wieslaw1 Posted March 14, 2006 Share Posted March 14, 2006 My 4x5 Beseler does not allow to make 20x24 enlargements with a 135 mm lens.. The extension is not sufficient and I hate to cut a hole in the base-board. Likewise, projecting an image on the wall is impractical. In this case I decided to use a 120mm taking lens by Schneider as an enlarging lens. I just purched one, but did not received it yet to experiment. Any comments?

mike_earussi1 Posted March 15, 2006 Share Posted March 15, 2006 What A friend of mine did was to have an extension made that fit between the enlarger and it's baseboard, I think it was between 6"-8." This gave him enough extra room to make 20"x24" prints. Link to comment Share on other sites More sharing options...
mona_chrome Posted March 15, 2006 Share Posted March 15, 2006 Kind of interesting, as I can make 20x24's with a 150mm. Anyway, I doubt the 120mm will work very well. Friends of mine have had problems with vignetting with the 135, so the increased angle of view might present a problem in that regard(light doesn't cover at increased angle). I assume you are talking about the use of the 135mm and a 4x5 negative? Link to comment Share on other sites More sharing options...
loreneidahl Posted March 15, 2006 Share Posted March 15, 2006 I got an older Omega D2 (4x5) enlarger that I took off the base board and mounted on a raised platform behind my work surface in my darkroom. Height of platform is about 8" and its adjustable. No problems making 20x24 this way. Link to comment Share on other sites More sharing options...
randall ellis Posted March 15, 2006 Share Posted March 15, 2006 Have you considered taking the wood baseboard out of the metal frame rather than cutting it? If I remember correctly, you can remove the wood portion of the baseboard from it's metal frame, move the enlarger to the edge of the table, and then project onto the floor. Stability might be an issue so use your best judgement... - Randy Link to comment Share on other sites More sharing options...
wieslaw1 Posted March 15, 2006 Author Share Posted March 15, 2006 Thanks for your input. For some reason I have not thought about extending the steel frame. It is possible, but would require making of 4 pieces of metal profile. Quite time consuming with an access to a well equiped metal shop. (Which I have). Projecting beyond the base, on the floor � this I could do with a smaller Krokus enlargement, but here the shaft could be rotated on the base. All you needed was to put a counterweight. Lets see what the 120mm will do. I do not see a reason for vignetting. This lens covers more than 4x5 area. All I need is to reverse it. Link to comment Share on other sites More sharing options...
tonight Posted March 15, 2006 Share Posted March 15, 2006 I have a Rodenstock Rodagon-WA 120mm f/5.6 enlarging lens designed for just this purpose. I am able to get a 22" x 27" image on my Beseler 45MXC baseboard with 4x5, and get no corner light falloff at any aperture. Link to comment Share on other sites More sharing options...
wieslaw1 Posted May 12, 2006 Author Share Posted May 12, 2006 The Schneider 120mm/5.6 taking lens works like a charm as an enlarger lens on my Beseler. I can make enlargements bigger than 20x24 sharp and brilliant. Link to comment Share on other sites More sharing options...
