Sigma EX 70-200 2.8 DG APO MACRO HSM problems?

[Ryan_Bibb]

I have a Sigma EX 70-200 2.8 DG APO MACRO HSM and I use it with my canon 5D mark II and I feel that I am having a focusing problem with the lens/camera is there any way I can check this or has anyone had the same problem with the lens?

Thanks

I have thought that there were issues with my Sigma 70-200, but it was always user error. Especially if you're shooting sports it's really difficult to keep the tiny focus square on top of the kid you're interested in. You could google 'd70 focus chart' (I know you have canon - the chart is camera independent) and use that process to check your lens.

Good luck!

Ryan, also make sure that you are on continuous focus when shooting sports....and I would use change the camera to your center spot focusing mode....

Good Luck..
