K30 Cable release

Can't seem to hold focus when using a cable release with my K30, just the slightest touch on the cable release button and the shutter activates immediately. Admittedly it is a cheap one off Ebay. Has anyone else experienced this problem with a Cable Release? Any thoughts would be very much appreciated.

My shutter release cable has a definite two stages when you push the button.

Check that the plug on yours has three sections separated by two bands.
This is what allows the half press for focus and full press for shutter.

If it has only two sections separated by one band then that cable does not have an 'AF at half press' feature.

If it looks right but does not behave that way then it is faulty.

Check The Plug!

Hello Hayzeedays, Welcome to the Forum!
Larry is exactly right, the better cable releases have a definite détent or half-stop for AF lock before shutter release. The OEM Pentax release ($40 USD, yikes!) has a really solid click-stop, the next best I've found is the 'Pixel' brand sold on eBay. Cheaper ones may or may not work as well. Both my Pentax brand and Pixel have the plug (or jack) in 3 sections, divided by 2 black bands, as described.

An immediate solution using your existing wired release is to remove AF from the shutter release, instead using the AF/AE-L button.
Menu/Rec.mode 4/Button Customization: Option Enable AF2 - Autofocus is performed only when the AF/AE-L button is pressed and not when the shutter release button is pressed halfway.

You would focus using the AF/AE-L button on the camera. Using AF.S, this will effectively lock focus at that point. Then use your wired shutter release to take the picture.
