Seiko/Copal shutters

[friedemann_pistorius]

Hi all,

 

<p>would a lens currently mounted in a (dead) Seiko B shutter also fit into a Copal 0 shutter (both 35mm mount)

by simply unscrewing it from the Seiko and screwing into the Copal?

<br>I'm aware of the fact, that the lens elements (assuming they really fit into the Copal shutter) would

probably need some fine tuning, but that's another question. I simply would like to know if the physical

dimensions of both shutter threads are the same, before looking for a shutter.

 

<p>A short answer would be of great help. <p>Thank's!

short answer, yes. Long answer, it's more cost effective to have the Seiko rebuilt, it's a fine shutter and will likely outlast you.

All I can add is that my 75mm SA will screw into the Seiko shutter from an old Mamiya C3 camera, BUT a lip on the rear thread prevents proper seating. I've also had this Seiko apart because the cocking lever is broken, and I have to disagree about the build quality - mediocre to rough IMHO. It's much the same story with the Seiko shutters built into Kowa 6 lenses.

 

Having said that, it depends on the fault whether it might be more economical to repair the shutter. It's probably worth getting an estimate.
