I'm not overly thrilled. In the item description, is that it would be consistent for Pentax, but I can not confirm. I have a Pentax K10D and can not work really useful with the remote trigger. Problem 1: The camera does not recognize that a flash is attached. That means I have to basically manually trigger and adjust the exposure by trial and error method, because the camera will expose more, because they think so, they photographed without flash. Problem 2: Even the release of the flash does not always work. Mostly it goes, then for some reason do not. This is really annoying, especially if you rely on it and then nothing goes. Makes a stop an unprofessional impression on photo shoots and the like.
