The Porst Uni-Zoom 35-105mm f/3.5 Macro MC Auto M is a manual focus multi-coated lens with a fixed lens speed throughout the entire range of focal lengths. The lens offers a minimum focusing distance of 1.35 m and from 0.15 to 0.6 m in macro mode. It also features a black 6-blade diaphragm, perture range of 3.5-16, and M/A instant-return aperture mode selector. Zooming is controlled with the ring. The lens retains sharpness while zooming, which is very important for shooting HD video. Filter thread diameter: 72 mm.

This versatile zoom lens produces a good picture with bright colors and excellent sharpness and is suitable for any type of photography: from portrait to nature and architecture.
