Released in 2019, the a9 II represents the sports-and-action flagship generation just before Sony's global-shutter breakthrough in the a9 III — its 24.2-megapixel sensor is stacked for fast readout, meaningfully reducing rolling-shutter distortion compared to a conventional sensor, but still reads line by line rather than capturing every pixel simultaneously the way its successor does.

Frequently Asked Questions
Is the a9 II still capable for sports and action photography?
Yes — its stacked sensor still delivers genuinely fast, low-distortion readout and rapid continuous shooting, even without the a9 III's global shutter; it remains a capable secondhand option for photographers who don't need flash sync at every shutter speed or the very last word in rolling-shutter elimination.
