Lello,
Initial thought is aperture. The 18-200 is f3.5 to f5.6. In this case that means f3.5 is the widest aperture at the 18mm end and f5.6 the widest at the 200mm end. For a lens of this zoom range sharpness will increase as the lens is stopped down. MTF tests that I have seen suggest f8-f11 for this focal length.
The next question is severity of crop. It also appears to be a low contrast situation so you do not have that extra boost that enhances apparent sharpness.
I will have a net search for some reviews and then come back with possible test suggestions unless someone beats me to it.
