Is the canon eos r6 mark ii worth buying used?
Yes, I'd buy the R6 Mark II used. It's a 24.2-megapixel full-frame body from 2022, and the R6 Mark III has since moved to 32.5MP and 7K video, so the Mark II is one generation back. That's the sweet spot my buying used guide is about: most of the camera for a fraction of the price.
Check the body's condition, and budget for a new genuine battery, because old batteries lose capacity. For an everyday kit, I'd pair it with the Canon RF 24-105mm f/4L IS USM and the Canon RF 70-200mm f/4L IS USM.
