The OM-D E-M5 Mark II is 8 mm wider, 3 mm shorter, 15 mm slimmer and 82 g heavier than the EOS M50.
Drawn to scale from the makers' dimensions (W × H × D). Front shown, depth on the slanted edge.
EOS M50 — Casual & Vlogging: The EOS M50 is the most complete-feeling entry-level EF-M camera — built-in EVF, fully articulating screen, Dual Pixel AF, and a well-designed compact body. Its 4K video carries a significant crop and loses Dual Pixel AF, making 1080p the practical option — but for stills and casual video, it remains an excellent used-market buy.
OM-D E-M5 Mark II — Travel & Landscape: The E-M5 II was the benchmark weather-sealed travel camera of its generation. The 16MP sensor is modest by today's standards but excellent in practice, and the 5-axis IBIS is genuinely useful. Weather sealing, a flip screen, and a high-res composite mode make it a practical companion. A highly capable used-market buy for travel and outdoor photographers who don't need the latest resolution numbers.
