Hi, I got a Sigma 2.8-4 / 28-105 on Nikon F100. The problem with the lens is, that the autofocus need two times run to focus on an object. Has anybody the same affect / problem with this lens on the F100? IT's urgent! Help me! Thanks! Harald

Same old story: Expensive camera, cheap lens. Sigma and other 3party lenses face many mechanical problems on the brandnew pro-bodies like F100 and Canon Eos 3. I suggest to trade the Sigma for the wonderful 28-105/3.5-4.5 Nikon lens. Original lenses don't have this kind of problems. A bit hard to swallow, but the truth.
