GearScore™ Verdict — 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.
Video & Documentary — GH7 (2024): The GH7 is the GH series at its peak — phase-detect AF finally arrived, alongside 5.7K/60p open-gate, C4K/60p 10-bit 4:2:2, and ProRes RAW. A landmark video camera in the Micro Four Thirds format, and the most complete GH Panasonic has ever built.
