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.
All-Round Full-Frame Photography — Z6 II (2020): The Z6 II is the Nikon most photographers should buy. It's balanced across every discipline — stills, video, autofocus, weather sealing — without overpaying for megapixels you don't need. The Z-mount glass is superb.
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.
