I'm going to Florida soon and want to capture the experience. I'm a bit of a Sony freak I'm afraid so I've turned to them in the first instance but I can't find anywhere that explains the differences and pro's and con's between their models. I'm looking at three - the SR72E, the SR190E and the SR290E. I'm not particularly worried about price but obviously don't want to spend more than I need to. I'm a bit confused though as the more you spend, the less HDD space you get and the lower level optical zoom you get. Can anyone explain? My main concern is sound and image quality. Can anyone tell me what the difference is between Image Device: Size 1/6.0 & 1/3.0 ClearVid CMOS sensor? And the difference between Interlace and Progressive? Also the difference between Carl Zeiss Vario-Tessar lens and Carl Zeiss Vario-Sonar T*? Basically I'm interested in image quality, sufficient optical zoom for amateur needs, and a HDD big enough to cope with 2 weeks in DisneyWorld. Sorry to ramble on, any advice would be greatly appreciated!
