*Tokina11-16mm f/2.8 AT-XPro DX* A digital-only 16.5-24mm equivalent, this
versatile ultrawide was introduced in January 2008, but, so far, shipments
haven't kept up with demand. It's fast, well priced ($570, street), and, as
one in Tokina's top AT-X line, solidly built. Best of all, it's one of the
most optically pure digital-only ultrawides we've ever tested.
