Lens Overview — Yasuhara 180

The Yasuhara Madoka 180 is a circular fisheye prime lens designed for Sony E mount mirrorless cameras with APS-C sensors. Built around a 7.3mm focal length, it delivers a full 180-degree field of view in circular fisheye format — the kind of immersive, all-encompassing perspective that makes it a distinctive creative tool for photographers looking to push beyond conventional wide-angle imagery. The lens is manual focus only, with no autofocus capability, putting full control of focus in the shooter's hands.

With no image stabilization on board, the Madoka 180 keeps its feature set lean and its physical footprint compact, weighing in at just 200 grams — a sensible match for the lightweight Sony mirrorless bodies it pairs with. The maximum aperture is f/4, which sets expectations appropriately for a specialty fisheye of this type. There is no filter thread, consistent with the extreme front element geometry typical of circular fisheye designs.

Whether you're shooting architecture, skies, or experimental creative work, the Madoka 180 offers a focused and deliberate approach to ultra-wide circular fisheye photography on the Sony E mount platform.
