7Artisans 7.5mm f/2.8 II 8mm
A 190° angle of view and bright f/2.8 aperture define this 7.5mm fisheye, with 11 elements including two ED and HOYA glass elements reducing edge color fringing. The manual-focus lens weighs 540g and spans an 11mm equivalent APS-C field of view, offering an affordable route to creative ultrawide shots. Best for astrophotographers capturing starscapes and VR content creators needing a dedicated, fast prime for immersive 190° panoramas on MFT or APS-C mirrorless bodies.
