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.
Full-Frame Value — Z5 II (2024): The most accessible full-frame mirrorless — dual card slots, weather sealing, and Nikon colour at a sensible price.
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.
