I would like to start with wired shutter release product,the advantage is >you can be full-proof from 'camera-shake' caused "blurry image".
When your camera supports a remote cord or shutter release, this may be a wise investment if you often take digital photographs from a camera mounted to a tripod. By remotely causing a digital camera to take an exposure, you can eliminate any chance of "camera shake" due to pressing the digital camera's built-in shutter button. This may be useful in night time, fireworks, cityscape,panorama photography or commercial product photography.
Examples of appropriate blurry images by google search.(yes you may also need a sturdy tripod for long shutter time)
Another advantage of Aputure Dual Head Wired Shutter Release is
For DHC-2 model,for Canon,Samsung,Pentax and Contax,It is equivalent with Canon RS-60E3 AND RS-80N3 remote cord,this is the one cord which comes with two kinds of Plugs. For Nikon and Kodak user,please check here..
For example,your first DSLR was Canon 300D and two years later you upgrade to Canon 1Ds Mark III,and your second backup camera is Pentax *istDL,and if you are using our Aputure DHC-2,it means that on all the way,you don't need to buy three different Wired Shutter Release Switches,just one product can cover all your needs.
So,you can use Aputure Dual Head Wired Shutter Release,if you want to reduce expenses on different accessories,need to be ready regardless of camera requirements.
One more just small thing,it comes with hook and loop strap to prevent falling by hanging or fixing it on tripod.
