In response to BJL, I think you should get this camera in hand, with the lens(es) you intend to use, before buying it. I tried it in the store, with the 12-50 kit lens attached. My reaction was that that lens was designed to balance rather nicely with the camera, felt svelte, in fact. The impression may have been helped by the fact that the lens was in silver finish. Pancake-style lenses would work nicely. I knew that my m4/3 14-140 wouldn't feel nearly as good. As for my collection of 4/3rds lenses I bought for my old E-1 and E-3? I think you'd feel you had a tugboat pulling a canoe, and the camera is the canoe. Am I exaggerating? Well, I didn't put a 4/3 lens on the camera, and of course you'd have to add the (small) bulk of the adapter, too; I think much depends on how you want this combination to feel for hand-held shooting. Also, the "grip," such as it is, is puny. With a large lens on this camera, you will never hold the camera/lens combination by the camera, always and only by your hand around the lens. You asked about image quality. I think the m4/3 cameras with their lenses have given me files every bit as good as I got from the larger/heavier lenses on my 4/3rds cameras. And the sensor, while maintaining the same size as the older sensor (in fact, at least some of the new ones are larger to accomodate variable aspect ratios) enjoys the benefits of advances in engineering. --Barbara
