Our Verdict
Fujifilm X-T4
PENTAX K-3 Mark III
The PENTAX K-3 Mark III and the Fujifilm X-T4 are both premium APS-C cameras, but they use different technologies with different advantages and disadvantages. The PENTAX is a DSLR, so it's heavier and bulkier, but it has an optical viewfinder and longer battery life. The Fujifilm, on the other hand, is a mirrorless camera, allowing for a much more portable body. It also performs significantly better when it comes to video features and autofocus tracking.
