wide lenses

You dont find 14mm is wide enough for you? I have trouble imagining any situation I'd ever use anything wider than that for video. I imagine distortion gets pretty bad at shorter focal lengths? I have a 11-16 I use on my Canon 7D and never use it for anything wider than 16mm unless I want a crazy effect, maybe 14mm max if I'm doing a 2.35:1 crop... Past that I find the perspective is so distracting especially if you move the camera.
 
The panasonic 2x crop makes 14mm 28mm and with my 10-24mm being used on my canon with 1.6 crop i still found it usefull at times, i also have a 28mm-300mm which i use for wildlife and if an adaptor would work with it it would save getting the panasonic 100mm-300mm, also my canon 50mm f1.8 could be used,selling these lenses would barely cover the cost of the panasonic lens but they would need to work and have control exept for focus which i dont mind manual.

that depends on the lens. As far as I understand aspherical lenses that wide won´t give you the fisheye-look. There will be distortion sure, but a bit wider that 90° (which is approx. 28mm, 14mm on a GH1/2) is helpful in many indoor situations. You´ll be able to get closer to your subject and still see a bit of the environment around it.

I'm not sure about aspherical, but I had a shot ruined by my Tokina 11-16 which does have an aspherical element and I have been under the impression it is regarded as quite good for being a rectilinear wide lens. I shot it somewhere between 11-14mm (<=85deg Horizontal FOV, I dont recall the exact focal length) even with a 2.4:1 crop and the perspective caused a pretty crazy looking forced perspective feeling that made a person on one side of the room look miniaturized compared to someone on the other side just because she was very slightly further from the camera. I can only imagine how much worse it would've been if it wasn't a static shot.

Hey I believe when Arri Master Primes first came out the widest one was 16mm, and I havent yet worked on a job where something wider was needed. Having 16mm or 18mm as your widest is not uncommon in 35mm. I just mean that may say something regarding the usefulness of something wider than 16mm (aka 14mm or so on GH2). I dont doubt there are situations where wider may be needed, but truthfully 90% of the time I never even leave my 24-70 when shooting on my 7D (that would have about the same FOV as a 20-58 on a GH2). Of the remaining 10%, i probably spend 5% on my 70-200, 2% on my 55 f1.2, and 2.99% on my 11-16 at 16mm.

BTW you mention 90deg... wouldnt that be a 18mm on FF35 and 9mm on a GH2? I was basically saying I dont think more than ~75deg horizontal FOV is likely to be that useful for moving images except in rather special situations.
