That Duster is bad ***! What lens , f/stop and speed you using? My Grand Prix event is coming up and cant decide on bodies. My Fuji has a better lens but its old. My Pentax has a newer body with catch-in-focus, would be great to set it up on a turn and just have it click when a car comes into focus at about f/4

1/400 F/4@300MM
Body was my 1DX, which back then had some goofy focusing issue that Canon repaired, Lens was an Canon EF 300mm F/2.8L IS II USM.
The body would work flawlessly for thousands of shots...then out of the blue would simply stop focusing. If I flipped the mirror up, took one live view image then dropped the mirror back down it would start focusing again. Sometimes the problem would resurface almost immediately, sometimes it took several thousand shots.
