Knowing that the k750i has autofocus, and knowing that autofocus requires a non-static lens, does it mean that the k750 really have a mechanical part that adjusts the lens' position?
To anyone who has opened their k750, is this the case?
Currently, i am not aware of any electronic method for accomplishing autofocus.

It sounds like somthing is happening in the phone (some mechanic sound(not from the loudspeaker)) and you can feel a slight vibration when it focus so yes i really think the lens moves inside the phone.

real mechanical autofocus!
thats great! se must have really made a miniature lens mechanism given that the phone is not really that thick.
btw, autofocus means that the phone emits something that gauges the distance between the camera and the target, have you guys noticed something like an IR emitter that is located near the lens?

maybe Sony is behind the make of the miniature lens mechanism, and ericsson sits on its behind all day and smoke cigars

that may be true. however i dont recall sony having a cybershot with this small form factor. the camera module of this phone is a lot smaller than those of dedicated digicam.

Autofocus does not require something emitted to guage distance. In fact, most autofocus systems use "contrast" detection rather than distance detection--they vary the length of focus to maximize the contrast between light and dark areas inside the focus area, the theory being that, the sharper the transition, the better the focus. So, if you're ever having trouble getting your autofocus to lock on, point the middle of the viewfinder at an "edge"--the side of someone's head, or their harline, or the edge of a building (if you're photographing the building), lock on focus with a half-press, and then recompose your shot and finish pressing the shutter button.

If you use the macro mode and focus - you can really hear the lens move.
