7Artisans 7.5mm f/2.8 II 8mm

Its expansive 190° angle of view and f/2.8 aperture create extreme, creative distortions in a compact 265g all-metal body. The optical design uses 11 elements with 3 ED glass and multi-layer coatings to suppress flare and chromatic aberration for cleaner images. This manual-focus lens is best for APS-C shooters wanting an affordable entry into dramatic, ultra-wide fisheye photography for landscapes or experimental video.
