Kr autofocus problem

I haven't used my Kr in a while (about a year) due to my disability but when I went to use it (tried all modes) the lenses aren't auto focusing so I was wondering if anyone can tell me what might be the problem and if it can be sorted?
Thanks

1. Recharge the battery

2. Take the lens off and clean the contacts on both camera and lens with a lint-free cloth

3. Pray

4. Make sure the camera isn't set to manual focus.

Had you set the camera to only focus with the back AF button? I've thought the same as you before now and that was the reason.

Ok , what happens when you press the AF button on the rear of the camera...ie not by shutter button half press ?

It will be in the settings. But what happens if you press the AF button on the back of the camera ?

Yes, if that focuses the camera the AF is working fine, it is just a setting. Worry about which setting later!

When pressing the AF it does the exact same the lens motor just seems to make the focus go in and out trying to focus but won't if you know what I mean.

Ah, I think we've all misunderstood and thought the AF didn't do anything. So it does, but doesn't select a focus point? Is that right?
