180° fisheye lens provides a 35mm-equivalent focal length of 12.8mm, making it ideally suited for interior and architectural subjects.
Fast f/2.8 maximum aperture benefits working in low-light conditions.
Three extra-low dispersion elements and two aspherical elements reduce chromatic aberrations and distortions in order to produce sharper images.
UMC coating improves light transmission and suppresses lens flare and ghosting for more contrast-rich, color-neutral images.
Built-in lens hood also helps to reduce lens flare and surface reflections.
