eric_mortensen3 Posted November 20, 2002 Share Posted November 20, 2002 I recently purchase a Fujinon 210-WS with a seiko 1 shutter. This is an older version of the lens with a 58mm filter size, and writing on the inside rather than outside of the front barrel. The shutter seems larger than a copal 1 but smaller than copal 3. My question is does anyone know what size hole to drill for this shutter size? One other question about seiko shutters. I cannot open the shutter to focus the lens without cocking the shutter. Is this normal? Further, when I use the lever to open the shutter while it is cocked, the shutter does not seem to open all of the way even at maximum aperature. You can still see the very edges of the shutter when looking through the lens, whereas if you open the lens with the bulb setting you cannot see the edges. Is this shutter out of adjustment, or is this just the way it was designed? Thanks in advance for the help. Eric Link to comment Share on other sites More sharing options...
tim_atherton2 Posted November 20, 2002 Share Posted November 20, 2002 Eric - so you finally found one... where did you get it? Link to comment Share on other sites More sharing options...
eric_mortensen3 Posted November 20, 2002 Author Share Posted November 20, 2002 Tim, I got it from a seller on ebay that lives in Tokyo. I haven't been able to verify that it covers 8x10 since I don't have it mounted yet, but Im keeping my fingers crossed... Link to comment Share on other sites More sharing options...
jim_galli4 Posted November 20, 2002 Share Posted November 20, 2002 Eric, The preview on my Seikosha 0's works the same as what you're finding and it's about 1/2 and 1/2 on the blades retracting all the way in. Some do and some don't so sounds like nature of the beast. Things weren't as standardized in the '70's as now. I've found Congo 180's in Seikosha 0 that weren't 0! They were american thread. ie. you could have used those Seiko shutters with a Graphlex 135 Optar elements! So you could have anything although finding US threads instead of metric still seems wierd.

s.k. grimes inc Posted November 21, 2002 Share Posted November 21, 2002 Seiko made some oddball size shutters that you almost never see. This reads like one of those. (#2 size) I don't know the dimension for the hole size and suggest you will have a good deal of difficulty trying to research it. Best thing is to just measure the shoulder of the retainer to get the diameter. Alternately send it along and I'll bore the hole and mount the lens.
