Features 1、Camera body adopts all‑metal material, which is very textural, lightweight and easy to carry. 2、Adopting a new generation of shell oxidation process, the lens is lighter in weight, making the size of the lens more delicate than the previous generation. 3、Larger aperture allows more light to enter at the same ISO, thus shortening exposure time, improving picture quality, and maintaining star‑sky or auroraposture. 4、Two ED(low dispersion) glasses, 190° ultra‑wide Angle and F2.8 large aperture, are great advantages for shooting stars. 5、This lens is compatible with M4/3 Mount camera body fit for Olympus.
