I totally forgot that the VG20 existed haha
Im on the fence with both Nex 7 and VG20..need to see more about them.

Yeah the overheating is my only real problem with it.

Its a design flaw in keeping the camera so small...its also pretty random when giving the warning sign (maybe software problem?)...but keep in mind the 5n wasnt really designed for long pro video shoots.
People keep forgetting this.

I have noticed if you keep the lcd tilted up/off a bit delays the overheating....also heats up quicker in 50p mode than 25p mode.

I wonder if the 7 will do the same? nobody has reported it yet.

I tried 3rd party batteries but no luck - the 5N won't accept them. But then I see other people saying they can. Strange.

FUCKING EH!

My Nex 5ns lcd screen died when I switched it on this morning...not impressed as camera is only a month old. Now having to send to sony repairs. But can use the evf okay.
First time ANY camera has played up on me.

Another thing. If one really wants to use 5n for shooting events e.t.c. it's very possible to have 2 or 3 spare bodies considering the price point, to avoid the overheating issues.

I've recently used the 5n for a couple of gigs.. All in all, it has some cons which are well covered here (aliasing, moire, overheating).. That said, it's a very good compliment to the gh2. Better for shooting wide, no banding (very good DR) and more video settings to choose from - the gh2 on the other hand can give a more crisp image for highly detailed scenes and scenes where aliasing or moire could be a problem.
For a showreel, I used a gh2 coupled with a 1.5x anamorphic adapter in 720p50 (which gave very limited wide options, but plenty in normal/tele/supertele end, aswell as surprising macro capabilities with the gh2 kit lens) , coupled with 1080p50 from the 5n, which will give the possibility to crop the 5n footage to the same aspect ratio as I can get from the gh2..

Obviously, one has to take care with certain types of shots to avoid aliasing and overheating was an issue during a long take - I had to switch the camera off for 5 or so mins after about half an hour (same as the limit anyway) and then I could shoot again without interruption for the additional 15min I needed.
It would be a mistake to only have the 5n to shoot an event where the camera needs to keep rolling, but it works great for additional footage in such circumstances.

Another big plus IMO is smoother handheld shots than from the GH2. Its not really sensitive to vibrations e.t.c. which is one of the major drawbacks with the GH2 - so also in this sense they complement each other very well.

Those are my initial impressions, using only kit-zoom and wide pancake. (I didn't have time to get adapters!)

I'm sure I'll bump into some more issues in post.

Very good value for money. I'd pick it over the canons any day of the week.

Hey Vitaliy have you made any progress with a hack?

It would be really cool to mount the 5N on top of the 5D and shoot 60p and 24p simultaneously. But @ 28Mb/s the 60p is too compressed for my liking.

So, I've been using the 5N to show an online travel show for the past two weeks.
It's a great, nifty camera. Great quality and compact. I average 2 hours footage per day, and have so far never used more than 2 batteries (I have 3).
But by far the biggest issue is overheating. On a cold start I can clock in about 28 minutes of footage. It also seems to overheat at a faster rate thereafter. You would need to leave it alone to cool for say, a good few hours before being able to record that long again in one go. We had to do interviews so I would never use the 5N for such a situation again (luckily I was B-cam). I think the 5N is best used for 'fun' or quick professional shoots.

Here's me leaving the 5N to cool after a long shoot:

Sony seem to think it is compatible http://www.sony.com.au/product/clm-v55

@Dalefpf you let me cooled! I ordered a v-55 for a 5n rig, and now doesn´t work? F**k.

@ Dalefpf How is the moire and aliasing look - to bad about the v55's
