My cameras are able to take pictures before pressning the shutter, I have only used this on a few occasions to capture cannons shooting a salute.

If I remember correctly, you have to use a special setting and then half press. The camera start taking pictures at a fast pace without saving them. When the action takes place you press fully and you’ll have pictures from a few seconds back before you reacted.

It’s really cool and gives you a much bigger success rate. If his Sony camera have this feature, I don’t know.
