Hey everyone, I'm having a pretty annoying problem that I've just begun to notice recently I have a Nikon D90 and with my 18-105 kit lens, it seems the pictures aren't coming out sharp or clear at really anywhere around the sides. I know lenses tend to lose quality around the edges, especially at wide zooms, but come on, not this bad. I am concerned, does this mean my af motor and/or lens is damaged?? This was taken with an F/8 aperture (is it just not narrow enough maybe?) at 1/1250 (so the blur isn't camera shake) at ISO250 in af mode, M, with VR on. Please view the full size. Look at the entire left side of the image! including the asphalt, and everything from the left side down, especially the back wheel. Why is this happening? Is it really just that f/8 actually isn't enough? I find that hard to believe with the asphalt so close to the focus point, which is right in the center of the image. The most disturbing is the quality of the road to the left side of the image around the sig. I tried a bit of unsharp mask, but no good.
