Dagor front threads

[Steven Nestler]

Hi.
I just acquired a 12" Dagor in a shutter. I love the lens, but cannot thread a filter to it; it seems to be almost; but not quite; 58mm. Any suggestions?
Thanks,
Steven

In their day, Dagors were intended to use slip-on adapters for series filters or gels. Measure the outside diameter of the element, and visit used camera shows in your neighborhood to find one. Good luck.

S. K. Grimes can make a filter adapter for the Dagor. Mine screws into the lens threads and takes a 67 mm filter. Works great.

You can also use Tim @ LensN2Shutter.com which is on the West Coast. He is installing a 45cm Dagor red dot inmy copal 3 and will be shortly installing my 240mm & 360mm in front mounts in an alphax shutter. He is very knowledgeable, keeps you updated, and does great work. I am also going to get him to make an adapter so I can use my 67mm filters w/ my 45cm dagor red dot. I definitely recommennd him. JW

What's a Dagor red dot?

I think Jon must have an artar there, not a dagor.

FYI, the one I had S.K. grimes make for my 12" Dagor also fits the 19" Artar.

You are right Robert, I was thinking "Goerz" when it read "Dagor." However, my recommendation does stand...Tim at "lensn2shutter.com" does excellent work.
