heard of a len manufacture by the name of Tokina? I'm looking to replace my stock lens to suffice for my dissatisfied need and the one i have in mind is the Tokina 28-70mm F/2.8 AT-X PRO SV Autofocus Wide Angle-Telephoto Zoom Lens. I'm a little hesitant about purchasing it that is why i'm bringing this topic up.
