When I first started shopping for a digital camera and ended up buying my E550, there were two sites I found invaluable.
DPReview gave fantastic information about all the cameras in the market, ranging from my little point and click through to the market leading pro DSLR's of the day. I used this site again when buying my 400D and was glad its only got better with age.
If you've ended up here and are thinking about buying a camera, then go there next.
I first came across
Chromasia via an article in the Financial Times I think. the daily pictures are amazing. Of all the sites on the web, of all the pictures out there, David Nightingale is the person who drove me to do this. I've never spoken tot he man, never exchanged an email, never posted comments on his site, but I think his work is fantastic and if I ever get to be half as good I'll be happy.
