Designed exclusively for the Canon RF mount

Optics optimized for the image sensors *1 of mirrorless cameras with the Canon RF-mount are implemented. The lens has a full-frame image circle and can be used with both full-frame and APS-C size mirrorless cameras.

Information communication with the body by electronic contacts

The lens is equipped with electronic contacts and realizes communications between the lens and the body. In addition to Exif information and in-body image stabilization (3-axis) *2, three types of focus support functions (magnification, peaking, and focus guide *3) are all supported.

Versatile angle of view

The angle of view of the 40mm focal length is equivalent to 60mm on an APS-C size camera, making it a versatile lens that can be used as a standard lens on both full-size　and APS-C size cameras.

Manual focus for reliable focus operation

Adopting a full-metal helicoid unit processed and adjusted with high precision and high-quality grease that produces an appropriate torque, focusing with a smooth operation feeling is realized. It enables fine focus adjustment.

Beautiful bokeh effect with 10 aperture blades

A 10-element aperture is used to make the opening formed by the diaphragm blades closer to a circular shape. Out-of-focus areas are rendered naturally, and point light sources are rendered with a soft, rounded bokeh effect.

Aperture click-stop switching mechanism

The aperture ring has a click-switching mechanism that allows the aperture to be opened and closed steplessly without being affected by the click, for example, when shooting video or adjusting fine focusing depth.
