photozone.de - Great site and he's building a full frame review database now.


the-digital-picture.com - It's why I'm here and part of this forum. I agree with John, amazing example photos. I like to spend a day with Bryan to learn the secrets of his digital workflow. The consistancy of his images are incredible.


slrgear.com - full listing and many in depth reviews.


My favorite lens comparison interface is the one they've developed over at dpreview. It's a shame the current database is so small.
