With an expansive 185° angle of view, the Canon RF-mount 12mm f/2.8 Fisheye Lens from AstrHori is an all-manual lens capable of producing unique perspectives and creative distortions. It's particularly well-suited for capturing the starry sky, thanks to its large f/2.8 aperture, which helps reduce noise in low-light conditions. With an optical design of 11 elements in 8 groups, this lens effectively combats image degradation at the edges and improves edge-to-edge sharpness. Waterproof multilayer coatings have been applied to individual glass elements to suppress flare and ghosting for improved contrast and color fidelity when working in strong lighting conditions. The lens has an all-metal body and features a built-in petal-shaped lens hood that also helps reduce flare while protecting the front element.
