Although certainly not the fastest lens (optically or workflow-wise) the SEL55210 is a screaming bargain at $399. The lens is light and compact enough to bring along “just in caseâ€, something that can’t be said of many, SLR tele-zoom lenses. Once it finally focuses, image quality is excellent and the built-in Optical SteadyShot makes it usable even in low light conditions.
