Well, my first idea for day 1 was to shoot one of my kids practising her cartwheels, this would give me an opportunity to have a go with the af tracking. Yes, I know it's already been mentioned thousands of times by people that m43 isn't the best for af tracking but what do these people know, I'll come to that conclusion when I've made up my own damn mind, right? Er, as you can see from these images, (and these were at 1/8000), the focus is not the best at the beginning of the sequence, then has completely deteriorated by the end. It looks like the rest of the world is right. Not to say that there are other ways of capturing this scene, but af doesn't seem to be the best way. Photos binned.
