Which should you buy?
Sports & Photojournalism Professionals — Canon EOS R3 (2021): The pinnacle of Canon's mirrorless lineup for speed — Eye Control AF and 30fps burst in the most rugged body Canon has ever produced.
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.
High-Resolution Creative & Documentary Shooters — Sigma fp L (2021): 61MP and phase-detect AF in the world's smallest full-frame body — the fp L is the most capable iteration of Sigma's extraordinary compact.
