Hello to all,

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

Enlarging lenses are great for macro work on the camera, but I've never tried one at infinity. Why not just lash up a make-do panel out of cardboard and give it a quick test? The GG image should be enough to tell you if it's a complete no-hoper.

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.

I use Rodenstock Apo-Rodagon-N 80/4 for macro work.

Beut Andre!
I would never even have considered that colour combination, but it works extremely well. Is the background colour from a reflection, or from coloured Perspex? I've never seen plastic in that shade of blue.

Jim, your experiment sounds interesting. Were your shots at close-up range or at infinity?

-- Paul Schilliger (pschilliger@smile.ch), January 23, 2001.

They were landscape and architecture shots at or near infinity. Jim

Hello all,

Check out http://www.wisner.com/myth.htm regarding the use of flat-field lenses (i.e enlarging lenses) as normal lenses.
