That was my impression when using the FG grip. There was a greater torque reaction when the lens was being focused. particularly with lithium AA's in the grip. This did, however, stop after a few months: the AF motor died. Lesson learned: If you want long lived, fast AF get a body with a big AF motor that takes "real" batteries.

Does that mean that an autofocus body with a AA grip might sometimes focus a bit more rapidly than the same body with CR2's ??? Fred - This message is from the Pentax-Discuss Mail List.
