| primus96 Joined: 13 Nov 2003 Posts: 225 | Posted: Sat Jun 26, 2004 11:53 am I believe the W.A. Dagor covers 70deg as opposed to 60deg for the usual Series 3 and is slower(f8) as opposed to f6.8 for the normal Dagor. If I am right your lens has a image circle of approx 120mm. This means it won't cover 4x5 but will do fine with the rollfilm adapter and accomodate any movements you desire. | ||

It says that Perigons cover around 90 degrees. So both of these beasts will do for 4x5. The real question is whether the price is low enough that they can be disposed of, if not, after all, wanted at minimal loss. OTOH, if these things are on eBay, the Perigon will bring a fair amount. Cheers, Dan | ||
| Nick Joined: 16 Oct 2002 Posts: 494 | Posted: Sat Jun 26, 2004 7:52 pm I remembered 80 degrees for the WA dagor. Doing a little looking it seems F/22 80 degrees F/45 100 degrees. Only 70 degrees at F/8. To me that means you'll have trouble focussing at F/8. Even F/22 won't cover the corners with any movement. But if a person would like focussing at F/45 it's fine. Reminds me why I passed on one last year. | ||

Which one do you think I must pick first?? Which one is better??? Will they work for my 4x5"?? Sorry to bother, but you are the best resource I have. | ||

Bear in mind that thanks to the postal system and eBay Colombia is not cut off from the rest of the world. If you get a lens and don't like it AND it is in good order, you should be able to recover much, if not all and then some, of your investment, by selling it on eBay. About resources. I like http://www.graflex.org, but there are other places to look for information on and advice about large-format equipment. Try http://www.largeformatphotography.info/lfforum/ and the large format forum on http://www.photo.net too. Its been a while since I did a google search on rodenstock and perigon. Have you tried that? Cheers, Dan | ||

It's rather small in my opinion, but I'll just give it a try. The Dagor goes to a Friend of mine who has a Toyo 45 CF. I hope It work for him as well as mine. I'll run test on both of them and I'll let you know about the results. | ||
| musashi Joined: 16 Feb 2004 Posts: 17 | Posted: Wed Sep 01, 2004 1:26 pm At Last I have the Perigon!!! I tested it, but... When I'm focusing with it at infinity, The short focal distance leaves the lensboard, inside the Camera body. This fact does not allowed me to do any "movements" I never had a 90mm before, so... My concern is: All the 90mm will have the same problem??? My Camera is a Pacemaker Speed Graphic (4x5") Sorry for the stupid question, but I'm learning every day with these cameras!!! Thanks a lot!!! | ||

Measure how far it is from the ground glass to the lensboard. Some lenses have longer flange distances [The distance from the film plane to the flange]. I'm thinking about the Nikon 90mm F/8 which needs about 100mm to focus at infinty. Some older lenses might be closer to 90mm. The obvious answer to your question is a recessed lensboard. But they can be a pain to use. | ||
| musashi Joined: 16 Feb 2004 Posts: 17 | Posted: Wed Sep 01, 2004 2:42 pm Thanks Nick!! I'll search for the Nikon 90mm then. I'm not really into the recessed lensboard for now. | ||

that's good, because recessed lensboards don't work on Speed Graphics, the back of the front standard has a hole that makes it impractical. Les | ||

I haven't tried it, but I think a shallow cylindrical cup about 2-7/8 ins. in diameter and perhaps an inch or an inch and a half deep, formed of thin sheet metal, could be mounted behind a "Pacemaker" lensboard to carry one of the old, diminutive wide angle lenses (a 75mm. f:9 "W.A. Dagor," for example) in a small shutter. I think it would leave you room to reach in and set the shutter, and to attach an offset cable release extension. | ||
