Several Soft Focus lenses compared

I did not use LF to compare.

^^^ Perhaps not but this thread is still useful, IMHO.

Well I had my rant.
Yes useful.
Ilike the fact that I can test without consumables.

For those that like using the iris in a shutter with the Imagon
Would you prefer the more rounded 10 bladed aperture of the Compur, the less rounded 7 bladed aperture with flatter sides of the Copal, or the even less round flatter almost indented [ S curve ] 7 bladed Sinar DB aperture?

For the 300mm or 360mm Imagons, I prefer the Compur to the Copal, not for the aperture shape, but because the Compur opens to a wider full aperture. The smaller Copal 3 chokes it down significantly. And personally, I don't think the aperture shape affects the image much, though some will argue that.

The rounder and more uniform the aperture the better, IMO, and this is true all all lenses in many (not most) situations.

Which Shutter is your Imagon mounted in?

Which Shutter is your Imagon mounted in?

My Imagon lenses? The 200mm is in an old Compound, 300mm in a Copal #3 with ten blades (I wish I had the Compound version), and the 120mm is in barrel and helical focus mount that I'm trying to remove the cells and mount in an old Compur #1 with many blades.

I only use my 360 in a Packard shutter that exceeds the aperture.

I did not realize that Copal Shutters had more than 7 blades. Yours must be an older version.
I just purchased a Compur #3 with a Symar 240 but the threads are the wrong size in the front to accept the front half of the Imagon.
