7Artisans 4mm f/2.8 Circular Fisheye 4mm
Delivering a 225° circular-fisheye view on APS-C (6mm equivalent) with an f/2.8 aperture, it captures low-light scenes with pronounced distortion. Weighing just 201g and featuring a de-clicked aperture ring, the lens pairs naturally with gimbals and drones for smooth video iris changes. It’s best for macro shooters working at its 3.3-inch minimum focus distance and panorama creators stitching 360° spheres from two shots.
