Somewhere in your manual for the KX there is a "catch in focus" instruction. It must be turned on in your menu option. Menu option 2 AF On your KX menu settings> Menu #2 >Mode >Set to AFS. Custom menu 4 option 22 Using aperture ring> set to 2 "Permitted". Custom menu 3 option 21 Catch-in Focus> set to 2 "ON". Base of your Super Takumar (manual focus lens) must make metal contact with lens mount (search for this on the forums if you need to). Turn camera on and set focal length of lens. Switch focus switch on front left of KX to AF. Press shutter and hold down all the way while you manually turn focus on camera. Shutter will fire when the center spot is in focus taking the photo. This is how it works on my KX with a manual lens as an option to using your eye to try and get it right. Helps for when you don't have the time to spend carefully focusing. Hope this helps some.
