Panasonic announced the new Lumix DMC-GH2 yesterday, and we got a chance to try out a working product at their booth. Our first impression was, “wow, this thing is really fast to focus!” Panasonic claims AF speeds as fast as 0.1 second with the 14-140mm lens set to its widest setting - and indeed, we found that focus acquisition was basically instantaneous at that focal length, even in the relatively dim lighting of the stand. What was possibly even more impressive though was that it focussed almost as quickly with the lens zoomed all the way in to 140mm - it was almost scary to see a completely blurred subject standing at the other end of the room snap into focus in a fraction of a second. Of course further testing needs to be done to see if this blazing speed doesn’t compromise accuracy, but our first impressions were extremely favourable.
We also mounted the new, tiny 12.5mm f/12 3D lens on the camera, which made it look very futuristic, as you can see in the photos below.
