I ordered the D800 in February from B&H and it arrived in late July. After a weekend shooting soccer, I must say it seems like it was worth the wait. First, I must admit I have to grow accustomed to a 4 frames per second frame rate in FX mode (highest resolution mode). With the vertical grip attached to my old D700, 8 frames per second is a nice added feature. I ordered the vertical grip with the D800 for the added battery capacity. However, unlike the D700, the D800 still only shoots 4 FPS in FX mode with the attached vertical grip.
Are there any other other reasons not to like the D800? Absolutely not! Autofocus speed is better than my D700 with the same Nikkor 300mm f/2.8 lens attached. And picture quality is outstanding. In fact it's much better than anything I've ever experienced. One of the main reasons for purchasing the D800 for sports is the ability to crop and maintain significant photo clarity. For me, that means not worrying about the reach of my 300mm lens when shooting soccer. Check out the first photo below. This was shot with the D800 and 300mm lens. The photo was cropped significantly and straightened as well. I think the photo clarity is outstanding. Compare this to the original 36.2MP (28.81 MB) RAW file at the bottom of this post.
