Features:

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

Fixed f/11 aperture contributes to the sleek and portable form factor as well as a balanced mixture of depth of field and sharpness.

Gapless dual-layer diffractive optics contribute to a marked reduction in chromatic and spherical aberrations as well as benefit the design of a relatively compact and lightweight lens.

Retractable/extendable design, with a locking lens barrel, offers an impressively compact form factor considering the super-telephoto design.

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

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.

Compatible with optional Extender RF 1.4x and Extender RF 2x teleconverters to further increase the effective focal length.
