Product Overview
The 17-70mm F2.8 VC is a compact, fast standard zoom created for APS-C mirrorless cameras. Its broad 4.1x focal range, constant F2.8 aperture, vibration compensation and quiet autofocus make it equally comfortable with still photography and video.
Designed for everyday shooting and travel, the lens balances image quality with portability. A close minimum focusing distance at the wide end opens up expressive detail shots, while weather-resistant construction and a protective fluorine coating support regular use.
