Very sharp lens. Very light and relatively easy to handle for hand held use. Controls are easy and intuitive. Extremely sharp. Contrasty optic and did I mention it's sharp, too?

Big barrel may be a handful for smaller hands/people.

Great affordable mid range optic. Very flattering for portrait use. Can't imagine anything being much sharper in this category with 6x7 coverage.
