Bit of a late reply, but thought I would post anyway as it could help a future purchaser from making a mistake
I was thinking about getting another camcorder to replace my old Panasonic MiniDV (GS30 I think it was) which packed up last year, so thought about a HDD one. I don't use it often, so I thought it seemd a convienient solution.
I ordered the JVC Everio GZ-MG155 from QVC, so I could try without obligation (they are great at that) and boy am I glad I did. I really wasn't prepared for how poor the footage would be. I thought with the Megapixel sensor it would have been better than the 130 which only has 800k. I had read a few reviews and they were very mixed, some fantastic, some not, so I needed to see for myself.
I footage was
very soft, focusing & white balance slow to react and the picture blurred when you panned even at moderate speeds and the image was very artificialy looking with very muted colours too. Plus points are that its pretty solid (apart from a couple of plastic covers) and very easy to operate.
My stills camera is a Sony DSC-H1 5MP with a 640x480 movie mode and although the JVC does produce a better picture and in widescreen with stereo sound, its not
that much better and certainly not £300 worth better. I accept that footage from my Sony is a compromise and I am quite happy, but I certainly could not accept the quality from the JVC, so that is going back to QVC.
I did think about getting the Sony DCR-SR52, but I cannot find any professional review on it, so I think I will stick with my stills camera. Pity as I am going to NY & Canada in a few weeks, but I think I will wait until the Hybrid camcorders are better and come down in price, then I can have one item for both tasks.
