Image rotation on K5

Help please.
Ive just noticed that after taking a photo in portait format, if I orientate the K5 to portrait, the image doesn't automatically rotate as it does on the K7. I've set auto rotation to 'ON' but it makes no difference.
The status screen rotates but not the images.
Anybody else noticed this? Is this normal on the K5?

I've also updated the firmware to version 1.13.

Thanks for any help

Hi Michael,

C4 23 1 rotates the image so on playback it's the right way up.

Turning the camera afterwards does turn the info screen BUT not the playback images on the K5.

Oh! Strange Pentax have not carried that over from the K7, it was a nice feature.
If that's the case then at least the camera's ok.

Thanks wvbarnes for the reassurance.

By the way....updating the firmware has improved the autofocus considerably!
