What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Canon EOS R6 Mark II
Both whitelisted hands-on testers (TechRadar, Tom's Guide) rate the R6 Mark II a top-tier hybrid: excellent deep-learned subject/eye-tracking autofocus, clean high-ISO images and 40fps electronic-shutter bursts with a deep buffer. Both flag its high price and modest 24MP resolution. They split on stabilization: Tom's Guide reports the full 8 stops and lists it as a pro, whereas TechRadar measured only ~4 usable stops at 105mm and found the IBIS unconvincing, especially for video. (2 sourced reviews, 2 lab-tested.)
Praised: Excellent deep-learned autofocus and subject/eye tracking; Clean, low-noise image quality at very high ISO; Fast 40fps electronic-shutter burst with deep buffer.
Flagged: Expensive relative to rivals (Sony A7 IV, Lumix S5 II, Nikon Z6 II); Modest 24MP resolution, unremarkable for a full-frame camera; IBIS falls short of the claimed 8 stops and struggles with video camera movement.
