The Canon 40mm is also interesting. Yes, it does fall apart somewhat (to put it mildly) towards the edges, but what on earth are Canon doing building a 40mm lens for $200 with an image circle like that!

Here is a sample from today with the 40mm Canon (I paid 168 Euros, sales tax included). Pretty impressive on a (small) MF-back (Aptus II8) except for the far, far corners. After a 2:3 crop, the complete image is tack sharp!

Heres a bunch of "real world" photos taken with the Zeiss 85mm f1.2 and Leaf 22/33 MP backs (fullframe no crop): http://www.flickr.com/photos/[email protected]/sets/72157627800477689/
Theres a few on my website too in probably better quality but mixed with others, most of them are near the end: http://www.markorepse.com/

hi mark, these are really nice. what camera did you shoot these with? i have been planning to modify a contax 645 body to fit a fd 85mm f1.2 like a guy who has done this with his mamiya 645 (can't find the link at the moment).
i planned on getting the mirror cut down to make the extra clearance. i did an experiment and you can cover half the mirror almost and still get a reasonable viewfinder image. i figure focusing being the biggest issue with this. i struggle to focus my hassy 110 f2

if i could figure out how to put a electronic mount to run my ef 85 f1.2 and my 50 f 1.0 so you can turn the focus ring i would (these need power to actually turn the ring). not sure how to do this.

Hi Paul,
These were shot with a modified Mamiya 645. I wrote a few words on this here: http://www.getdpi.com/forum/medium-format-systems-digital-backs/35317-85mm-f1-2-medium-format.html
Focusing is indeed very tricky, at longer distances and in poor lights its nearly guess and check, much easier closer up though. The magnifier helps.
