Cameras by autofocus
Bodies grouped by how they focus. Phase detection reads focus direction in one step. Hybrid pairs on-sensor phase with contrast. Depth-from-Defocus is Panasonic's contrast variant. Contrast-only is accurate but slower. Manual-focus rangefinders sit out since they have no AF. 229 bodies across 25 AF systems.
Autofocus over time
Each dot is a camera. Older and slower sit lower-left, newer and faster climb to the upper-right. Click a dot to open that camera.
How the height works: it's a rough capability score, not a measured benchmark. Each camera starts from its AF type and rises with release year, since newer processors and subject detection sharpen every system. Phase-detect DSLRs lock fast but sit below modern mirrorless because they don't track subjects across the frame. Contrast and Depth-from-Defocus stay near the floor. The chart shows milestone bodies plus every tracked camera released after 2020. Smartphones are left out.
Phase Detection
51 bodies · 6 systemsDedicated phase modules (DSLRs, Pentax) and on-sensor phase like Canon Dual Pixel. Reads focus direction in one step, so it locks fast and tracks well.

28 bodies · 1 systemPanasonic's contrast variant. It uses lens profiles to estimate distance, which sped contrast AF up but still hunts in video. Panasonic has since moved most bodies to phase.

78 bodies · 6 systemsContrast-only. Accurate when it locks, slower to get there, prone to hunting. Common on older mirrorless and most fixed-lens compacts.

3 bodiesAF groupings are hand-maintained. Interchangeable-lens bodies are reliable. Some older compacts are best-effort, and a few Panasonic bodies near the 2014 Depth-from-Defocus rollout are judgment calls.
