The infrared remote release Mindax is very handy. (Men thumb size) He has a light weight of only 10 grams. The tactile feedback when pressing the shutter button is good to feel. Prior to use, the film should be removed from the battery receptacle. (Because of the remote shutter button is not often used, I lead the transparent plastic strips for use again.) To open the battery cover of the lithium battery CR 2025 I need two hands. (Somewhat strange) Inside was triggered using the remote control for a distance of 9.2 meters. When shooting with bulb Press 1x = trigger, again press stop recording. How long the battery will last (number of remote triggering) I have not tested.
