I bought the remote control to photograph plants pictures. Since the camera (Nex 5) hung on a tripod and was directed straight down, triggering on the device was a bit awkward. Thanks to the remote control you could lie down images, trigger, done. Since it has traded at over 1000 pictures, it was a huge relief. If you set the camera correctly, the trigger and the trigger delay is functioning properly. To the absolute top price !!!!
