I bought this after much deliberation as to which HD camera to get - I was mostly waiting for an HD camera with a decent zoom - this one has a 25x optical zoom, which is fantastic, but also has a 35x iZoom, which enhances the zoom but retains the HD quality of the picture captured. Having used the camera a few times, the iZoom appears to make almost no difference in the quality of the footage captured - which is a great feature! There is a very decent image stabilizer so that zooming in close to objects doesnt result in shaky video.
There are a few very nice additions, face recognition that will take pictures of any recognised faces (you input these manually first) if they smile while being filmed, so you can get those great moments captured and looking natural - which also brings me to the other great feature - you can take 5 mega pixel stills while filming, they look great and the video remains unaffected; it's probably my favourite feature on this camera as the stills taken are excellent.
The battery life is decent enough, about 1 hour and then some for actual filming, so this could have been better, but the quality of the video is fantastic.
I think it is also important to mention that the camera only films in 1080i format with 4 different bitrates, 5mbps upto about 20 mbps (I think); therefore a progressive scan video is not captured, however, as 1080i is the standard format for HD channels like BBC HD and ITV (or STV) HD it is definately comparable to any HD I've seen so far. The colours captured are vibrant and realistic, and I know that I can be sure that whatever is shown on the LCD screen when filming is what the video will look like on the TV once transferred.
I love this camera, and couldn't be happier with my purchase - it is more expensive than some others, but for what you get the cheapest out there!
In conclusion:
If you want an HD camera with a great zoom, excellent colour capture, lots of extra features and will fit in your pocket (the camera is very small) then you can't get better than this one. I highly recommend it to any home video enthusiasts.
