OK, it doesn't come with a split-image screen or anything like that (although you may be able to fit one designed for a different camera), but on other Pentax AF cameras, the in-focus indicator of the AF system will work with manual focus lenses, too, and (even better), when AF is enabled, the shutter button won't actually fire the shutter unless (or until) the subject is in focus. So you may "auto-focus" a manual lens by keeping the button depressed, then *slowly* turning the focus ring, or moving the camera to/from the subject, or letting the subject move; the camera will fire at the point where focus is reached.
This mechanism is often referred to as "snap-in" or "trap" focus, and can be very useful indeed. I'm not sure you get it on other brands of cameras. Some people say it is not accurate enough to shoot wide-open with high-aperture lenses, but you should be quite all-right with your zooms. - Toralf -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
