Here's a quick run through of what to expect from the Aputure Timer Remote when getting the Intervalometer ( Timelapse ) feature started. This timelapse remote is for the Canon 550D / T2i and will not work with the Canon 7D or 5D Mark II. The connection to the camera is similar to a mini stereo headphone jack. The other cameras use a different round connection type with several pins. This Timelapse is remote pretty straight forward once you do a quick run through on the user manual. There are much more features for this remote that I haven't dived into yet, but that will be posted up soon. There is no option to start and stop video (I get alot of those questions). It's a great little remote for the price of $22.00 dollars.
