Which should you buy?
Portraits & Action — EOS R6 Mark II (2022): 40fps burst, 8-stop IBIS, and Canon's best-in-class Dual Pixel AF — exceptional for action, sports, and portrait work.
Professional Sports & Wildlife — Nikon Z9 (2021): The Z9 redefined what professional mirrorless could be — no mechanical shutter, 45MP stacked BSI, and 8K RAW in the most rugged Z body.
Travel & Lightweight Outdoor Photography — Olympus OM-D E-M5 III (2019): The lightest weather-sealed MFT camera — compact, travel-friendly, and capable with 7.5-stop IBIS in a body that fits in a jacket pocket.
