Pros & Cons Side by Side

Canon EOS R100 Mirrorless Camera

Most affordable Canon mirrorless with Dual Pixel CMOS AF — the best AF system at this price
24.1MP APS-C sensor delivers excellent results for social media and standard printing
Compact and lightweight — closest to phone-size of any reviewed interchangeable lens camera
4K video with Canon's colour science — the 'Canon look' valued by videographers
RF-S mount opens the full Canon RF lens ecosystem for future upgrades

No in-body stabilisation — Canon's R8 has the same lack but at a higher price tier
Limited buffer depth for burst shooting — not suitable for sports or fast action
4K has significant crop — full-width 4K not available at this price tier

OM System OM-D E-M10 Mark IV

5-axis in-body stabilisation at this price is exceptional — Olympus IBIS engineering heritage
Most compact interchangeable lens camera with IBIS available
Micro 4/3 system: smaller lenses enable genuinely pocketable total kit weight
4K video with 5-axis stabilisation for smooth handheld footage
Extensive Micro 4/3 lens ecosystem from OM System, Panasonic and Sigma

Micro 4/3 sensor smaller than APS-C — lower light performance than Sony or Fujifilm at equivalent ISO
Smaller sensor limits shallow depth of field for portrait work
OM System brand less recognised than Canon or Sony for those coming from phones
