Which should you buy?

Street, Documentary & Rangefinder Enthusiasts — Fujifilm X-Pro3 (2019): The most opinionated camera Fujifilm makes — a hidden screen and hybrid OVF enforce deliberate photography, rewarding photographers who slow down.

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.

Creative Filmmakers & Experimental Photographers — Sigma fp (2019): The smallest full-frame camera in the world — Cinema DNG RAW and L-mount flexibility in a pocket-sized body that rewards creative shooters.
