Lens Description

The Samyang 21mm F/1.4 ED AS UMC CS is a normal prime designed for cameras with a APS-C (1.5X) sensor. This ultra-bright prime has a 21mm focal-length. It provides the same field of view as a 31.5mm lens on a Full-Frame camera.

This prime can focus down to 28cm 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.

This lens has a Sony E mount. It directly attaches and is fully compatible with all Sony E mount cameras with APS-C (1.5X) sensors. Samyang also makes this lens for Fujifilm X, Micro Four-Thirds and Canon M mounts.
