Sigma 18-125mm f/3.5-5.6 DC

I have been happy with this lens as a "walkaround" lens on my Nikon D50. The photos are sharp and the color looks good. The autofocus speeds are pretty fast, although it probably is a hair slower than the 18-55 kit lens (I tried one in the store) when it has to travel the whole focus range. The AF motor makes a little noise, but I don't find it objectionable. If you use this lens in point-and-shoot mode, you may be bothered by the vignetting at the 18mm setting and f/3.5. The vignetting is quite a bit less at f/5.6, and is practically gone at f/8. I normally shoot in aperture-priority mode at f/5.6, so it hasn't been too much of an issue for me.
