The 7artisans Photoelectric Fisheye 7.5mm f/2.8 II Lens for Canon RF offers an expansive 190° field of view for distinctive perspectives and creative distortions. Its compact and lightweight construction is perfect for handheld photography, while its f/2.8 maximum aperture allows versatility in various lighting situations. Further optimized with an 11-element, 9-group lens structure, it features a higher refractive index in the front glass group and HOYA ED glass in the rear - effectively minimizing chromatic aberration for improved image quality. The lens elements have multi-layer coatings to reduce flare and ghosting, enhance contrast, and boost color accuracy in stark lighting conditions. Durability is ensured with an all-metal lens body, and the built-in petal-shaped lens hood offers an extra measure of protection for the front element besides controlling flare.
