I recently just purchased a cheap, made in China, Wireless remote for my Canon 5d Mk2 from Amazon. The Aputure Pro Coworker Wireless Remote Trigger is listed on Amazon for $142 but available now for $30. Not bad since the cost of one from Hong Kong on eBay is listed for nearly $80 + $15 s/h and a wait time of nearly 2weeks (coming from Hong Kong). I was able to purchase it for $40 with expedited shipping which is not too bad.
After opening the box I was surprised to find it to even come with batteries which is a plus. It seems very handy, before reading any instructions I was able to get it up and running and shooting from very far away. In the manual it mentions that the wireless remote has a range of 140 feet, which is not too bad for a $40 wireless remote. Another good thing about this is that if you do not want to use the wireless remote, you can you the receiver as a trigger without any use of batteries. It’s a pretty handy little gadget for your camera bag that doesn’t hurt your wallet too much. Though it doesn’t have any timed shutter release it is still a good wireless remote which you can use from about 140 feet away.
I will give it a proper test this weekend as I shoot my uncles wedding in which I am also a groomsman in so this will be handy as I walk down the isle.
