Worth Knowing
−No optical image stabilization (OIS); reliant on in-body stabilization
−Reduced aperture at telephoto end (f/4.8) limits low-light performance compared to constant f/2.8 lenses
−Corner sharpness at wide end (16mm) slightly soft wide open; corners not as sharp as premium f/2.8 alternatives
−Some sample-to-sample variation in centering quality reported by users
