, worked well, looked great with Kodak 4x5 Infrared.
