I believe poster #1 covered most points re. technique. You probably realize that sharpness below f/5.6 already starts to decrease. In my experience, the 14-24/2.8 is the sharpest among your zoom lenses. Only high level Nikon or Zeiss primes might be sharper. I presume you use LiveView in MF mode; I find the Nikon AF lenses kind of difficult to focus manually.
