I bought it for my Canon EOS 1100D. The wired remote control does what you ask him, namely trigger without blur risk due to camera movement, very useful when using a tripod. A half press of the button brings the focus, full press releases the shutter. There is also the option to lock the shutter for long exposures. The wire could have been a bit longer but it is not annoying. Although seen from Canon, the opportunity to wrap the wire in notches and push the jack into a hole for storage. An original accessory Canon, and for a very affordable price at Amazon. Definitely recommended.
