dan kowalsky Posted January 22, 2001 Share Posted January 22, 2001 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 Link to comment Share on other sites More sharing options...
pete_andrews Posted January 22, 2001 Share Posted January 22, 2001 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.

jim_galli1 Posted January 22, 2001 Share Posted January 22, 2001 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. <p> Jim Galli Link to comment Share on other sites More sharing options...
andres_suurkuusk Posted January 23, 2001 Share Posted January 23, 2001 I use Rodenstock Apo-Rodagon-N 80/4 for macro <a href="http://www.hot.ee/andress/24.htm">work</a>. Link to comment Share on other sites More sharing options...
pete_andrews Posted January 23, 2001 Share Posted January 23, 2001 Beut Andre!<br>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. Link to comment Share on other sites More sharing options...
alpshiker Posted January 23, 2001 Share Posted January 23, 2001 Jim, your experiment sounds interesting. Were your shots at close-up range or at infinity? Link to comment Share on other sites More sharing options...
jim_galli1 Posted January 23, 2001 Share Posted January 23, 2001 They were landscape and architecture shots at or near infinity. Jim Link to comment Share on other sites More sharing options...
