Hello There, I have the Pentax O-GPS logger first used on the K5, now I use it at the K5ii. It was important that I have a reliable system that my GPS enters data directly into the picture. As I develop my .raw files with Lightroom 4, I see immediately where each picture was taken. Because the K5 and K5ii also owns the "easy navigation", I can always adjust an image with orientation, etc.. The logger blocked unfortunately the hot shoe, but that unfortunately makes each manufacturer so that converts the system in this way and white. The logger has after turning quickly receive GPS, the camera menu can also be set, how long to search when the connection breaks off. If the camera is in standby is also the logger to standby, the "wake" the camera is also the logger turns on again completely, 2-3 sec. Later, the reception is back. Priced the part is of course very expensive, but it is useful for me and I use the logger whatsoever. Because he, as the camera also, splashproof is it can be used even in the rain. The AAA power source holds about 8-10 hours of continuous use. If the battery / battery low indicated by a flashing on logger. I would buy the logger again. My can look within seconds where that picture was taken that I like
