Enlarging lens used for camera lens

Hello to all,

 

<p>

 

I have a Rodenstock Rodagon 360mm 1:6.8 /45. It is an enlarging lens that I stopped using for enlarging because of it's "too long a focal length"for my needs. My question is, can I mount this on a lens board for my 8x10 Master View and use it as a normal lens in barrel? What quality effects + or - would I expect at different shooting positions ? I do not have a focal length lens in this area and it would fill the gap. If any of you have tried this I would appreciate your help.

Thank you for your time,

Dan

Hi Dan, I started an answer earlier and got side tracked........this

working for a living, what a bother. Anyways I experimented with a

situation this weekend that has some parallels. I was curious about a

135 Componon S that was idling in the drawer so I mounted it in a

Polaroid size O from an oscilloscope camera, put it on my Z VI and

made 5 negs. I think the rule with all of these is first of all you

have to stop down to f22 because the lens geometry that optimizes for

1:1 introduces other aberations that don't disappear much before f22.

The result was that it has a decent image circle, about 189mm, and the

negs were actually incredibly sharp. In fact the lens will go into my

"kit" as a keeper. It replaces an Ektar 127 f4.7. Total investment,

about $48.00. Something else you can experiment with is if you have

other focal lengths that are in Copal 3, you may be able to screw the

360 6.8 elements directly in. 2 lens element sets, 1 shutter.
