Fujinon FE186C086HA-1 1" 2.7mm f/1.8 Fisheye Lens for 5 Megapixel Cameras

The Fujinon FE186C086HA-1 is a 1-inch format, 2.7mm focal length, f/1.8 fisheye lens designed for 5MP and higher-resolution surveillance cameras — delivering a 185° diagonal field of view for full 360° hemispherical coverage from ceiling mounting, or 180° panoramic coverage from wall mounting. The Fujinon FE186 series is among the highest-quality fisheye lens options for surveillance box cameras requiring maximum image quality across the full hemispheric field.

Features

• Focal length: 2.7mm; maximum aperture: f/1.8; image circle: 1" (supports up to 1" format sensors); field of view: 185° (diagonal); mount: CS-mount (with C-mount adapter); designed for 5MP and higher-resolution sensors
• f/1.8 fast aperture provides excellent low-light sensitivity across the full 185° fisheye field of view — at a fisheye angle, light collection at the edges of the frame benefits significantly from a fast aperture vs. slower f/2.0 or f/2.8 alternatives
• 1" image circle supports full-resolution use on 1/2.8", 1/2.7", 1/2", 1/3", and 1" format 5MP and higher-resolution sensors without vignetting — future-compatible as sensor formats in box cameras continue to increase
