Which should you buy?

High-Res Stills & Landscape — X-H2 (2022): Fujifilm's highest-resolution X-mount body — 40MP, 8K video, weather sealing, and 7-stop IBIS for serious photographers.
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.
