Samyang 12mm f/2.8 ED AS NCS Fisheye Lens.
The 12mm f/2.8 ED AS NCS Fisheye Lens from Samyang provides a 180º diagonal angle of view on full-frame cameras for an ultra-wide angle, distorted perspective that is useful for architectural interiors, landscapes and creative experimentation in any photographic application. The f/2.8 maximum aperture is effective in low-light situations and enables some measure of shallow depth of field control.
Highlights:
Aperture Range: f/2.8 to 22
Three Extra Low Dispersion Elements
Two Aspherical Elements
Nano Coating System
Manual Focus & Manual Aperture Lens
180º Angle of View
Minimum Focus Distance: 7.9"
Included Petal-Shaped Lens Hood
The lens's sophisticated optical design consists of 12 lens elements arranged in 8 groups including three elements made of low dispersion ED glass and two aspherical lens elements to minimize coma and chromatic aberrations. The Nano Coating System (NCS) lowers reflections to provide increased contrast. Its internal focus system enables its compact design and keeps the front element from extending during focus.
