It's nice to see that Nikon now have a full frame camera in the Pro-sumer / Wedding photographer's market. The D700. Add a pair of these and a 24-70/2.8 and 70-200 VR and you have a pretty effective Wedding shooter's kit.
It's also very interesting to see that Nikon launched a Full frame 24-70/2.8 a while back too. Which is probably THE defacto wedding lens of choice. I've used one for over a year now and I could easily shoot an entire wedding with this one lens.

Where Nikon are still lacking is in the fast prime arena. That territory is owned by Canon. No one else makes primes as fast or sharp (or as expensive) as Canon. Who else makes a autofocussing 85mm f1.2? Or a 24mm f1.4? That's a whopping 2 stops brighter than an f2.8 zoom. That's 4 times the shutter speed available.

With the launch of the D700, it's easy to see that Canon is in Nikon's targets and it's about time too. I'm predicting a swathe of new fast primes from Nikon over the next few years. With the advent of their new Tilt and Shift lenses it's easy to see that Nikon want Canon's market share. The problem is that Canon have been the market leader for so long, they don't know how to compete any more. A little like a political party that's had a majority share of the votes for so long it can't percive not being in power. So who knows what's around the corner. The 5D is up for replacement in a few months time. But for my money, it's the lenses I'll be investing in.
