Difference in video from NEX 3 - to NEX 5 - and now NEX 5N????

I don't care on bit about shooting photos (Already shoot Sony A850) but am interested exclusively in NEX as a video camera for shooting music videos.

I know there's supposed to be some difference/improvement in the NEX5 over the past models - but-

Is there any difference in the 3 vs 5 models? No one seems to be talking much about NEX video online. :/ They mostly go on about the stills. There are only a few very good video demos - but mostly from Sony employees (massive resources/skills to produce). We are hoping to get the closest possible "film look" in our shoots...lots of bokeh and smooth movements.

If I got the 3 and used it at the highest resolution - is it the same and the 5?

Biggest concerns would really be stabilizing such a small camera - including zooms and focus moves, hand held or on a mount. *Fitting it on a crane with any kind of remote control might be hard too. Also syncing music in post is a concern (though it should be easy in FinalCutProX w/reference tracks on the video - but NEX5 has no audio inputs only a mic).

Would going to a dedicated video camera just be smarter to get better I/O and not hassle with changing lenses?

Thanks in advance for input!

 

Thanks much - I did find more info -
the 3 has MP4 HD 720/30p -
the 5 has - AVCHD 1920x1080/60i 1920 x 1080 (60 fps), 1440 x 1080 (30 fps), 640 x 480 (30 fps)
the 5N has - AVCHD 1920 x 1080 (60 fps), 1440 x 1080 (30 fps), 640 x 480 (30 fps) -
and the yet to be seen 7 will have - MPG4 1920 x 1080 (60, 24 fps), 1440 x 1080 (30 fps), 640 x 480 (30 fps)

I'm not sure what the 7 is MPG4 and not AVCHD unless the spec I got was wrong.

 

Thanks for the replies -

The stabiliser issue could be something to look at as a consideration though I've not heard that one as a negative before concerning video shooting...
As far as I know there are at least a couple of assignable soft buttons for manual control?
I had heard about the clicking issue but from what I also heard - it was fixed? Will have to look into that one more closely.
By Film Look - I meant 35mm motion picture film - not camera film.

The Panasonic GH1/GH2 DSLRs are used a lot in filmmaking interestingly - but I really don't think a full size DSLR is the way to go. The NEX seemed interesting more as a digital back for video, but true, it isn't a full on video camera like the FS100 (at 10 times the price!). Even VG10/VG20 are 3x the price...

I should mention I'm getting this for a beginner (22 year old son) to get his feet wet with. The lens interchangeability is great - but also a black hole for money which he doesn't have. LOL I live in another state so he won't be getting to borrow my premium glass either.

Anyway thanks again for the discussion!

 

Also - another new model - an update to the "3"

C3 - video specs
• MPEG-4 • 1280 x 720p 29.97fps (9 or 6 Mbps) • 640 x 480 29.97fps
