EOS R100vs Lumix S5vs OM-D E-M10 IV
Which should you buy?
First Camera / Beginner Photography — EOS R100 (2023): The R100 does the basics well at the lowest possible price point. Its main value is as a gateway into the Canon RF ecosystem — the lenses you buy now will work on any Canon body you upgrade to later. Modest ambitions, reliably met.
Professional Video & Hybrid Shooting — Lumix S5 (2020): The S5 is an outstanding video camera that also takes excellent stills. 10-bit 4K/60p, dual native ISO and 6.5-stop IBIS in a weather-sealed body is a compelling package. The contrast-detect AF is its main weakness vs Sony and Canon — but for controlled shooting it doesn't hold it back.
Travel & Everyday — OM-D E-M10 IV (2020): Compact Micro Four Thirds body with built-in IBIS — ideal for travellers who want stability without bulk.
