In the past 18 months, I have tried to understand the K-3's AF-C parameters, through specific testing, and in the field, with birds in flight, and some sports shooting. I don't feel I have mastered the various AF-C functions, it is still a work in progress. I have decided on a few things though; always use Expandable Area, burst mode and AF Hold for tracking.
Originally posted by Deedee There does seem to be something weird going on with AF-C. I will often see a dozen in focus shots, followed by two misses, then several more in-focus shots in a single burst. Really though, how many shots of a passing bird will I keep? Probably one or two.
My experience with shooting a hockey game was a shocker. I used AF Hold high, with 9-point expansion. Focus locked on my grandkid's jersey like a bulldog. I had almost 100% hit rate, on what is, IMO, the toughest sport of all to shoot (dim, coloured lighting, speeds faster than running, shooting through thick, scratched Plexiglas panels held in place by 3" vertical aluminum supports). Brutal!
