Sigma 17 70 2.8 4.0 OS?
Oct 25, 2012

I have had this lens for about 4 months, and as a general rule I really like it, but! i have one complaint, and wonder if I'm alone or common to this lens.

In lower light its slow to acquire focus and lock on! bright light fine, but shooting in "shade" or shadows it has a tendacy  to "hunt" back and forth and sometimes it does not get focus.

Is this common to this lens, or just mine?

Thinking to spring for the "real deal" 17 55 2.8 and be done with.
