A former Olympus E-PM1 (and E-PL1) user, I've only had my Sony NEX-C3 kit (with 18-55mm) for a week today. Right after it arrived, I ordered a "Fotga" NEX to Nikon (G) adapter (works with new "G" lenses or classic AI/AI-S manual-focus lenses, cost like $10), it finally arrived today, so I mounted my old Nikkor 50mm f/1.8 manual-focus, it's one I got about 2½ years ago at a garage sale for $5 mounted on a broken Nikon FM2 35mm SLR body. It's ugly as my in-laws but works fine. According to the serial number it was made around 1980. Here are 2 shots I took of my son with it today. There is SERIOUS bokeh going on, especially with the 1st one which was shot at f/2 and only 4 feet away (the second one was also about 4 feet away but shot at f/2.8)--yet I managed to get the eyes in focus (and without using my Loupe), not a bad job if I do say so myself. Shot in RAW+Fine/Large JPEG, the RAWs were used & edited in Lightroom 3.5 and Photoshop CS2: I did have manual-focus assist on as well, also used focus peaking. Sometimes the peaking lines didn't outline the eyes, which were the priority (insufficient contrast?), zooming in to 15x helped with that. That said, the focus peaking definitely helped, and even regarding the magnified view set-up it worked FAR better than when I used this lens on my Olympus E-PM1, I could see details way better and toggling between "normal" and "magnified" view was far more fluid. I also have a Canon FD to NEX adapter on the way, as well as a Canon FD 50mm f/1.8 I paid about $25 for. I'm looking forward to seeing how that works. One week moving from the Olympus system to the NEX-C3, so far I'm enjoying it very much.
