EOS R100vs Z6 IIIvs OM-1 II
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.
Hybrid Video & Action — Z6 III (2024): Partial-stacked FF sensor for near-zero blackout, 6K RAW video, and 60fps burst — Nikon's most capable hybrid.
Wildlife & Action — OM-1 II (2024): 120fps burst, 8-stop IBIS, and IP53 sealing — the most capable wildlife and action camera in the Micro Four Thirds world.
