I've been having a conundrum lately with one of my new lenses. I got the 18-200VR at Christmas, and was very happy to pick it up. However, it seems EVERYTHING I shoot with it is soft as soft can be. Far much more so then my 18-70 that was the kit lens I was using before hand. I'm just curious, how can you really tell if its a lens problem, or is the lens naturally soft? If it is a problem with a specific lens, can you do anything about it? Send it to Nikon? Warranty?

I haven't had much vignetting issues, atleast none that stood out worse to me then the overall softness. I'm having to do so much extra sharpening to my photos in post-processing, its damn near making them unusable.

How do your prints come out? If they are acceptable at around 11x14 or slightly larger, I wouldn't worry unless you primarily display your images on the web. Trying to judge an image on a screen can be futile.

It's a general rule that the more range a lens covers, the poorer the optical performance will be, however there are exceptions. 18-200 = 11.1 zoom. Also if you want sharp images you usually have to step down the lens, typical sweet spot is around f/8 to f/9, at 500mm I have to shoot f/11 with my sigma 170-500. Prime lenses seem to be sharp at all f/stops...
