The MZ/ZX cameras DO NOT have servo/continuous (same thing) AF capability. Predictave AF is not the same thing (which is all MZ/ZX cameras have). Aside from being able to keep a moving subject in focus, without firing the shutter, servo/continuous mode also changes the shutter release from focus priority (the camera has to think the subject is in focus before releasing the shutter) to release priority (the camera will fire the shutter when it is depressed all the way). It's the difference between getting an almost perfect focus picture at the right instant, and getting an almost perfect focus picture (moving subject with a MZ/ZX) after the "moment" has come and gone.
From: Chris Brogden In single shot mode, you're correct. In continuous shooting mode, my MZ-5n works a bit differently, though it may be a bit of a stretch to call it "servo AF." If I hold the shutter button down, the camera will focus continually while it shoots as fast as it can, up to 2fps. So after it takes a shot, I don't have to press the shutter button again to get it to focus. I just hold it down, and the camera keeps focusing. chris - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.
