I made a post on the mu-43.com forums about birding and m4/3 cameras. But I'm wondering what other options exist in serious compacts for birding, particularly in the realm of the APS-C sensor? Ricoh does not have anything, Sony is not there yet, what about Samsung? Any leads I should follow for other brands/cameras/lenses? Or is the m4/3 option the best option right now? Right now "birding" is just a casual interest; were I to get serious about it I might reconsider the DSLR options. I have an Olympus E5 that I could use with Olympus teles. Thanks!
