Canon EOS M50 Mark II vs Canon EOS R100 — Which Is Better?

The Canon EOS M50 Mark II and the Canon EOS R100 are APS-C mirrorless cameras with the same 24 megapixel resolution, so crops and large prints draw on the same pixel count. The M50 Mark II, announced in 2020, takes EF-M lenses, while the R100, from 2023, takes Canon RF, and lenses do not cross between the two mounts.

The R100 is the lighter body at 356 g against 387 g, and measures 116 x 86 x 69 mm against 116 x 88 x 59 mm.

The M50 Mark II is the stronger pick for action, shooting at up to 10 frames per second against 6.5 on the R100, which helps when a runner or a pet crosses the frame mid-stride. The R100 answers with far denser autofocus coverage, 3975 selectable positions against 143, so you have many more spots for an off-centre subject.

Several core specifications match. Both share the Digic 8 processor, a 1/4000 second shutter ceiling, and a 2,360,000-dot electronic viewfinder. Neither body offers in-body stabilisation, so dim handheld work relies on the lens or a faster shutter. One difference favours the M50 Mark II: its ISO ceiling reaches 25600 native against 12800, with expansion to 51200 against 25600.

For slowing fast motion, the M50 Mark II gives more headroom, with a maximum frame rate of 120 frames per second against 100 on the R100. Both cap at 4K and include a built-in timelapse mode for condensing a sunset or a building project into seconds.

One editing convenience differs. The R100 records in MPEG-4, MOV and H.264, giving more format options when importing clips, while the M50 Mark II records in MPEG-4 alone.

The M50 Mark II is the easier camera to operate quickly, because its 3-inch screen responds to touch for setting focus points and tapping through menus, while the R100 relies on buttons and dials alone. Both screens articulate for waist-level or selfie framing, and both show the same 1,040,000-dot detail.

Both cameras include Wi-Fi and Bluetooth for transferring images to a phone. Each also has a built-in flash and supports an external flash, and neither offers GPS tagging or weather sealing.

The R100 carries the longer rated battery life, at 370 shots against 305 for the M50 Mark II, a 21.3 percent higher rating. They take different batteries, LP-E17 and LP-E12, so a spare for one will not power the other.

Both write to a single SD card slot. Both take SD, SDHC and SDXC cards, and the M50 Mark II's slot also supports UHS-I, so a fast card can clear a long burst more quickly.
