EOS R100vs Ricoh GR IIIxvs A7C 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.
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.
Full-Frame Hybrid — A7C II (2023): Full-frame AI autofocus in the most compact body available — the best camera under £1,500 for hybrid shooters.
