Originally posted by RonHendriks1966 Well when AF is set to focus accuratesse (is that correct) then you only get a little less then 3 fps at max with moving objects. With framerate priority you get up to the 7 fps and not to many off them in focus.
I always use "Focus priority" rather than "FPS priority".
I've just had a look in Lightroom at sequences of aircraft in flight, looking at the time in the metadata. Within a minute or so of looking, I was able to find a sequence where there were 6 images (a Storch!) within the same second (10:16:08 on 1st September 2013; but this was one hour out because I hadn't taken account of summer time). Raw (DNG), no JPEGs, DA* 60-250mm f/4.
Whatever the theory, in practice I can sometimes get close to 7 fps in AF-C mode using "Focus priority" with my K-5IIs. Mostly they are in focus. But sometimes they are not, and often the fps is significantly less than this. I want better!
