EOS M3vs GH7
GearScore™ Verdict — Which should you buy?
Casual & Everyday — EOS M3 (2015): The EOS M3 was a meaningful upgrade over the original EOS M — bringing 24MP, a tilting touchscreen, and improved Hybrid CMOS AF III. Video tops out at 1080p/30p and burst shooting is modest, but for stills photographers wanting affordable APS-C quality, the M3 is a competent used-market option.
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.
