Doug (I wish Clive had said it, but he's at Cannes and someone had to say it) ... sorry moderators.
LOL... Am I getting a reputation? (Oh, and I'm not at Cannes until Sunday)
Picking the right camera to make a film for international release is a complicated issue... and as everyone has pointed out, you're coming at the question from the direction.
There is an ever growing list of films shot on camcorders not originally designed to make feature films:
FILMS SHOT WITH VX1000
==============
Visitor Q
In The Family
Bamboozled
Dancer in the Dark
Waking Life
The Cruise
FILMS SHOT WITH OTHER PROSUMER CAMERAS
=================================
Chuck & Buck
Julian Donkey Boy
The Idiots
Last Call
Blair Witch
Open Waters

Now, all of the above films were shot on standard def cameras... and the cameras you quoted are all Hi-Def.
In theory, a good DOP could make a feature film with any of them.
However, the truth of the matter is, cameras play only a very small part in the overall success of a movie. You can shoot on pretty much anything, provided you have an absolutely stunning script, a camera operator who knows how to get the best out of the camera, a director who knows how to get the best out of a cast and also understands the limitations of the camera... and finally an editor who can both cut the movie into something special and at the same time understands the best workflow to get the most from your footage.
What I suggest is this... don't worry about the camera. Get your script nailed. Make it the best script ever. Then find incredible locations. Then find a professional camera operator and an editor and sit down with them, Show them the script and the locations... let the two experts decide which camera is the best for the job, working to the budget you've allocated.
Too many independent film makers see buying a camera as the first step. It shouldn't be. Make decisions about the camera when you're ready to shoot... and let your team figure out what they need.
There is another reason for doing this. HD camcorders are improving in quality and coming down in price. If it takes you a year to get your script and team together... well, by then God only knows what you'll be able to buy for the same price. Not only that, professional camera rigs are evolving as well. In a year's time you might be able to get a professional, second hand, Varicam for the same price.
Finally... (and Oh God am I getting tired of typing this one)
As a friend I'd like to suggest you go back and edit your last post. Most of the guys here are American and they all love their Mom's. This is a business that only survives on goodwill and the sharing of expertise. Doug is one smartest guys on here when it comes to post production workflows and keeping high quality images in post production. Chances are you're going to need his advice at some point in the future.
Even if you don't agree with people, it's better not to post in anger. (Unless you're me... the Dr. House of indie film making LOL)
