Rokinon 8mm f/3.5 HD Fisheye 8mm
The manual-focus 8mm f/3.5 lens captures a 180-degree fisheye view on APS-C sensors, with sharp, controlled flare from its 10-element optical design and hybrid aspherical element. A multi-layer coating and removable petal hood further reduce ghosting, while the 12-inch close focus enables dramatic, distorted near-far compositions. This lens suits APS-C shooters needing an affordable, compact creative tool for extreme wide-angle landscapes, architecture, or experimental video.
