Overview

The Yasuhara Madoka 180 7.3mm f/4 Fisheye is a compact, all-manual circular fisheye for Sony NEX, offering 180° field of view. Optically, center sharpness is outstanding wide open, but edges soften to fair levels; stopping down to f/8–f/16 improves overall sharpness. Chromatic aberrations are well controlled, with minimal fringing. Build quality is solid with plastic and metal, but the undamped focusing ring is easily knocked off focus. It suits creative photographers seeking a portable circular fisheye for mirrorless cameras.
