Why not just try it yourself? It's a matter of 5 minutes and you'll see how your particular lens behaves with your camera body.

most lenses are sharper at smaller apertures. you can check "sharpness" ratings at sites like www.photozone.de

I find "sharpest" to be negligible really with these lenses. Shoot at what you went sharp in your foreground and background instead and make the photo you want.

I find f/2.8 is very sharp...
