The original EOS R6, released in 2020 alongside the higher-resolution R5, took a deliberately different position in Canon's RF-mount lineup: a comparatively modest 20.1-megapixel full-frame sensor prioritizing speed, low-light performance and video capability over maximum resolution, a formula Canon carried forward into the R6 Mark II two years later.

The original R6 topped out at 20 frames per second in its electronic shutter mode, meaningfully slower than the 40fps ceiling its Mark II successor introduced two years later — a real, measurable difference for photographers specifically chasing peak burst speed, even though the R6's core resolution, sensor size and general image quality remained close to its successor's own specifications and continue to hold up well on the secondhand market.
The original R6 also lacked the Mark II's Pre-Continuous shooting buffer, a feature Canon added specifically to the later generation to catch action just before the shutter is fully pressed.

Frequently Asked Questions
Does the original R6 handle astro work as well as the R6 Mark II?
Very similarly — both share close pixel pitches on the same full-frame sensor size, so their maximum astro shutter speeds under the NPF rule land close together at a matched focal length and lens, with the Mark II's real advantage showing up mainly in autofocus and burst speed rather than star-trailing math.
