Pentax CS-310 Cable switch Shutter Release – Accessory for Portable Devices

Attached to the PENTAX K-70 or KP’s microphone terminal, this one-metre-long cable switch helps prevent camera shake when using a macro or telephoto lens, since it allows the user to release the cameras shutter without touching it. When the user presses the CS-310s shutter release button lightly, the cameras exposure meter and autofocus system are activated. Pressing it all the way down releases the shutter. For extended exposures in the Bulb mode, the user can keep the shutter open by sliding the shutter release button to the HOLD position while depressing it.
