Self-explanatory.
You never know!
-mshh's Guide to 'The Sweet Spot'-
Lenses for your DSLRs most definitely have an aperture "sweet spot," or, an aperture that produces the sharpest possible images. This is usually a couple of F numbers (stops) from your maximum aperture (smallest possible F number).
Simply put, if your lens's maximum (smallest F number) is F/5.6, then your lens's sharpest aperture will probably be between F/8 and F/11.
In most DSLR lenses, if you can, try and avoid the extreme apertures. I know F/32 is there, but definitely try to avoid that.
Also, if you're shooting wildlife and want to use a fast shutter speed, try stopping down (using a larger F number) if you have the light available. You might be surprised how much sharper your telephoto lens is at F/8 than F/5.6.
A little about what happens behind my lens...
