The Sony E PZ 16-50mm F3.5-5.6 OSS is a variable maximum aperture standard zoom lens for the Sony E-mount, announced by Sony on September 12, 2012, and released January 2013.

The lens features a compact construction colloquially referred to as a "pancake lens" and a micromotor-driven power zoom controlled by a switch on the side of the lens and the dual-role focus/zoom ring when the camera is not set to manual focus.

Given the lens' focal length of 16-50mm, it is generally regarded as a multipurpose lens, though underperforms in low light situations due to its slower variable minimum aperture of f/3.5-5.6.

Through the in-lens corrective programming, chromatic aberration and vignetting are reduced by the camera.

Vignetting always remains visible with uniform backgrounds, especially at 16mm and always requires out-of-camera correction for applications like product photography.
