Canon EOS R6 vs Panasonic Lumix DC-S1 — Which Is Better?

The Canon EOS R6 and the Panasonic Lumix DC-S1 are both full-frame mirrorless cameras, released in 2020 and 2019 respectively. That shared full-frame sensor format gives both the same framing and depth-of-field character from equivalent lenses. The R6 leans toward speed in a smaller body, while the S1 offers a higher-resolution sensor in a larger build.

The R6 measures 138 x 98 x 88 mm and weighs 680 g, against 149 x 110 x 97 mm and 899 g for the S1, a 219 g difference. That matters for travel and long handheld days, where the Canon keeps the overall kit smaller.

The Lumix DC-S1 is the stronger choice for heavy cropping and large prints, with 24.2 megapixels against 20.1 on the R6. That extra resolution leaves more room to reframe a distant wildlife shot in post while keeping detail. The R6 answers with speed: 20 fps continuous shooting versus 9 fps, plus 1053 autofocus points against 225, which suits fast action like sports or birds in flight.

Both cameras offer in-body stabilisation, a 1/8000 second maximum shutter and an electronic viewfinder, so handheld slow shutters and wide apertures in bright light are equally available. The S1's viewfinder resolves 5,760,000 dots against 3,690,000 on the R6, giving a sharper, more detailed eye-level view when composing fine scenes. The R6 offers a native ISO range reaching 102400, compared with 51200 on the S1.

Slow motion is where the R6 takes control, with a maximum video frame rate of 120 fps against 60 fps on the S1, and both cameras record 4K video. Filming a gymnast or a wave breaking at 120 fps gives far more room for dramatic slow-motion playback in the edit. Both record MP4, and the R6 adds a built-in interval timer for timelapse work, which the S1 does not offer.

The S1 gives you a larger, sharper rear screen for reviewing focus and detail on location: 3.2 inches and 2,100,000 dots against 3 inches and 1,620,000 dots on the R6. Both screens are touch-enabled and articulating, which makes waist-level and vertical framing practical on either body.

Weather sealing, Wi-Fi and Bluetooth appear on both, so transferring images in the field and shooting in damp conditions are covered either way. Neither body has GPS, and both rely on an external flash rather than a built-in unit.

Both cameras carry dual card slots with UHS-II SD support, so high-speed continuous bursts can be written without a bottleneck. The S1 adds an XQD slot, a useful second format for large video files or a separate backup card type.

Battery ratings are close, with the S1 rated at 380 shots against 360 for the R6. Both support USB charging, so topping up from a power bank between locations is straightforward on either camera.
