I'm looking to buy a new Digital camera as after bringing my current one into work for the past 3 years, one of the kids managed to push a button on it and it's gone all up the left 
Anyway my current one is only 5MP and to be honest is a great camera, only problem was with it was that it doesn't take great photos at night time on holiday etc. So have been looking at 2 cameras on teh Argos site a 8MP and a 10MP, but not sure which one is better. For a start what's the difference between optical zoom and Digital zoom
Here's the 2 that I've been looking at http://www.argos.co.uk/webapp/wcs/st...79_1500234959_ any help would be appreciated
