Title: very disappointing
Review: AF was extremely slow, even in good light. I tested it against another Sigma lens, non-HSM, with similar minimum aperture. The motor sounded underpowered, even with a freshly charged battery in the D70s.Shots were sharp and nicely contrasty, when I used manual focus.
