I'll be looking forward to posting some pics from my GF1/EOS combo - the adapter arrived today. It fits both EF and EF-S lenses, so I'll be trying it out with:
EF-S 60mm Macro (alot cheaper than the 45mm Panasonic Macro if it works!)
EF-S 10-22mm (pretty wide, and with the smaller sensor I get quite a bit of depth of field even wide open - 3.3ft to infinity)
EF 85mm 1.8 (I'm very interested to see how this performs)
Lensbaby 2.0 (especially given the upcoming contest! Seems cool, but needs to be on a tripod to hold steady)
I'm curious to see how the sharpness and corners look, since I have to either shoot these wide open or do the 'hold down the depth of field preview button' trick when I take it off my Canon body.
