True, but just like doing it with manual focus, the key is to manage the angular velocity of the "fast thing" through the field of view. :-) That said, I'm perfectly happy with Pentax AF for motorsports except for one little thing that I can correct for. As I've discussed here before, including recently, it seems like when I'm panning, the AF is a couple of feet behind my eyes or the "lock time" hoses me or something. To get the cockpit at frame center to be the in focus part of the image, I have to set the AF point to the one on either side of center (depending on the direction of travel) and keep the camera's center AF point centered on the cockpit area of the car. Of course, this could also be more of an affect of the center of the car's turn not being the same point as my center of rotation as I pan the camera. Or it could be a bit of both ... or neither ... or something totally different. :-) > That doesn't mean there isn't room for improvement; I'm > really looking forward to the K10D with DA* SDM lenses. > But I miss a whole heck of a lot more shots by tripping > the shutter at the wrong time, or not quite getting all > the car in the frame, than I do to auto-focus failures. You and me both, not to mention panning at the wrong rate. I'm hoping that SR will help increase my "keep rate" by helping to eliminate any vertical shake I'm introducing as I pan. -- Thanks, DougF (KG4LMZ) -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
