This type of thing is totally alarmist and has no impact in the real world. There is dust everywhere except in clean rooms (the places where they make chips in bunny suits). Even if you use a manual focus prime lens and never change it, you'll still have dust.

I have a well-used D3 and I can't detect any air movement around the viewfinder, regardless of lens use (and I have a number of those types that he complains about).

Even if I'm 100% wrong and there's a boatload more dust on the sensor because of the lens use, what's the worst that can happen? You have some additional post work to do. Your D4 has a sensor shake so that even if there's dust in there, it shouldn't stay on the sensor very long anyway.

By the way, some lenses move their elements a long way for focusing. And some of them move some pretty big elements, and a few of them move large elements a long way pretty fast. An example of the latter is the 400/f2.8 and I'd assume the 600/f4 is the same way. Gee, nobody seems to have complained about those...

I regard the entire issue as a complete red herring.
