anyways thanks for your help!!

Phew! Apparently the problem was the batteries, i have overcharged them and they were immeditely depeleted once i used them, i still was able to use the camera for almost half an hour and taking pictures on manual but apparently the AF needs a good battery supply

im going to get rid of this cheap charger and get a decent smart one!

Hi, i purchased the k100d five months ago, everthing was fine until this morning, the autofocus its not working at all, i searched every possible setting, everything seems fine and i can take pictures normally on manual focus.

On autofocus the camera makes the usual autofocus sounds but i never hear the focus beep. It keeps trying to focus but no no avail. Im getting quite worried and im wondering if the case to contact pentax support? anyone had the same prob
