Canon RF 135mm F1.8 L IS USM Lens

The Canon RF 135mm F1.8 L IS USM combines a flattering telephoto perspective, luminous f/1.8 aperture and professional L-series optics to produce portraits with extraordinary clarity and background separation.

Its built-in optical image stabilization and fast Nano USM autofocus expand its usefulness beyond portraiture, making it equally capable for weddings, indoor sports, concerts, stage performances and low-light events. For photographers who want distinctive subject isolation without moving to a much larger super-telephoto lens, the RF 135mm F1.8 L is an exceptional creative tool.

🧑‍🦰 Exceptional Portrait Perspective

The 135mm focal length creates a flattering, compressed perspective that is ideal for tightly framed portraits. It allows photographers to work from a comfortable distance while producing strong separation between the subject and background.

It is particularly effective for:

• Headshots

• Fashion and beauty

• Wedding portraits

• Senior portraits

• Environmental portraits

• Dance and theater

• Candid event photography

The longer focal length also makes it easier to simplify cluttered locations by narrowing the angle of view.

🌙 Bright F1.8 Maximum Aperture

The expansive f/1.8 aperture gathers substantial light, helping photographers use faster shutter speeds in dim environments.

It also creates a very shallow depth of field, allowing the subject to stand out against a smooth background. This makes the lens especially useful for portraits, concerts, indoor sports and evening events where both subject isolation and low-light performance are important.

Precise focusing is essential at f/1.8 because the zone of sharpness can be extremely narrow.

✨ Professional L-Series Optics

The optical design uses 17 elements arranged in 12 groups, including three Ultra-low Dispersion elements.

These UD elements help control chromatic aberration and color fringing around high-contrast edges. Canon’s Air Sphere and Super Spectra coatings reduce flare and ghosting, preserving contrast when bright lights or backlighting enter the frame.

The lens is engineered to provide excellent detail and clarity from the center toward the edges—even when used at its widest aperture.

🎨 Beautiful Background Rendering

A nine-blade circular aperture produces smooth out-of-focus highlights. Combined with the 135mm focal length and f/1.8 aperture, it creates pronounced separation and a three-dimensional appearance.

The lens can turn busy foliage, venue lighting and distant architecture into a soft backdrop that emphasizes the subject rather than competing with it.

🛡️ Optical Image Stabilization

The built-in Optical Image Stabilizer provides up to 5.5 stops of shake correction under Canon’s specified testing conditions.

When paired with a compatible EOS R camera featuring in-body image stabilization, coordinated control can provide up to 8 stops of correction. This is particularly beneficial because small movements become more noticeable at longer focal lengths.

Stabilization helps with stationary and slowly moving subjects, but fast action may still require a sufficiently high shutter speed.

⚡ Nano USM Autofocus

Canon’s Nano USM system delivers rapid, accurate autofocus for still photography while remaining smooth and quiet during video recording.

When paired with a compatible EOS R camera’s subject-detection system, the lens can maintain focus on eyes and faces during portraits, weddings, performances and action photography.

A focus-distance limiter allows photographers to reduce unnecessary focus searching when subjects remain beyond a specified distance.

🔍 Impressive Close-Focusing Ability

The RF 135mm F1.8 L focuses as close as approximately 2.3 feet and provides a maximum magnification of 0.26x.

This is unusually useful for a fast telephoto portrait lens and allows detailed photographs of:

• Wedding rings and floral arrangements

• Fashion accessories

• Food and table decorations

• Flowers and plants

• Small products

• Hands and facial details

While it is not a true macro lens, its close-up capability adds considerable versatility.

🎭 Excellent for Performances and Indoor Sports

The combination of telephoto reach, fast autofocus, stabilization and an f/1.8 aperture makes this lens particularly effective when working from the audience or sidelines.

It is well suited to:

• Theater productions

• Dance recitals

• Concerts

• Basketball and volleyball

• Gymnastics

• Ice skating

• Indoor ceremonies

• Low-light candid photography

The bright aperture helps maintain fast shutter speeds without requiring extremely high ISO settings.

🎥 Creative Video Performance

The 135mm focal length creates a compressed cinematic perspective for interviews, performances, detail shots and carefully composed portrait sequences.

Nano USM provides smooth focus transitions, while optical stabilization helps reduce visible camera shake. The lens is especially effective for controlled filmmaking where the shallow depth of field can be used deliberately.

🎛️ Customizable Lens Function Buttons

Two lens function buttons are positioned around the barrel for convenient access in horizontal or vertical orientation.

Depending on the connected camera, these buttons can be assigned to useful functions such as:

• Autofocus stop

• Eye detection

• Subject tracking

• Exposure settings

• Other compatible camera controls

The dedicated RF control ring can also be assigned to aperture, shutter speed, ISO or exposure compensation.

🌦️ Professional Construction

Weather-resistant sealing helps protect the lens against dust and moisture during demanding assignments.

A fluorine coating on the front element resists fingerprints and allows dust and water droplets to be removed more easily. As with other weather-resistant photographic equipment, the lens is not waterproof and should be protected during severe conditions.

🆚 RF 135mm F1.8 L vs RF 85mm F1.2 L

Choose the RF 85mm F1.2 L when working space is limited or the brightest possible aperture is the priority. Choose the RF 135mm F1.8 L for greater working distance, stronger compression, stabilization and tighter framing.

🆚 RF 135mm F1.8 L vs RF 70-200mm F2.8 L

Choose the 70-200mm for rapidly changing situations where zoom flexibility is essential. Choose the 135mm f/1.8 when low-light capability, subject isolation and a distinctive portrait look take priority.

🆚 RF 135mm F1.8 L vs RF 100mm F2.8 L Macro

The RF 100mm F2.8 L Macro provides 1.4x magnification and is the clear choice for extremely small subjects, commercial details and true macro photography.

The RF 135mm F1.8 L offers a much brighter aperture, longer working distance and stronger background separation. It is the better choice for portraits, performances and indoor action, while still offering useful close-focusing capability.
