janvanhove Posted July 26, 2004 Share Posted July 26, 2004 Hi, Just wanted to make sure...I just got my hands on a 300/9 Rodenstock Apo-gerogon graphic arts lens, in barrel, and i heard somewhere that this lens can screw in directly in a copal 3 shutter... Am I right or just completely out of my mind ? Cheers Link to comment Share on other sites More sharing options...
donald_brewster Posted July 26, 2004 Share Posted July 26, 2004 Probably best to check with SK Grimes (http://www.skgrimes.com). Their list has the 360mm f/11 APO Geragon being fitted into a Copal #1, so I'm guessing that the 300 wouldn't need or fit a Copal #3. Link to comment Share on other sites More sharing options...
jim_galli4 Posted July 26, 2004 Share Posted July 26, 2004 The Gerogon's are excellent but unfortunately they don't take to any shutter easily. Get youself some Efke 25 film and use the lens cap. Or investigate Packard shutters. I find them very easy to use for LF where "normal" exposure times hover in the 1/4 to 1/2 second range. That 300 should cover 11X14 with room to spare.

dan_fromm1 Posted July 26, 2004 Share Posted July 26, 2004 Second Brewster's motion, check with skgrimes. And I agree with Jim too. I once had a 210/9 ApoGerogon. One cell, the front if I recall correctly, was threaded 40x0.75, went right into a #1. The rear cell was too large to go into the rear of a #1. Or perhaps it was the other way 'round. Point is, one cell would go into the shutter, the other wouldn't. Not fun. If you need short timed exposures, front mounting on a big Ilex is an option. When in doubt, ISO 100 or slower film. Cheers, Dan Link to comment Share on other sites More sharing options...
joerg_krusche Posted July 27, 2004 Share Posted July 27, 2004 Hi, just in case you have the CL-version of the Apo-Gerogon 9/300, then front and rear cells may be screwed direct into a Copal 3 shutter. The rear cell has two threads, the smaller one will do. Overall length of the lens may be a tad longer than in repro application barrel , but with a symmetrical lens this need not be undesirable for infinity applications, at least it works more than reasonably.

janvanhove Posted July 27, 2004 Author Share Posted July 27, 2004 thanks for the answers ! I mailed SKgrimes, and basically the answer was : we are not familiar with that particular lens... From your answers, i gather that the best way to go will be a packard shutter, and i'll first try the "drop shutter" option (basically a board with a hole that is dropped in front of the lens, not very precise, but moreso than lenscap shutter... I'll keep you posted on my solution... PJ Link to comment Share on other sites More sharing options...
