Canon RF135mm F1.8 L IS USM Lens

The Canon RF135mm F1.8 L IS USM is a premium L-series telephoto prime lens designed for Canon EOS R-series full-frame mirrorless cameras. Its combination of a 135mm focal length and bright f/1.8 aperture provides excellent subject separation, beautiful background blur and exceptional low-light performance.

Designed especially for portrait, wedding, fashion, sports and event photography, the lens delivers sharp, detailed images while producing smooth and attractive bokeh.

The built-in 5.5-stop optical Image Stabilizer helps photographers shoot handheld in challenging lighting conditions. With compatible EOS R-series cameras featuring IBIS, the combined stabilisation effect can reach up to 8 stops.

Its Nano USM autofocus motor provides fast, smooth and quiet focusing, making the lens suitable for both photography and video applications.

The optical design incorporates three UD elements along with Canon's ASC and Super Spectra coatings to help control chromatic aberration, flare and ghosting.

Optical Performance

The 135mm focal length is particularly well suited to portraiture because it provides flattering perspective compression while allowing substantial separation between the subject and background.

The bright f/1.8 aperture allows photographers to:

• Create shallow depth of field
• Isolate subjects from busy backgrounds
• Capture portraits in available light
• Produce smooth, creamy bokeh
• Maintain faster shutter speeds in low light

The nine-blade circular aperture contributes to the lens's attractive out-of-focus rendering.

Autofocus
