Lightweight and Portable

This telephoto zoom lens packs a punch while remaining easy to carry around. The RF-S55-210mm f/5-7.1 IS STM is a fantastic choice for a second lens if you're looking for something with a greater range than a standard zoom.

It weighs only 270g and is approximately 92.9mm in length, making it easy to stow away in a bag or bring along on the go.

Why a Telephoto?

Reach further

Take stunning pictures of subjects that are too far away to approach.

Compression effect

Create the illusion that the foreground and background subjects are closer together than they actually are.


When the focal length is increased, both the background and the foreground are blurred more noticeably to give you beautiful bokeh.


Get Closer


Other than reaching further, this telephoto lens allows you to get up close too! At the maximum focal length, the RF-S55-210mm f/5-7.1 IS STM provides a magnification of up to 0.28x*, bringing your subject closer to you.

*minimum focusing distance of 0.73m


Image Stabilisation

The lens natively provides up to 4.5 stops of image stabilisation. With a compatible camera, image stabilisation can even go as high as 7.0 stops.

This allows you to shoot handheld in low light with shutter speeds slower than you usually could.

APS-C and Full-frame

The RF-S55-210mm f/5-7.1 IS STM may be used with both EOS R APS-C and EOS R full-frame* cameras. Hence, this lens is a great option for any existing EOS R system user who wants to expand their lens line-up to capture more variety of images.

The effective focal length ranges from 88mm to 336mm when used with both APS-C and full-frame cameras.

*Reduced megapixel count due to cropping by a factor of 1.6

Focus Breathing Correction


Focus breathing is a common problem that occurs as a result of changes to the lens's focusing distance when switching focus between subjects, which can be distracting during video recording. The RF-S55-210mm f/5-7.1 IS STM compensates for the change in field of view as the focus point is changed, resulting in seamless video recording.




Canon's unique leadscrew-type stepping motor (STM) keeps the autofocus (AF) running smoothly and quietly even when filming.

Dual Function Ring

Canon's signature knurled control ring functions as both a focus and exposure dial.

UD Lenses

This lens has two single Ultra-Low Dispersion (UD) lens elements with low refraction and low dispersion. This reduces axial and magnetic chromatic aberrations to improve image quality.
