New here from the Serious Compacts forum. I have a few questions in regards to birding and m4/3 lenses and cameras. I recently pulled out my old binoculars and began to observe the wildlife around our home and local parks. I was really enjoying it and eventually purchased a higher quality pair of optics. But it is odd for me as a photographer to look through optics and not be able to take a picture. Eventually, I'd like to have a camera/lens pair that would allow me to capture birds. Right now I am not set up to do that as all of my current lenses across various cameras are around 28-72mm. I don't currently own a m4/3 camera, but in the past I owned the Olympus E-P2. My questions involve using m4/3 cameras and lenses as birding cameras. I know that I need length (up to 600mm), but the lower weight of a m4/3 setup is appealing for my purposes. I am not a "birder" yet; it's just a casual interest. I also have an Olympus E5 camera, but the lenses appropriate for birding, though outstanding, are heavy and expensive. If I get serious down the road then I can re-evaluate. So, for birding are the m4/3 cameras perfectly viable options? Which of the longest m4/3 teles seems to work best, the Olympus or Panasonic? Which cameras? With its built-in EVF the G3 looks appealing, but I do like the Olympus rendering and color. BTW during this summer's vacation I'll be in Cape Cod and Florida, both good birding locations. A m4/3 camera could be my optimum travel setup. In the past the dynamic range and low light capabilities discouraged me, but I do have a large number of great pictures from the E-P2 and the Panasonic 20mm lens. Thanks!
