Lens Question

**Tony Baker** · 18-Oct-2009, 19:31

I have a Cambo 4X5 rail camera with a Caltar type S 135mm lens. I really want to go to a field camera because the rail camera is so big and bulky. My question is can my lens work on any 4x5 field camera as long as I have the right lens board. If I can use this lens it would be great because it looks like it will save me a lot of $$$$$! Really been looking at a Wista.

Thanks for the help!

Yup, if it works on one 4x5, it works on all 4x5's, as long as you can get it on the right lensboard!

Tony, Yes your 135 Caltar will work with any 4x5 camera as long as you have a lens board that match the camera. For the Wista, a Linhof, Technika, Shen-Hao and many other lens boards will work.
For LF it is the Image Circle (IC) that is the most important parameter when moving lenses between formats but switching from a rail camera to a field camera makes no difference. 156mm or so IC is the most important factor.

Thanks for the help!! Another question, is buying a lens board I assume specific to the hole size or the lens brand? Could you also give me a few place to look to purchase one?

Thanks!

www.KEH.com has several previously owned Wista lens boards listed.

Look under "large format" in the "camera store" section for a lens board with a 34-35 mm opening (Copal 0).
