how do I know what kind of shutter I need for a Zeiss 210 f/4.5?

<p>I purchased an inexpensive Carl Zeiss Tessar 210mm F/4.5 lens, (SN 5397) intended for 13x18. Can anyone tell me how to determine what kind of shutter/lens board size I need? </p>

<p>Thanks!</p>

<p>To learn more about your lens, go here http://www.arnecroell.com/publications, scroll down and click on <strong><strong><a href="http://www.arnecroell.com/czj.pdf">Carl Zeiss Jena large format lenses 1945-1991</a></strong></strong></p>

<p>If you do this and read the pdf, you'll learn that your lens probably can't be put in shutter without machining. Given the costs of decent 210 mm lenses in shutter, your treasure is probably best used as a paperweight. </p>

<p>To make sure, unscrew the cells from the barrel and measure the barrel's length and the cells' threading (diameter, pitch). Go here http://www.skgrimes.com/products/new-copal-shutters/standardcopals to find standard Compur/Copal shutters' dimensions (tube lengths, threading) and here http://www.suaudeau.eu/memo/pratique/Les_obturateurs_centraux.html for more shutters' dimensions.</p>

<p>probably a compound IV or V shutter, but it wont screw in directly. you would need machine work. </p>

<p>For similar results, you're better off buying a Xenar lens in a shutter.</p>

<p>If I wasn't clear, shutters aren't inexpensive. There's a law of nature to the effect that every used shutter needs overhaul. More expense. Photographers' machinists don't work for free. Still more expense. </p>

<p>A modern 210 lens in shutter plus a shutter overhaul will cost less than shutter, overhaul and machining. </p>

<p>In general, lenses whose cells aren't direct fits in a modern shutter are poisoned gifts.</p>
