EOS R100vs Z5 IIvs 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.
Full-Frame Value — Z5 II (2024): The most accessible full-frame mirrorless — dual card slots, weather sealing, and Nikon colour at a sensible price.
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.
