Before I go full bore with the 4/3's format and buy into the lens collection, my understanding is that I can get an adapter for my soon to arrive Oly E-P3. Only one lens is a DX lens, but a few of the remainder (FX) are good and and the rest are excellent gold ring Nikkor lenses. I would dearly love to be able to use those in the interim. This poses another question. Since I'm new to this community and the micro 4/3 (even though I haven't even held my camera yet), are there certain websites that cater towards the m43 genre? Basically, Adorama and B&H and a select other few have been my constants for on-line purchases of dSLR gear. Where are some reliable on-line retailers for this group? Thanks in advance.
