A few of my photographer friends have been extolling the virtues of the new mirrorless micro 4/3 cameras. I try to wait until new toys are more affordable, but after seeing a couple of these tiny little miracles (they're smaller than my old film cameras!), I carefully scoured sources for an affordable micro kit. After patient searching, I managed to acquire a barely used Olympus OM-D EM-5 mirrorless. It came with a 14-42 kit lens, then I acquired, again on the cheap, a 42-150 zoom lens to go with. Armed with this lightweight wunderkind, I went to visit the Morikami museum and Japanese gardens with a friend. For a little camera, this mirrorless does big work! I shot in RAW and did minimal editing. While the camera CAN manual focus, unlike my DSLR, it doesn't let me know where the focus is if I rotate manually, so I shot using autofocus. It was fairly easy to shift the focus as well - on the attached shot of the dragonfly, at first, the camera wanted to focus on the background plant, but I was able to refocus to make the dragonfly tack sharp.
While I don't plan on giving up my DSLR, the Olympus is probably going to be my carry-around camera.
