I can't get the shake reduction feature in my K-70. It was there a few days ago. It's 'greyed out' in the info button options and also in camera 4 menu options. I just can't get at it to turn on again! It's the same with any of the mode dial options.
Could it have been affected by using an old K mount lens from film camera days? After that I put on the 50mm pentax lens that I got with the camera, but still has the problem. Set to single shot, no time delay.
