Which should you buy?

Sports, Wildlife & Dslr Enthusiasts — Canon EOS 90D (2019): The best APS-C DSLR Canon ever made — 32MP, 10fps, weather sealing, and an optical viewfinder experience no mirrorless can replicate.

Landscape & Studio / High-Resolution — Z7 II (2020): The Z7 II is a landscape and studio camera first, everything else second. 45.7MP with weather sealing and dual card slots is a compelling package. If you need resolution, it delivers. If you don't, the Z6 II is the smarter buy.

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.
