Which should you buy?
Full-Frame Entry — EOS R8 (2023): Canon's most affordable full-frame mirrorless — 4K/60p 10-bit and class-leading Dual Pixel AF at an accessible entry price.
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.
Creative Filmmakers & Experimental Photographers — Sigma fp (2019): The smallest full-frame camera in the world — Cinema DNG RAW and L-mount flexibility in a pocket-sized body that rewards creative shooters.
