It's the latest, greatest 40mm from Zeiss. Highly corrected with an auto floating element for closer work. Does have some linearal distortion, which was the compromise to get tack sharpness across the field-of-view. I compared it to my 40 CFE with manual floating element, and the corners were much, much, much better with the 40IF.Marc, what is the Zeiss 40/4IF ? Is it the Distagon T* 4/40 IF CFE for Hasselblad?
I assume I'd need an adapter then?!
Dou you know how the distortion is? Has it linear or moustache distortion?
Thanks again!

Front out-of-focus areas can often be quite ugly compared out-of-focus areas behind the plane of critical subject focus ... which is what we usually look at and compare. Both Irakly and I noted how smooth and delicate the front out-of-focus areas were with the Contax 55mm. I've not seen many wider lenses that are really good at this. Some Leica optics are, but it's not that common in my experience. Just an observation.
