I grew up when cable releases were metal plungers and cost a couple of pounds. This High-tec device only does one more thing -it has an equivalent of partially depressing the shutter, just like you can on the camera. You need this if you are using autofocus, especially if you like the confirmation of a focus lock beep. If you own a good quality tripod for your Canon DSLR then this piece of kit is essential to prevent that little bit of camera movement you get when depressing the camera shutter.

At the end of the day it's just a cable-release. But it works fine, and if this is the one your camera needs (20D,30D 40D, and maybe 50D)then you may as well get one to stuff in your gadget bag, otherwise when you really need it...

must have for night or macro shots, next time I would have taken longer cable

This genuine Canon Remote Switch (otherwise known as an "electronic cable release") is an essential accessory for owners of Canon cameras equipped with the N3 remote coupling, enabling secure tripod-based photography for close-ups and long time exposures.

Although cheaper compatible releases are available on eBay, Amazon's low price for this original Canon product makes the nominal saving almost irrelevant if shopping elsewhere.

AS all photographers know this item is a must for long exposures,and a lot of tripod based photography
