It's a crowded field in the fast 35mm lens market, and Samyang's approach to make an economical manual focus lens was a wise one: if you don't need autofocus, but want the razor-thin depth-of-field of a fast lens, the lens was already in your crosshairs.

Handling and features This lens is available to fit many different types of cameras, including Canon, Nikon, Pentax, Sony and Four Thirds SLRs as well as Samsung NX mirrorless cameras.
