Oops, an extra "in" in the title. Oh well.
I have a question for all of you Seiko shutter experts. I recently purchased a 135mm Fujinon W (the single coated version) to use as a wide angle lens with my 5x7 back. It is in a really nice Seiko shutter. (I had one of these years ago. It came in a kit that I purchased to get a roll film back. I sold most of the kit including the back and the 135. Shortly thereafter I got the 5x7 back and wished I had kept the 135mm Fuji! Amazingly, this lens appears to illuminate 6 1/2 x 8 1/2!! I will have to expose some film to test that out.)
Anyway, back to the point of this post.
Over the years I learned that we should store our Copal shutters with the preview lever set to open. Is this also true for Seiko shutters? Unlike a Copal shutter, the preview function for a Seiko requires cocking the shutter first. Seems like that would not be the preferred approach for a Seiko, but I am no expert.
I tried to search the forum for an answer. If the answer is here, I can't find it.
While searching, I read that we should store lenses with the shutter set at "T." Is this true? What does this do? For that matter, what does storing a Copal shutter with the preview lever on open accomplish?
Thanks in advance everyone!
