Buy the R50 if you will shoot any video at all.Three of its advantages stack on video specifically. Uncropped 4K means your lens stays as wide as it is, which matters enormously if you ever hold the camera at arm’s length. The articulating screen means you can see yourself while you film. And Dual Pixel autofocus means the camera holds focus on a face as it moves, instead of hunting. On the R100, filming yourself in 4K means a cropped frame you cannot see, focused by a system that was not designed for it.
Buy the R50 if you are learning photography. The guided interface is not a gimmick: it shows you, in plain language and with a live preview, what moving each setting does. Combined with a touchscreen you can tap to place focus, it removes most of the friction between wanting a photograph and getting one. Our camera modes guide and how to use manual mode cover the same ground in text, but a camera that teaches while you hold it is better.
Buy the R100 only in one situation:you want daytime stills and interchangeable lenses for the absolute minimum, you will mostly use the viewfinder, and you are not going to film yourself. On those terms it is honest value — a 24.1-megapixel APS-C sensor and the RF mount for less than any other new mirrorless camera Canon makes. It is also the lightest of the two by a few grams, though not by enough to notice.
Autofocus is where the price difference actually lands
If you only compare one specification, compare this one. Canon’s Dual Pixel system uses the imaging sensor itself for phase-detection, which means it knows which direction to move the lens and how far. It locks on, it tracks eyes, and it stays locked. That is why the R50 is the camera we point first-time buyers at — focus is the thing beginners blame themselves for when it is really the camera.
The R100’s 4K mode falls back to contrast detection, which works by moving the lens and checking whether the image got sharper. It gets there, but it hunts, it is slower on moving subjects, and in video that hunting is visible in the footage. For static subjects in good light you will rarely notice; for a toddler, a pet or your own face, you will. If you want to understand what the camera is doing and why, autofocus modes explained and how to fix camera autofocus both help.
The fixed screen is a bigger limitation than it sounds
A screen that does not move rules out a whole set of shots: filming yourself, shooting over a crowd, shooting low to the ground, vlogging at arm’s length. It is also not a touchscreen, so you cannot tap to focus where you want — you drive the focus point with buttons, which is slower and more fiddly than it sounds when a moment is passing.
The R50’s fully articulating touchscreen flips out and around to face forward. For anybody who might one day point a camera at themselves — which is most people who buy a camera in 2026 — that single feature is worth most of the price gap on its own.
What they share, and what to buy next
Both cameras use the same RF mount, both are APS-C, and both have the same real limitation: Canon’s RF-S lens lineup for crop-sensor bodies is still thin compared with Sony’s E-mount. Neither has in-body stabilization, so handheld video from either needs a stabilized lens or a gimbal.
Whichever you buy, the kit zoom is the thing to upgrade first, not the body. The cheapest transformation available on Canon RF is the RF 50mm f/1.8 STM — see best prime lenses and camera or lens: what to upgrade. And if the R50 is close to your budget but you want faster burst shooting and a deeper grip for action, the step up is the R10 — compared head to head in R6 Mark II vs R10 and placed in context in best mirrorless cameras for beginners.
Both bodies are frequently bundled and discounted, so check the live prices in the table above before you decide. If the gap between them is small on the day you buy, there is no argument: take the R50.
