Well, I guess there is No Possible Way, to have the same setting for all the cameras, and say, that, one performs better than the other. The thought, itself, is ludicrous.
Also, the same applies, for lighting. For many different reasons. Some cameras have greener (or yellow) shades (hues), and others red. Also, for the same ISO setting, different cameras will show different levels of brightness. Apart from this, the GH2 has a very peculiar characteristic. Very often, you have to switch it on at Higher ISOs and Gradually, lower it to the required ISO, or avoid certain ISO jumps, from certain ISO settings. otherwise it cause noise and some peculiar version of banding. Its some kindda ISO Bug, which is very obvious, sometimes, and not so obvious, at other moments.http://www.personal-...please-look./p1
Tests can never be based on the same conditions. Lighting, or otherwise. If that were the case, all the cameras should have shot the Same video, in the same Format, at the Same Bit Rate, at the same ISO, using exactly the same lenses. Among everything else being constant.
Also, people stating that setting up the GH2 takes long, and is a tedious process, are obviously into the whole studio paraphernalia, where there carry huge Rails, and large Tripods, with huge screens to check everything, and lotsa equipment, and make the humble GH2 look like a bazooka, good enough to bring down an entire city. They obviously have no idea about Indie Film shooting, or using modern day DSLRs, the way they are meant to be.
Having said this, I guess, its every filmmakers duty (whether a DoP, Director or Gaffer), to ensure, that every camera, is allowed to bring out the best results, keeping the Production Limitations in Mind. Imagine using these monstrous sized extras on a GH2, to shoot a film like the Primer or some other Microbudget Indie.It would draw so much unnecessary attention towards itself, apart from the headache of extra crew, extra equipment etc etc.
I guess, taking resolutions to 4k and 5k and 6k, is making film-making more of a technological spoof, and less of film-making. Maybe, much like the 48fps, that Peter Jackson came up with. And, Ironically, its the same people who whine about Panasonic and other new age (Miroorless) lenses being too sharp. That, they don't look dreamy and soft enough.
P.S.: Btw, Please Ignore any, ahem, 'evil thoughts' about the pernicious little weasel (jill, actually). Its her mating season.
