Features:

Wide-angle prime is designed for use with full-frame Canon RF-mount mirrorless digital cameras.

Bright f/1.8 maximum aperture suits working in difficult lighting conditions and also offers increased control over depth of field.

Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions.

An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to five stops to better enable working in low-light conditions and with slower shutter speeds.

Macro design benefits working with close-up subjects and provides a 1:2 maximum magnification along with a minimum focusing distance of 6.7″.

STM stepping motor offers fast, quiet, smooth, and accurate autofocus performance that is ideal for video recording as well as still shooting.

Configurable Control Ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation.

Rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
