Canon’s first ultra-wide-angle, fixed focal length RF lens.
A fixed ultra-wide angle lens changes how you see your image before you even press the shutter button. Your enhanced perspective and expansive views create a unique and engaging look of each photo. Whether you are capturing an awe-inspiring starscape, portraits with fun and unique distortion or simply a group selfie while on vacation, the combination of the open f/2.8 lens and ultra wide-angle 16mm field of view makes this a light weight and versatile lens to pack anywhere you go.
High image quality and bright, fixed f/2.8 maximum aperture.
A bright f/2.8 lens combined with the full-frame sensor of each EOS R series digital camera allows for fast shutter speeds in low light with less noise and the ability to beautifully blur the background in close-up shooting or video recording.
Stepping motor (gear-type STM) that provides smooth and quiet continuous AF
Using a stepping motor in the RF16mm F2.8 STM lens aids in natural focus while following a subject using Servo AF in still photography, or clean transitions when repositioning to another subject with Movie Servo AF in video applications. Canon’s STM focus motors are especially renowned for their smoothness in focus changes during live video recording, as well as brisk AF during still-image shooting.
Supremely lightweight and compact, for an ultra-wide lens for full-frame cameras.
The compact size and light weight of the lens makes it an ideal companion on long hikes and excursions. It is also handy for a day out in the city and when you want to be creative with multiple prime lenses.
Minimum focusing distance of 5.11 inches and maximum magnification of 0.26x.
Getting close to your subject with the RF16mm F2.8 STM lens means purposefully distorting your subject, creating an enjoyable new look while also keeping more of the background in frame for visual interest.
Control/Focusing Ring can directly adjust numerous settings.
The RF16mm F2.8 STM lens incorporates a control/focus ring on the lens barrel. As a Control Ring, it can directly adjust numerous settings including shutter speed, aperture, exposure compensation and more. Located towards the end of the lens, the control/focus ring has a tactile, easily distinguished surface and provides tangible feedback for confident use while looking through the viewfinder.
Circular 7-blade aperture helps deliver beautiful, soft backgrounds.
You'll have no problem when shooting close-up images in getting that creative, fun and pleasantly smooth out-of-focus background blur we all love with the circular 7-blade aperture. Subjects will stand out, and the background provides a beautiful backdrop that's visually appealing.
