I mean "action photography" - sports, birds, etc... whatever moves fast shot by non-professional photographers I say this because: 1) The current range of telephoto lenses is either non-stabilized (300 F/4) or horribly expensive (300 F/2.8, 600 F/4, etc...), while Canon has some pretty great stuff, such as a 400 F/5.6. Will Nikon ever release a 400 F/5.6? 2) The new FF model has a zillion of megapixels and a fairly low speed burst rate (6 fps). What about an "amateur D4"? No matter whether APS-C or FF, is it ever going to be released? Apparently not, given that the D400 is expected to have 36 MP too. I'm not complaining (I have a lot of fun with my D90 and I'm not planning an upgrade), but I'm a little surprised. Few years ago, there was the D300 and Canon had not released the 7D yet. The situation was opposite: Nikon had made a camera for amateur action photographers. Canon would only follow years later. Now it looks like the cheapest Nikon camera specifically designed for action costs 7,000 dollars. What do you think?
