Autofocus (AF) underpins versatility and decisive shot capture, especially in dynamic conditions such as wildlife or sports. Comparing these two Canon compacts exposes rigorous differences in AF architecture reflecting their distinct target audiences.

Canon PowerShot SD3500 IS

This older model features a contrast-detection only AF system without face or eye detection and only supports single AF mode during live view. There are no selectable AF area modes, resulting in a simple central AF point and no continuous tracking mode. This AF approach is adequate for casual photography but below par for demanding or fast-moving subjects.

Canon PowerShot SX620 HS

The SX620 HS employs an enhanced contrast-detection AF system with sophisticated face detection and continuous AF tracking enabled. It supports a 9-point AF array with center weighting and multiple AF area modes, including tracking - a substantial improvement for accurately locking focus on moving subjects. Though lacking phase detection AF (typical for compact superzooms), this system achieves respectable performance in most shooting situations.

Its AF continuous shooting capability of 2.5 frames per second surpasses the SD3500 IS’s paltry 1 fps rate, crucial for capturing split-second wildlife or sports moments.
