Are you using One Shot auto focus? If you're using AI-servo I could see the focus behaving as you describe.

I'm not familiar with that particular lens. Some older Sigma lenses simply do not work correctly on newer camera bodies or digital bodies. This is very much the case with both Canon and the Minolta/Sony A-mount. I shoot with both systems and can safely say a lot of Sigma products are hit or miss.

Hi

thanks for the answer

i use one shot auto focus

i can post some photos so you can tell me if they are sharp enough
