Originally posted by Sandy Hancock Have you seen a head-to-head comparison to base the supposed superiority of the Tamron? I suspect the difference would be hard to pick.
Consider the older, non-OS Sigma if you want to save a few bucks and still get HSM, quick shift and the wonderful EX build quality(and the zoom ring in the right spot).
Hi Sandy
No i haven't, just heard the tamron has better IQ. Do you have any experience with either lens that you could share. For me personally, if you don't have good AF whats the point of good IQ cus you may end up with a blurred shot or miss it altogether.
Sigma owners your thoughts please!
