There's a reason a lot of lenses stop down to F22 - it's a usable aperture for slowing shutter speed in bright light. We aren't always chasing maximum sharpness.

That may be a reason, but F22 on most lenses not only represents less than maximum sharpness, images generally looks like garbage. The better way to slow down shutter speed in bright light has always been to use an ND filter. There is rarely a good reason to stop a lens of this format down to f22. Your results will suffer visibly.

Not only does the ND filter allow you to attain better image quality, it allows you to use a sensor in it's better range. Most sensors, even Nikon D800s and D600s, will perform better if they're not being used in extremely bright light.
