Here is a list I have compiled of sites that I venture to day by day and by far the best for learning photography, reading reviews/ratings, and learning the digital techniques.

Reference

dpreview.com
Best overall site where you can compare cameras side by side and also get the latest news.


pbase.com
Want to see some shots taken with your lens or lens you're shopping for? Can't beat this site.

Fred Miranda
Want to pick out the best lens for the money? Read what others think. As well as learning photoshop techniques.

Imaging Resource
Has videos and more, if you want to get a second opinion on things.

Shop

B&H Photo
Amazing selection, and usually full of rebates, usually the number place to shop.

Adorma
It's a tad overpriced, but chances are if you are looking for an accessory you may have to shop around, keep this site in mind.


*More to come

Dpreview is awesome, great reviews and previews, and informative, knowledgeable, informative forums. I'm on the forums all the time.

Pbase is great for looking at great photos, plus the best thing about it, is you can click on a certain camera or lens and see pics from that camera or lens!

Nice post man I'll sticky this

I'll throw in another vote for FredMiranda. Their forums are awsome!
