Re: opinion on sigma 120-300f2.8
I did shoot with this lens (I shot with a copy for close to 3 years) ... but I shot with my copy of this lens, not his ... I never had a focus issue with mine - and I didn't think it was slow focusing. That's just my experience with my Sigma 120-300 2.8 .... but if I ever had reason to think a lens of mine was slow to… -
