355mm G-Claron shutter fit?

[Pete Skerys]

Hi,
I've come across a 355 g-claron in barrel and was wondering if it would fit a copal 3... do *all* 355s fit copal 3s?

fits a copal #3 without any modifications screws right in

Actually, some older 355 Gs fit in Compur 3 shutters - not the Copal 3. I do not know where the line between "new" and "old" is to differentiate, though. Also, if yours is a "new" one, be sure you get a Copal 3 and not the smaller Copal 3S as that will definitely not fit.

Some older 355mm G Clarons fit Compound #3 shutters. I think they have silver front barrels.

Mine fits a Compound, and has silver front barrel. That doesn't necessarily mean that all silver-barrel 355's will fit Compound #3, nor that all black 355's will fit Copal 3. I don't know when they changed what...

[Kerry L. Thalmann]

Didn't the older 355mm G Clarons also have a smaller front filter thread (67mm instead of 77mm)? I'm not sure if the correlation is 100%, but that may be one way to tell which shutter a particular 355mm G Claron fits into. I can't imagine Schneider re-doing the mechanical design of this lens twice (once for a different shutter and once for a different filter size) twice within a couple year period.

Ole, what size filters does yours take?

[Ernest Purdum]

Kerry is right (of course) about the filter sizes. For what it's worth, the older ones are all-cemented (Dagor) design, while the newer ones are air-spaced (plasmat) consruction.

[Ole Tjugen]

I'm a bit too far from my lens to check the filter size right now, but from memory 67mm seems more correct than 77mm.

However it's not old enough to be a Dagor, it's definitely a Plasmat.

Nothing whatsoever surprises me when it comes to mechanical redesign of lenses.

[Capocheny]

Mine fits into a Copal 3 shutter... and I think it has a 77 mm front filter ring.

I'll check a bit later on and report back.

Wouldn't it be great if they could all come to some standardization? :>8

True, but standards change with the times and the market. While the used lens market can be confusing now, it's probably appropriate for Schneider to have switched to the Copal 3 with the later versions of the lens.
