There are lots of great sites out there. These are the ones I use the most:
- NikonRumors.com (I am a gadget head, so have to stay up on all of the latest :-))
- FlashHavoc.com (I like off camera flash work, and this is a great site to learn about equipment and how to use it)
- ByThom.com (Trusted source on reviews, perspective on all things Nikon, and advocate of getting out there to shoot and practice)
- DPReview.com (Great forum discussions)
- B&H Photo and Video (I buy a lot of my equipment there, and loved going to the store when I lived in NY)
