Damned progress! I used to have a Softar 2 for the 'blad and I bought a conversion ring for use with it on the Nikon. Then, when I sold the 'blad stuff (one of my major mistakes in life) the Softar, I realised, had gone with it.
I've a shot here fom the website that I think I can find within the next few minutes, of a girl sitting in a park in Singapore for a Tennent's Calendar. It was with the Softar (on Nikon), but the problem with it, scanned to use with the Internet and slightly sharpened, is that the halo look vanishes a little... about the only place it shows is on her right leg (left in pic) at the part where the dress is. For anyone not familiar with the effect - you see it as a white(ish) parallel shape on backlit stuff, mostly alongside the highlights. Oh, I've also got another one, from the 'blad with a 150mm Sonnar, of Nina Carter, probably London's top glam girl of the era and, later, an ex-Mrs Rick Wakeman. For this job, she played a demure jewellery calendar model.
Ah, those wonderful creatures of living legend!
