is it worth using the 240fps focusing? it degrades the live view quality, it disables the "enhanced" mode and it might even drain more power. But I'm sure we wouldn't hesitate to use it if the AF's visibly better. I was shooting the p25 1.4 today and I thought the 240fps might be better but no big difference I could find to prove my thought. Anybody has a more "modern" lens with 240fps enabled would share some experience?
