GH2 GH1 vs GH2 in normal room situation. Surprise!?!

Hi,

I just unpacked two GH2s. Pointed them at things in the room. Their video image seemed to me a bit darker, than what I was used to with my GH1. So I take out the GH1 mount the same lens, put them side by side, set them to identical settings (same profile/mode, ISO 160 @ f 3.5) and voila: Not what I expected.

Granted the GH2 will render colors better in very low light (have seen it, but not tried it) and it makes blacks blacker here, I'm surprised the image is actually significantly darker overall. Note: I tired both GH2s with the same result.

Anyone else experience that? Or am I just missing the obvious reason for why this is the case? That I have to shoot ISO 800 on the GH2 just to match ISO 200 on the GH1 under normal lighting conditions, was not what I expected.

Greetings,
Johannes
 
Hmm that is very interesting...would love to hear from those who have the camera what they think.
This is the first time I'm hearing anything about this.
 
I thought I read that the ISO measurements are slightly different between the two, so that the GH2 ISO 160 is really closer to what ISO 100 would be like on the GH1.
 
Thanks id4alexey,

you read and read review after review before getting a camera and when you get it, it still surprises you.
 
The ISO scale is different, yes, but another factor is the change in color profiles.

ISO 800 on the GH2 to match the GH1 would be very unusual. I shoot with both and I do not get that at all. My experience is more like that represent on the ISO Sensitivity charts at the http://www.dxomark.com/index.php/Cam...2%29/Panasonic link that id4alexey provided earlier.

The statement that the GH1 has higher ISO sensitivity is technically accurate, but also potentially misleading regarding video. You do have to specify higher ISO numbers on the GH2 but the noise performance in the video is better and it can extend to higher ISOs (even in video mode with the hack). The shadow performance has also improved.

I often shoot the two side by side.
 
This doesn't surprise me at all. The GH2's forte is dark and sinister. Bring it out in the light of day and it falls down dead :)

Cheers,
Pete
