Use the shutter button on a Pentax K5, but realized that the plug not really fit into the socket on the camera. Have the right, however, only not observed, initially realized, however, that sometimes the trigger did not work properly. It turned out that the outer insulation of the plug was so thick and is seated on a ring on the camera. Had then the plug handle carved in gross motor way. Since then, he fit better and there is no more contact problems. However, what is still disturbs the locking of the push button. At full concentration on the camera, it may then happen but relatively easy to get the catch with activated when triggered simultaneously. One then wonders about the very long trip time, until you realize that the catch has been moved. So convinced is not really, but you can use it. (The infrared remote control is already on the wish list - then also eliminates the annoying cable clutter)
