I thought my Nikon 18-200mm VR took pretty sharp images until I started using Dxo Optics. Here is an example I took yesterday with my D80 and 18-200. The EXIF data is included. Post processing is so much sharper I'm concerned my lens is not as sharp as it could be. I would appreciate comments on whether it's my lens' softness or Dx0's greatness. This discrepancy seems to present frequently. I've just ordered the new Sigma 18-50mm f/2.8 to help me shoot indoors with out a flash. If it turns out the 18-200mm is soft I'm may sell it and get a Nikon 80-200mm f/2.8.
