Read the General ComparisonGeneralThe Canon EOS R6 Mark II is the lighter body of this pair, released in 2022 against the Leica SL2-S from 2020. It measures 138.4 by 98.4 by 88.4 mm and weighs 588 g, against 146 by 107 by 83 mm and 931 g for the Leica, a 343 g difference for all-day carrying. Both are mirrorless cameras with full-frame CMOS sensors, so the same focal length frames the same view on either body. The lens systems differ: the Canon takes RF glass and the Leica takes L-mount lenses, so existing lenses will steer the shortlist. | ||

Read the Optics ComparisonOpticsFor birds in flight or court sports, the EOS R6 Mark II is the clearly stronger choice. It shoots at up to 40 frames per second against 20 on the SL2-S, and its autofocus offers 4897 positions versus 225, giving far more points to place on an erratic subject. The Leica answers for careful stills work. Its fastest shutter setting reaches 1/16000 second, twice as short as the Canon's 1/8000, keeping wide apertures usable in bright light. Its 5.76 million dot viewfinder out-resolves the Canon's 3.69 million dots. Resolution is effectively shared at 24 versus 24.6 megapixels, and both stabilise the sensor in-body. | ||

Read the Video ComparisonVideoBoth cameras record up to 4K video, and both support frame rates up to 60 fps, so typical 4K projects fit either body. Each also includes a built-in timelapse mode for interval shooting. The one editing difference is file format: the Canon records MPEG-4 or MOV, while the Leica records MPEG-4. Shooters whose workflow prefers MOV get that only on the EOS R6 Mark II. | ||

| Features | 72/100 | 87/100 |
Read the Features ComparisonFeaturesThe EOS R6 Mark II is the better camera for vlogging, overhead shots and self-framed recording, because it is the only one of the two with a flip-out screen. The SL2-S screen does not flip out, but it is larger at 3.2 inches versus 3, and its 2.1 million dots resolve more detail than the Canon's 1.62 million for reviewing focus. Several features are shared: touch screens, Wi-Fi and Bluetooth for transfer and remote control, plus weather sealing for outdoor work. Neither body has GPS built in, so location tagging needs an external solution on either camera. | ||

Read the Storage & battery ComparisonStorage and BatteryFor long sessions away from power, the SL2-S holds the rated endurance advantage: 510 shots against 360 for the EOS R6 Mark II. The Canon uses an LP-E6NH battery, the Leica a BP-SCL4. Storage is largely shared. Both bodies carry dual SD card slots and support USB charging, and the Canon's slots add UHS-II compatibility for fast card throughput during burst shooting. | ||

Verdict
Choose the Canon EOS R6 Mark II for action, wildlife or hybrid video work. Its 40 fps top burst rate, 4897-point autofocus array and flip-out screen make it the stronger tool for fast, mobile shooting.
Choose the Leica SL2-S if you shoot considered stills and already own, or intend to build, an L-mount kit. Its higher-resolution viewfinder, shorter 1/16000 second shutter, larger rear screen and stronger 510-shot battery rating suit deliberate work in bright light over long days.
