Which should you buy?
Compact Street & Travel Photography — X-E4 (2021): The X-E4 is for photographers who want the minimum camera that still delivers maximum image quality. If you love shooting from the rear screen and want the smallest possible X-mount body, this is your camera. If you need a viewfinder or IBIS, look at the X-S20 or X-T30 II.
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.
