Panasonic Lumix GH1 Digital Camera Review at DigitalCameraInfo.com – Steve Morgenstern:
If you've been tantalized by the idea of an interchangeable-lens camera that shoots high-def video, though, Panasonic delivers the goods. While video quality results aren't radically better than the video-enabled SLRs we've tested, they are superior overall. More important, though, are two key factors. Unlike the SLRs, the Lumix GH1 offers an extraordinary level of control over your video shooting settings, including aperture, shutter speed and even ISO settings, plus fine adjustment of white balance, color and more.
A gallery of full-resolution sample images is also provided.
Panasonic Lumix GH1 review and samples at What Digital Camera – Score: 85%, and Mat Gallagher issues the following verdict:
The GH1 is an exceptional camera, but more than anything it is an exceptional video camera. In terms of still imaging it has some improvements on the previous G1 model, though these are not significant enough on their own to justify the huge price difference.
There's also a gallery of full-resolution sample images with a nice variety of shots for you to assess the image quality of the Lumix GH1 with.
Nice pixel-peeping contest setup at dkamera.de – Olympus Pen E-P1 plus Olympus M.Zuiko Digital 14-42mm lens compared with the Panasonic Lumix DMC-GH1 plus Lumix G Vario 14-140mm Mega OIS lens at all ISO levels.
