Not bad!
Just a small disturbing spot light from her left ear ring...

I also use the 140/1.8 lens(es). Both the 4 glass and 6 glass version.
What version did you use for this beautiful portrait?

Very nice! This is the first I've heard of this optic. So, what do you guys use as a focusing helical for it? Or maybe just some sort of sleeve?

ehemm Michael, where have you been so long to have missed that...?? Wink
Honestly, we are talking about projection lenses since quite a while and me and others have shown how to mount them:

Disturbing spot light (?), it's a highlight and it's cute!
Certainly it is the double gauss version, very easily seen
by the rendering this lens has.

Thanks for the link. Sorry, I guess I've tuned out projection lens discussions. Mostly because of my own poor results using them. You know, the plastic pieces of junk that were used with the Kodak and Bell & Howell projectors over here in the States.

By the way, the amazon link you have in your blog returns 0 hits. Rafcamera is still good, though. So, this is where you get the actual adapters from, eh? Wow, they have so many . . .

My expertise in how different lens systems render a photo is very small. Working on it!
Double Gauss system, ok, 6 lens elements then Smile
Had to look that up...

I think the 4 element version is a Petzval type and there is no typical Petzval swirl in the superb portrait above, I guess that would also mean that the 6 element version would have been the obvious one Smile
