Sony FE PZ 28-135mm f/4 G OSS Lens

Upon the release of the revolutionary a7S, a need was created for video-focused full-frame optics, and the FE PZ 28-135mm f/4 G OSS lens fills that niche perfectly. The world’s first full-frame lens with Power Zoom (PZ), the 28-135mm also uses Smooth Motion Optics to minimize breathing and focus shifts when zooming. Fine manual control is possible via three control dials for aperture, focus, and zoom. The lens incorporates Optical SteadyShot image stabilization, and a highly capable SSD AF drive motor helps maximize performance of the latest cameras. All this tech combines to make one comprehensive solution for 4K productions that want to minimize lens changes.

Applications: Optimized for full-frame video, the 28-135mm can serve as a go-to optic for mobile filmmaking. The versatile wide-angle to telephoto range combined with a constant f/4 aperture ensures consistent performance for fast-moving productions.
