Sigma 70-200 2.8

[stpierre87]

Does anyone else own this lens. I use it with my nikon D7000 & D90 and the auto focus just never seems to work right. My focus point always seems to be blurry. I always keep my shutter speed high and my ISO low. I use back button focusing and always make sure I'm using the right auto focus setting. Anyone else having this kind of trouble or does anyone have any kind of advice on whats goin on.

i've got a 70-200 apo ex hsm........no problems at all.bought it used here.i also have 24-70 ex dg.Again bought used here,no problems at all.After uying these,i started noticing people remarking that they are a good lens if you get a good copy.Perhaps i was lucky,but it sure has me hesitant on buying a used Sigma ultra-wide.I'm also using the D7000

I think the 24 - 70 is my next lens. I think I may rent it first.
