I've an old TTA aerial lens (WWII vintage) that I'd like to mount on my 2D.
But finding a ring/nut has been nigh impossible.
So the options are ...
(1) If you have a ring that you know fits, I'm interested ... or
(2) Anyone got one of those aperture mounts available @ a modest price?
As far as shutter, I'll probably construct a Jim Galli type.
They're cheap and quite reliable. :-)
