GH2 In-camera jpeg image quality (or lack of)

I collected my GH2, I've taken some test shots and I'm taking it back.

The quality of the in-camera jpg shots is much poorer than from my G1. The GH2 clearly has stronger noise reduction resulting in a soft focus effect on fine textured areas, but there's also more chroma noise and it can be pretty blotchy and unpleasent too.

You might like to download and compare two shots taken at the same ISO, aperture and shutter speed on the G1 and GH2. Look at the GH2 shot and you will see blotchy chroma noise in the black velvet square, loss of detail in the cork square and noise / loss of detail in the shadow of the 20mm lens focus ring.

There are some shots in the set at different ISOs and at 400 I really tried to find a way to make the GH2 shine. For example I tried giving it 1/3 stop more exposure (it seems to be 1/3 stop less sensitive at 400 ISO than the G1) and turning on iContrast and iResolution. All these things helped but the results were still not as good as the G1.

That's not good.

I am trying to decide between the GH2, the Nikon D-7000 and the Canon Rebel 16mp for a second camera for HD movies. I have a D-700 but no "crop" Nikon lenses, so I would get a lens with each.

Have you tried the video? What about RAW? My current video cam, the LX3 RAW and video are quite good, but I need a mic jack.

Thanks,

I've had mine for about a week now and love it. I've tested it against my GH1 and can't see a noticeable difference really, certainly now worse. Perhaps it's your particular camera? Or maybe it's not!

Video quality is fantastic. the 24p 24mbit is great, much more details than I can get out of my Canon 7d!

Hi Mike, RAW seems better than JPG and possibly better than G1 RAW but perhaps not as good as GH1 RAW. I didn't try the video before i took it back for a refund I'm afraid. I've now ordered one of the last GH1's as the results seem very good indeed, e.g. using Imaging Resource Comparometer, better than G1 at all ISO's, especially from 400 up. Suspect that Panasonic just put too many pixels on the GH2 sensor.
