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.
Studio & Portrait Specialists — GFX 50S II (2021): Medium format quality at the most accessible price ever — 51MP detail and tonal richness no APS-C or full-frame body can replicate.
Adventure, Underwater & Outdoor Use — OM System TG-7 (2023): Waterproof to 15m, freezeproof and shockproof — the TG-7 is the most capable rugged compact for adventure and outdoor use.
