Combining a wide-angle perspective with a fast maximum aperture, this 21mm f/1.4 Lens from Rokinon is designed for Canon EF-M mirrorless cameras and provides a 33.6mm equivalent focal length. One extra-low dispersion element and a trio of aspherical elements are incorporated into the lens construction, and help to control aberrations and distortions for increased clarity and sharpness. The bright f/1.4 maximum aperture excels in difficult lighting conditions and also enables greater control over focus placement, which is further complemented by the manual focus design and rounded nine-blade diaphragm to produce a quality of bokeh. Additionally, an Ultra Multi-Coating has also been applied to all lens elements to reduce lens flare and ghosting for increased contrast and color fidelity when working in harsh lighting conditions.

Bright f/1.4 maximum aperture is ideal for working in low-light conditions and also offers greater control over your focus position for selective focus applications.

One extra-low dispersion element and three aspherical elements are incorporated within the lens design and help to control chromatic and comatic aberrations, as well as reduce color fringing, for sharper, clearer imagery.

An Ultra Multi-Coating has been applied to all lens elements in order to suppress lens flare and ghosting for increased contrast and color accuracy.

This manual focus lens has a non-rotating 58mm front filter mount to better enable the use of polarizing, graduated ND, and other filter types that require precise positioning. Additionally, its internal focus design maintains the overall length of the lens during use.

Rounded nine-blade diaphragm contributes to a pleasing out-of-focus quality when using selective focus or shallow depth of field techniques.
