Get Panasonic S1R at B&H Photo.
This page puts the Leica 90mm f/2 APO-Summicron-SL ASPH to use for portraits on the Panasonic S1R using Eye AF focusing mode. A reflector was used for fill lighting. The 90/2 performs beautifully, but Eye AF was a sad story.
Images at up to full camera resolution. Some images are pairs of apertures for comparison.
As in previous portrait attempts, I had trouble with the Panasonic S1R Eye AF. Too often the S1R Eye AF focuses on eyelashes or nose in front of the iris. Many shots were discarded from this page with about 12 usable shots out of 40, 2 or 3 ruined by motion blur and the rest ruined by the failing of Eye AF. I was thus left with only a small fraction of the best poses.
