The build is sturdy, hand-feel is right-on, and our first impressions of the Image Stabilizer and face detection are "impressed." Under stage lighting, no flash, at high ISOs, at supertelephoto, at slow shutter speed, exposures in Face Detection were right-on. And the floating lens elements of Mega O.I.S. produced a lot of long-reach keepers, even under less-than-ideal lighting. Stage lighting is challenging even for experienced photographers, and it can easily fool metering systems, but the Face Detection usually tracked and exposed the images correctly once it locked onto a face in the frame.
