GearScore™ Verdict — Which should you buy?

Landscape & Outdoor — KF (2022): The Pentax KF is a rare thing — a weather-sealed DSLR with in-body stabilisation and an articulating screen at an accessible price. Video is modest at 1080p/60p, but for outdoor and landscape photographers who prefer optical viewfinders and want real weather sealing, the KF delivers in a format that is increasingly hard to find.

Studio, Tripod Landscape & Camera History — A7R (2013): The world's first 36MP full-frame mirrorless — a landmark camera that launched the A7R series, despite contrast-detect AF and significant shutter shock limitations.

↓ Full specifications below

KF (2022)

  • Outdoor and landscape photographers who want weather sealing at an accessible price
  • DSLR users who want IBIS and an articulating screen without switching systems
  • Pentax K-mount lens collectors who want a modern body for their glass
  • Photographers who prefer the natural feel of an optical viewfinder

A7R (2013)

  • Collectors and photographers interested in the camera that started the A7R lineage
  • Studio photographers who work on a tripod and can manage contrast-detect AF
  • Landscape photographers who prioritise resolution over autofocus performance
  • Sony FE system users who want a historical body at a very low used price

Quick take: The a7r has the highest resolution at 36mp; the a7r is the most affordable; only the kf is weather sealed. Scroll down for the full spec breakdown.
