Just posted! Our Sony 70-200mm F2.8 G lens review. Sony's fast telephoto zoom is the reincarnation of a Minolta design which first appeared in 2003, and features goodies such as professional-level build and quiet ultrasonic autofocusing.

So does it justify this premium, and how does it measure up to the standard set by Nikon's latest 70-200mm F2.8 VR II we reviewed last month?
