It's been exactly 4 weeks since I ordered the c-mount to micro-4/3 adapter for my G1, and it sure took its time to arrive. Absolutely the most eagerly waited adapter ever, since I have some of the fastest glasses I own in c-mount to try out. The adapter was purchased from JinFinance on eBay. Very well made and works wonderfully. The only problem with c-mount lenses is that the lens to sensor register is actually shorter than the G1, so the lens has to be mounted in a way that goes further into the sensor than the mount otherwise allows. This limitation make larger c-mount lenses unable to focus to infinity. My JML 50mm f0.95 is one such lens. Too bad, but at least it can focus to about 1.5 meters away. All other smaller ones focus to infinity without problems.
Below are few pictures from some of the c-mount lenses I tried. Very intriguing. Very different than the normal SLR lenses I have used.
Dallmeyer Speed 25mm f1.5 -- Gorgeously made lens and produces very interesting images with swirlling background:

JML 50mm f0.95 TV Lens -- I acquired this lens by pure luck. It came with a sister lens, the 25mm f0.95, but unfortunately vignettes heavily. In fact, it has dark corners.

Kern Paillard Switar 75mm f1.9 -- One of the most popular c-mount lenses for the G1. It's a beautiful lens. Too bad it's not the Macro version.

Notice that it also has the swirlling background, just not as severe as the Dallmeyer. Panasonic G1 with Switar 75mm f1.9
