Is the FX revolution fizzling?

D600 will sweep up a lot of people who had a D7000 and are looking for better IQ on a budget. In the UK it's only around 400 more than the D7000 intro price for a lot more camera.

It's not a pulse racing camera, it will take time to get going. But Nikon desperately need more FX lenses which are affordable because for me this was by far the biggest investment.

If they don't Sigma may be helping them out...
