NEEWER JYC JY-710-C3 Wireless Timer Remote Control for Canon EOS 1Ds Mark 3 1D Mark 4

Just thrilled with this purchase.Fits a 5DMKIII - don't be an idiot like me - the square-ish connector goes onto the pins. Great for long exposure, easy set up, didn't have to read directions to figure out how to use. Excited to use this on my trip to Korea.

There should probably be a power button. There isn't so you have to take the batteries out when you are done using it. I have about 25k invested in lenses and bodies and surprised myself to not buy a name brand or heavily reviewed item, but for the price it was totally worth it compared to how often I use it. Great for a hobbyist, meh for a pro.

Bought this as a gift. My BF loves it, he sais it works perfectly on his Cannon camera.

when camera sleeps I have to unplug the trigger and plug it back in again to get it to work, other than that it works fine.

Using it with 20D canon. Works fine.

Works well and easy.
