Samyang SY12M-N
The 12mm full-frame fisheye provides a 180° diagonal field of view and an f/2.8 aperture, with an optical design incorporating three ED and two aspherical elements with Nano Coating to suppress aberrations. Its manual-focus-only build with an integrated AE chip gives full exposure control on Nikon F bodies while keeping weight at 500g. Best for architectural interior photographers and creative shooters pursuing extreme, immersive barrel distortion without needing autofocus or weather sealing.
