I've been testing a pre-production version of this interesting lens and have posted some images on Flickr, including shots at f1.6, various 100% crops and a few full size files. The link is here: SLR Magic/Noktor HyperPrime 12mm f1.6 samples - a set on Flickr

I've also put up a video, nothing flash at all but showing the flexibility of a wide lens that can go very close to the subject, as well as a short run showing no sound from the stepless aperture ring: SLR Magic Noktor.mov - YouTube

All the best,

Don
