Canon EOS R100 Review (2027)
In-depth review of the Canon EOS R100: 24.1MP sensor, Dual Pixel AF, the smallest EOS R body, and its fixed-screen and 4K compromises.
Canon EOS R100 with RF-S 18-45mm Kit (Black)
Canon's smallest and lightest EOS R body: 24.1MP, Dual Pixel AF with eye detection, and a built-in viewfinder.
Our verdict
The R100 is Canon's true entry ticket: the smallest and lightest EOS R body, a 24.1MP sensor, Dual Pixel autofocus with eye detection, and a real viewfinder, at the lowest price in the RF system. The compromises are equally real: a fixed screen and cropped, contrast-detect 4K. For stills-first beginners on a strict budget, the trade is correctly aimed.
What we like
- 24.1MP APS-C CMOS sensor with DIGIC 8 processing
- Dual Pixel CMOS AF with eye detection for easy first portraits
- Smallest and lightest EOS R body, with a 2.36M-dot electronic viewfinder built in
- Built-in flash plus Wi-Fi and Bluetooth in an entry-level kit
What to watch out for
- Fixed 3-inch screen with no tilt or vari-angle movement
- 4K24 video is cropped and uses contrast-detect autofocus
- Single SD slot and a 6.5 fps continuous ceiling
What owners report: Canon EOS R100 with RF-S 18-45mm Kit (Black)
Synthesized from recurring themes in long-term owner feedback.
Most praised
- The entry price into the RF mount includes a real viewfinder, which rivals at this tier often omit
- Eye detection autofocus makes a beginner's first portraits easy wins
- The compact body actually gets carried, which is the first camera lesson that matters
Common complaints
- The fixed screen frustrates vloggers and low-angle shooters used to tilting displays
- Cropped, contrast-detect 4K feels like a spec-sheet feature rather than a working video mode
- Menus and controls feel a generation behind the R50 for owners who compare them side by side
Who it is for
Budget-first beginners who shoot stills and want to learn on the RF mount without paying R50 money.
Stills first, by design
The 24.1MP APS-C sensor and Dual Pixel CMOS AF with eye detection handle the beginner workload, portraits, family events, and travel stills, with a keeper rate that flatters new technique. At 6.5 fps it tracks school sports adequately, and the built-in flash covers the indoor snapshots entry buyers actually take.
The viewfinder is the surprise
Entry bodies often delete the EVF to hit a price; Canon kept a 2.36M-dot finder in its smallest R body. Learning composition through a finder, with exposure preview, is worth more to a beginner's development than another video mode, and it makes bright-day shooting practical where a fixed rear screen washes out.
Video is the compromise
Full HD at 60 fps is clean and usable, but the headline 4K24 mode is cropped and focuses with contrast detection, which hunts in ways Dual Pixel stills shooters will not tolerate. Treat the R100 as a stills camera that can record serviceable HD video, and the spec sheet reads honestly.

Questions, answered
Does the EOS R100 have a touchscreen?
The 3-inch rear screen is fixed and is not a vari-angle touchscreen design like the R50's; framing for video and low angles is less flexible.
Is the R100 good for video?
Full HD recording is clean, but 4K is cropped and uses contrast-detect autofocus. Video-first beginners should step up to the R50.
Which lenses fit the R100?
It uses Canon's RF mount, so RF-S lenses are the native fit and full-frame RF lenses also mount, with the APS-C crop applied.
