Probably this issue has been discussed before but here I am again needing the help........I need to buy another digital camera....I have Sony DSC-85 with 4.0 megapixels camera.......I like it very much.....My sister liked it so I thought I will give to her and buy another one for me......So I am looking something in the price range of $400 to $600...it's for personal use not for commercial use as I am not a pro-photographer.....I heard that it's better to have more more Optical zoom and stick with 3 to 4 megapixels and less digital zoom....what makes the difference in having to have digital zoom and (more) optical zoom....I thought to put this subjest in here since I have been seeing lotta good photographer in here......Any input in this subject will be highly appreciated...........
