Panasonic Lumix DMC-GH1 DSLR Review at camcorderinfo.com – Jeremy Stamas:
Judging it solely on its video capability, the Panasonic GH1 ($1499.95 MSRP) is a strong camera. It is the first video-capable DSLR that truly offers the gamut of manual controls that we expect to see from such a device. This isn't all that surprising coming from Panasonic, which usually offers an extensive amount of manual controls on its consumer camcorders.
We were pleasantly surprised with the GH1's autofocus system as well. You don't have to push the shutter button halfway to engage it, and the camera doesn't make any loud noises when it attempts to focus—both of which were problems on the Canon T1i and Nikon D5000. The GH1's autofocus wasn't quite as good as a regular camcorder's, but it was pretty darn close.
