Hi,

I'm looking for a front lens board for my recently won Sinar F2. A guy on ebay has one that says it's for "Copal 0." I look at lenses on keh.com and they say "Copal Bulb" (42 MOUNT). How am I to know if this is compatible?

Please accept my advanced thank you.

Darryl

the copal #0 shutter fits in a 35~36mm hole (approx 1-3/8 inch). The copal #1 shutter fits in a 42mm hole (approx 1-5/8 inch). The Syncho-Compur shutters normally fit in the same size hole as Copal#1.

Make sense?

Yes. Where did you find this information?

Just comes from experience. I bought stuff and measured. I guess you can also kinda infer some of it by looking at lens mfgr's data sheets....see for example, http://www.schneideroptics.com. Look under info->vintage lens data-> large format lenses....one of the specs is usually the size of the hole that shutter fits in.

Thank you both. So, I figure that I need a Copal 1 for these lenses, 98% of the 210mm lenses say "Mount 42."

yes. practically all 210mm lenses (intended for 4x5) sit in a Copal #1 shutter...or the equivalent.

Many older 210mm lenses are in Compound #3 shutters, e.g. Xenar 210/4.5 and Angulon 210/6.8. Newer lenses tend to have smaller max apertures, and come in #1 shutters (e.g. 210/6.1 Xenar).

Brad, the Synchro Compur shutters were made in many sizes I have a 00 and a 0, the Synchro just indicates the flash sync.

SkGrimes also has good information regarding hole size on their site.

KEH sells a lot of used stuff. The holes can be for anything. From some older shutters to the latest. So they tell you the size of the hole. You'll really appreciate this when looking for a board to mount those less common shutters.

New boards are bored for one of the common modern sizes or blank [no hole].

Yes. I fully realize this. Thus, the mild qualifier, "normally", in my statement. Still, you are right, I probably should not have added that laast sentence at all as it is based entirely upon my subjective experience and could be quite mis-leading. Thanks for clarifying.
