Yeah, different tools for different jobs. But Nikon used to have the BEST tool for every job, not just one tool that works OK for everything. A 400mm/f5.6 with image stabilization would be better than a 400mm/f2.8 for SOME things, and a 400mm/f2.8 would be better than a 400mm/f5.6 with IS for SOME things. It would be nice if Nikon would give photographers a choice of what lens to get for their intended purpose. Frankly, I want the 400mm/f2.8 not because it's a fast 400, but because with a TC-20E it's an AF 800mm/f5.6 that focuses CLOSE. Unfortunately I'm not one of those guys for whom $7500 for a lens and TC isn't a lot of money, so the 400's got to wait a bit. -Don
