Features

Compact, Lightweight Fixed 50mm Focal Length Lens

Being bulky or inconvenient to carry is never a concern with the RF50mm F1.8 STM lens. Its compact size makes it appealing to bring on any trip or excursion and is quite handy to have around, too, with its 50mm fixed focal length letting you be creative with composition and because the 50mm focal length is similar to what the actual human eye sees, it provides a great representation to capture impressive portraits, landscapes, food photos and more.

Large F/1.8 Aperture for Low-Light Photography and Creative Background Blur

The f/1.8 aperture provides you with a number of benefits and options for your photography, including being able to shoot with faster shutter speeds in low light, helping to decrease the effects of camera shake for a more steady shot, reducing the amount of noise in your image, and the ability to beautifully blur the background or foreground depending on your creative taste.

A Stepping Motor (Gear-Type STM) Provides Smooth and Quiet Continuous AF During Video Recording, As Well As When Shooting Photos

The RF50mm F1.8 STM lens uses a gear-type stepping motor to provide smooth and quiet autofocus when shooting both still and video, so focusing appears seamless while following a subject with Servo AF, or Movie Servo AF. Focus racks will have clean transitions when repositioning to another subject, or when focusing from foreground to background.

Control Ring for Direct Setting Changes**

Standard on all RF lenses, the control ring on the lens barrel enables you to adjust numerous settings including shutter speed, aperture, exposure compensation and more. Located towards the front of the lens and effectively adding a third dial to the EOS R and EOS RP, and a fourth dial for EOS R5 and EOS R6 cameras, the control ring has a tactile, easily distinguished surface so you can grasp and make any setting changes quickly. This ring can also be easily switched to function as a focus ring with the focus/control switch located on the side of the lens, so you can adjust the focus to your desired preference.

Optimized Lens Placement and Coatings Help Deliver Outstanding Color Balance, While Minimizing Ghosting and Flare

Since you'll be carrying this lens with you quite often you'll want something that provides great results. The large diameter and short back focus inherent in all RF lenses helps with image quality while a carefully placed single PMo aspherical lens helps to reduce aberrations at the periphery of the image, with lens coatings further assisting by helping to reduce flaring and ghosting, so your images are clear, vivid and inspiring.

Circular 7-Blade Aperture Helps Deliver Beautiful, Soft Backgrounds

You'll have no problem getting that creative, fun and pleasant out-of-focus background blur we all love with the circular 7-blade aperture, so your subject stands out and the background provides a beautiful backdrop that's visually appealing in itself.

Minimum Focusing Distance of 0.98 Ft. and Maximum Magnification of 0.25x

Capture amazing shots wherever you are and whatever your subject, even at a close distance of 0.98 ft. at a maximum magnification of 0.25x, making this not just an ideal lens for everyday casual shooting but for more intricate shots like food, flowers and smaller subjects you really want to show off.

12-pin Communication System

Designed to quickly process data, the 12-pin communication system inherent in all RF lenses helps accelerate autofocusing and more, helping to simplify complex operations and provide a quick and reliable user experience.

Up To 7 Stops* Of Shake Correction with EOS R Series Cameras with In-Body Image Stabilizer

When combined with an EOS R Series camera with In-Body Image Stabilizer, you can experience the benefits of high-precision 5-axis image stabilization even without Optical Image Stabilization so you can capture amazingly clear and steady results while shooting handheld photos or videos, even in low-light situations like indoors or night scenes, without having to significantly increase the ISO or grab a tripod.

MTF Charts

A Modulation Transfer Function (MTF) chart measures a lens' expected optical performance at the center of the picture area and measures repeatedly along the diagonal line, further and further toward the corners of the image. The higher a curve is shown on the chart, the better the lens is performing in the area the chart is measuring. As a curve moves from left to right, it displays the lens' results from center towards the corners.
