Hey guys, I am in the market for a Digital SLR Camera. Which one should I buy? My preferences are as follows: 1. Higher the megapixels, the better. But not less than 7mp. 2. More optical zoom, the better. 3. I don't know how realistic this is, but cheaper the better. $500-$700 range... realistic? But then, should I even buy a DSLR? Should I just opt for one of those cute compact ones? What am I losing by choosing compact instead of SLR? I read somewhere that the size of the lens matters, so the pictures with DSLR are better than with Compact Digitals. What do you think? I want to shoot pictures that I can enlarge and hang on the wall as portraits, as well as personal pictures of friends and family that I want to share via web. C'mon, photography gurus, please advise.
