When Sony announced the A6500 APS-C mirrorless in 2016, I took it as the successor to the A6300, despite the fact that that camera had only launched about six months earlier. Why?

The new hybrid autofocus system has the same 425 phase-detection points as the A6300, but bumps the contrast-detection areas from 169 to 425. That's important, because contrast AF is what the A6400 (like most other cameras) uses for subject tracking.

An update to the latest image processor also boosts the features and image quality -- it usually does -- offering a higher maximum native sensitivity of ISO 32000 (both...
