GearScore™ Verdict — Which should you buy?

Travel & Landscape — OM-D E-M5 Mark II (2015): 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.

Casual & Travel — A5100 (2014): The A5100 is one of the smallest APS-C mirrorless cameras ever made. Its 24MP sensor, phase-detect AF, and selfie-friendly flip screen pack remarkable capability into a shirt-pocket-sized body. No EVF or hot shoe limits it for serious use, but as a compact travel camera or beginner's first mirrorless, it punches well above its price on the used market.
