Ok, got my copy with a cheap adapter. Even though the mechanism / distance scale on the barrel indicates that it is a parfocal lens, I have actually found that I can focus to infinity at 70mm, but not at 35.
Anyway, it was a little bit dark when I went out to take "proper" photos, so all I can share now is a test shot.
Stopped down to F8.0
No sharpening applied, no CA correction.
Center at 100%
Corners at 100%
Note this is on a 40D, handheld, shutter at 1/400. I think I may get slightly better results if I could go further to infinity (this was at the very stop) so I think I'll get a better (thinner) adapter.
