Pixel TW-282 wireless remote & Time Lapse
I have one and it works well. The only thing is the transmitter turns on very easily in a bag so I take them out during transport. You can also take the batteries out once your time lapse is started as the information is in the receiver. I wish the transmitter would be smaller and use a single lithium battery instead of two AAAs.
Make sure you have the right cable for your camera.
