EOS R100vs Z30vs Ricoh GR III
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.
Travel & Everyday Video — Z30 (2022): Nikon's lightest Z-mount body — no fuss, excellent subject tracking, and a flip screen for creators.
Street Photography & Urban Reportage — Ricoh GR III (2019): The purest street photography compact — APS-C sensor, 28mm perspective, IBIS, and cult-favourite JPEG rendering in a shirt pocket.
