[QUOTE="kme, post: 26101, member: 113"] Okay. Photography class 101. This generally goes for still photography, but most of it is adaptable to video. 1. pixels. There are, sadly, a plethora of ways of counting pixels. Effective, extrapolated, interleaved etc, etc. All bull poo! Basically means that the system "guesses" the colour of the dots between the ones it can see, and bulks up the data by a factor of 4, without actually having any more pixels. Forget "1000 X digital zoom". That`s no good either. Zoom needs to be optical. The difference? Digital zoom basically only uses a small percentage of the sensor to collect the data, and expand it to the screen size. Those 20 million pixels WOULD give a good piccie, but you are only using 3 million of em in zoomed mode!!! Memory should be upgradeable. If not, don`t buy! Don`t let the memeory be a factor in the purchase. You can upgrade meme, but not the sensor!! Don`t have 300 different settings, buttons and "special features" that you and/or the end user won`t ever use! Last bit of info: buy the best you can afford. Go for a reputable make, not a QVC "bargain", which is likely to be a lump of tat that didn`t sell elsewhere. [/QUOTE]
