I am not a professional and just wanted to have a remote release to etc. to focus on self-portraits from a distance and can trigger. And that's what can this remote release of Delamax. I use it for my Canon EOS 1000D and am very satisfied. Unpack, connect the camera ready. Nothing needs to be installed or cumbersome switched on the camera. In three steps, you can now use the camera. A brief press focuses the image, the full press of the shutter button pressed and a notch of the knob ensures a long exposure, very useful for example for continuous shooting. What do you want for more? The cable is 5 meters long whole, a real luxury, how even with expensive remote triggers has it not always. Moreover, through the cable connecting one escapes annoying disturbances as they often occur in radio triggers that then ruin the recording. The device adapts in focusing all camera settings, so that the self-timer mode can be activated, which in turn would make a timer at the remote release itself in my opinion unnecessarily. He sits comfortably in the hand, not too big and not too heavy, yet robust enough to even come outside safely used. The printed above connection is just that C6 for these Canon models. But there seems to be a version with the appropriate connections for other brands like Nikon, Sony, Minolta or Olympus. I do not know what should be the thing can do even more.
