Pentax Cable Switch CS-310
Attached to the PENTAX K-70’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 camera’s shutter without touching it. When the user presses the CS-310’s shutter release button lightly, the camera’s 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.
