**Tim Layton** · 21-Dec-2011, 08:52

I am looking for a retaining ring for an Rodenstock 300mm f5.8 Imagon. Anyone have one to sell or know where I can get one?

Thanks,

Tim

Hey Tim, if your 300mm Imagon is in shutter. Then you will be looking for a flange for the #5 compound shutter. Pretty sure someone had one for sell on this site or eBay. I just saw this recently so look around.

If it's in barrel then I'm not sure of the size of flange needed. Sorry I don't have either to sell to you.

Yes, it is in a #5 compound shutter. I will need to look for a flange and not a retaining ring.

Thanks,

You'll be able to identify the proper flange for the Compound shutters as most are aluminum w/ black enamel and most times stamped w/ the country of origin. Germany.

Here is the metric measurement you'll need. 89.75-M1.0

SKGrims has them for $65.00 plus shipping and they are more than likely in stock.

Here's a link-http://www.skgrimes.com/products/mounting-flanges/metric-stock-flanges

I'm sure there are other flanges for the #5 Compound that may be made out of brass but most I have seen follow the above info
