I agree. I don't have trouble with the *ist D AF tracking racecars, either. I have the 100-300/4.5-5.6 also but haven't used it since I got the 200/2.8 and 300/4.5. I did use the 100-300 at the Petit le Mans with a ZX-6 several years ago, and don't remember any particular problems with the AF then, either. I haven't had a chance to take the K10D to the track yet. > leave choosing the autofocus point up to the camera. I don't because with the race cars, I often have to "manage" the DOF by intentionally biasing the focus point to compensate for the shutter's lock time. -- Thanks, DougF (KG4LMZ) -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
