The 17-70mm F/2.8 Di III-A VC RXD (Model B070) is a fast aperture standard zoom lens for APS-C mirrorless cameras. It’s engineered to deliver both a broad zoom range and excellent image quality. With a focal length range of 17-70mm,1 it achieves a 4.1x zoom ratio, class-leading for an APS-C standard zoom lens, while maintaining a fast, constant maximum aperture of F2.8. The 17-70mm F2.8 VC includes VC (Vibration Compensation), and a fast, quiet AF2 system. With focus breathing and AF noise effectively suppressed, the 17-70mm F2.8 VC is optimised for both stills and video shooting.
Despite offering a class-leading zoom ratio and VC, the 17-70mm F2.8 VC remains notably lightweight and compact. This makes the 17-70mm F2.8 VC an outstanding choice for daily use, as well as for travel where minimising weight is essential. Excelling in close-up work, the 17-70mm F2.8 VC achieves an MOD (Minimum Object Distance) of just 0.19m (7.5in) at the wide end. Capture unique, expressive images in a variety of everyday scenes, including street photography and portraits. Functionality and versatility are enhanced by features such as Moisture-Resistant Construction and Fluorine Coating. In your everyday life and on your trips to distant places, the 17-70mm F2.8 VC captures all the excitement and discoveries with the finest possible detail.
