EOS R100vs EOS R6 Mark IIvs Ricoh GR IIIx
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.
Portraits & Action — EOS R6 Mark II (2022): 40fps burst, 8-stop IBIS, and Canon's best-in-class Dual Pixel AF — exceptional for action, sports, and portrait work.
Street Portraits & Reportage — Ricoh GR IIIx (2021): APS-C in a shirt pocket with a 40mm perspective — the GR IIIx is the ideal street portrait compact for photographers who want a slightly tighter frame.
