The Samyang 20mm F/1.8 ED AS UMC is a normal prime designed for cameras with a Four-Thirds (2X) sensor. This ultra-bright prime has a 20mm focal-length. It provides the same field of view as a 40mm lens on a Full-Frame camera.
This prime lens focuses down to 20cm from the imaging plane. The lens is not capable of autofocus and so the focus-distance must always be manually adjusted via the focus-ring.
The lens weighs 530g.
This version of the lens has a Four-Thirds mount. It directly attaches and is fully compatible with all Four-Thirds mount cameras. Samyang also makes this lens for Canon EF, Nikon F, Pentax K, Sony A, Sony E, Fujifilm X, Canon M and Micro Four-Thirds mounts.
