Which should you buy?

Compact Street & Travel Photography — X-E4 (2021): The X-E4 is for photographers who want the minimum camera that still delivers maximum image quality. If you love shooting from the rear screen and want the smallest possible X-mount body, this is your camera. If you need a viewfinder or IBIS, look at the X-S20 or X-T30 II.

Dslr Enthusiasts & Outdoor Photographers — Pentax K-3 Mark III (2021): The finest APS-C DSLR ever made — class-leading weather sealing, optical viewfinder, 5-axis IBIS, and extraordinary build for photographers committed to DSLR.

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.
