Ultra-wide prime is designed for full-frame Canon RF mount mirrorless cameras but can also be used with APS-C models where it provides a 21mm equivalent focal length.
Two aspherical elements and one ultra-high refractive index glass element help to control distortion and spherical aberrations for improved sharpness and accurate rendering.
Three extra-low dispersion elements are used to reduce color fringing and chromatic aberrations in order to produce high clarity and color accuracy.
Impressively wide 114° angle of view pairs with a rectilinear design, which renders subjects with minimal distortion in order to suit landscape and architectural applications.
Manual focusing design and a minimum focusing distance of 10.6″ suits working with close-up subjects.
Built-in petal-shaped lens hood helps to prevent stray light from causing lens flare and also offers some physical protection to the lens’s front element.
Front of the lens is threaded to accept optional 52mm filters. The lens is also compatible with an optional, dedicated 100mm filter holder.
Five-blade diaphragm produces distinct 10-point sun stars and specular highlights when stopped-down and photographing point light sources.
