There were a lot of things that I did not like about the camera. Let's start with the image functions.
The camera has the option to shoot in DV mode SD mode and HD mode. What is nice is that the chip is a 16:9 chip or the native aspect ratio for HD is 16:9. The camera has a few issues with it's pans and fast movement infront of the camera. If the camera pans really fast it almost looks like the camera is dropping frames or is trying to catch up but can't quite do it. So on fast pans or when objects that move in front of the screen at a slightly faster than normal pace the camera jitters and the image looks like it is moving at 15fps rather than its 30fps. A rep I was talking with once tryied defending the jitter by saying it looked like the 24p thing people liked in the Panasonic camera - it doesn't and that was a bunch of bull.
The camera has some fairly decent latitude but the biggest problem with its exposure is with the iris and shutter speed. I have told people to imagine a wheel like in The Price is Right, When the contestant spins it only one number is selected, they don't get to choose from the other numbers and have them selected at the same time. Now imagine that wheel has the exposure setting on it: iris, shutter speed, gain. You are only allowed to have manuel control of the choosen selection. So if you want to have manuel control of the iris the gain and shutter speed will default to automatic, and the same for shutter speed and gain - the other options default to automatic - so you never have true control of you picture. When I was shooting one project we had to figure out a different way to tell the story because of the issue, We were shooting infront of a bay window that was at a f/32 and inside was about a f/4. What we ended up doing was forcing the camera, as best we could, to expose to a certain part of the frame - we chose the window because it was the biggest thing in the frame, thus making the actors silhouettes.
The last thing that I could not understand was the green hazing to the frame, it mostly happens in overexposure but happened to us even in normally exposed light, Either way it only happens in the highlights. What happens is a green haze appears on the image, like a digital flare or if it were film, like flashing the film but it turning green instead of foggey, It might not be all that bad if the entire frame had this happen, just fix it in post, but it only happens to portions of the frame. In one shot I was doing an actors black jacket was green on one side and its normal black on the other.
Audio was another issue.
For those who like to run audio straight into the camera, this is not the camera for you when shooting in HD. The only thing the camera gives you is audio meters but you cannot monitor the audio with headphones when it is in this mode. The first project I discovered this, the second one we ran audio from a seperate source so we could monitor audio levels by using our ears - what a concept.
The only difference between the consumer version of the JVC camera and the proffesional version is the Audio inputs and the microphone. On the Proffesional version the put an XLR adapter on it and included a fairly nice shotgun mic. The XLR inputs are not really XLRs, they are XLR inputs connected to the camera through a 1/8" jack, basically a Beach Tek adapter.
Editing is another issue, I ended up doing all of my stuff offline because there wasn't a decent editor at the time I did the projects. CineForm I hear is the best plugin - at least for the PC - and it think it is called Huris (the indie film pack) for Mac. All the info can be found at

I personally will never shoot on that camera again because it limits my story telling.
At this point if you want to shoot on HD I would suggest HDCAM or DVCPRO HD. Or try S16mm film - it looks a heck of a lot better than HD, in my oppinion.
If you budget is only for the MiniDV market, go with either the Panasonic DVX100A or the Canon XL2. And if you are a lover of HDV, then wait for the newer models to come out. The JVC model is a DPs nightmare.
