The Sigma CR-21 Cable Release Switch is a wired remote for the Sigma SD14, SD15 and SD1 Merrill Digital cameras. Use of this cable release reduces the risk of camera-shake, which can result in blurred images, and is especially useful when using the camera with the Mirror up and when using super-telephoto lenses.

Allows you to fire your shutter from the end of a wire! Even has button lock for T function!!
Easy to use: just pry off the release jack cover on the SD15 and plug it in. Be careful to keep the SD15 jack cover safe, because it is easily lost. This wired release lets me be behind the camera. If I understand correctly, the infrared remote release requires you to be in front of the camera, so I was not interested in it. I am giving it only 4 stars instead of 5 because I find it a little too easy to latch the button in the pressed position. You would use the latch feature when shooting bulb, because you have to keep the button pressed in to keep the shutter open.
