i have never shot with my 400/2.8 at any aperture other than f2.8. there
isn't any point with a lens of this type. if you could use a smaller
aperture, you wouldn't need that lens. also, if Pentax did what other
manufacturers have done, it is designed to perform best wide open.

I was trying to keep the shutter speed up, these were shot at ISO 400, at
around 1/1000 second. The aperture was close to wide open, around f/6.3.
