Aperture is next for sharpness. Wide open is worst and on the other end completely stopped down causes defraction to blur images. Most cameras opt for more light when auto focusing so they are aist wide open. So again a tripod might just be what is necessary to get the exposure and resolution desired.
Check out dpreview.com for their l ens comparison tool. It is a good starting point for understanding the resolution of lenses.
Andy When it comes to sharpness so many things affect this beside the lens. First and foremost maybe how you hold the camera or even better ARE you holding the camera??? Sharpest pictures are usually on a tripod or monopod. If you are hand holding the camera have you got it in a position that is as solid as it can be? So many using point and shoot cameras are holding out from their bodies with no real support, and they wonder why their pictures are blurry. Then there is what you do with the images in post processing. Most digital cameras require at least a little sharpening in an image editing program, and it takes a little time and effort to figure out what you need. It is easy to go too far. Others may have other ideas to try before you buy lenses.

I'm using a Nikon D-80 with an 18-55mm lens. I would like sharper images. I'm wondering if anyone is using the the Nikkor 50mm f/1.8D AF lens, the 50mm 1.4, or the 35 mm 1.8? Are these significantly sharper?
