[QUOTE="Moab Man, post: 158414, member: 11881"] 95% in focus is great! There is no issue with the focus. You have to remember your taking pictures at a high rate of speed and the camera is adjusting constantly as the object moves. Throw in the fact auto-focus works off the contrast the camera can identify. If your focus dot falls into an all white or black field then the focus will be challenged. And while you may not be focusing on an area without contrast the moving vehicle will at times cause your focusing point to momentarily lack sharp focus when it does pass through a no contrast area and then quickly recover when contrast is there again. From everything you have posted you and the camera sound like you're doing great at a 95% success rate. Although I am a little confused on your two posts as to whether you're getting 50 out of 1000 (not so good) or 95% of a 1000 (outstanding). [/QUOTE]
