Use with D 600. A priori there is no indication that the PHOTTIX GEO ONE works with the Nikon D 600. Nonetheless used with it, it works fine, just use the appropriate cable. It is a pity that Nikon has not provided on the box D of the same front stacker 600 as the D 300 for example. The cable extends beyond the D 600 which is inconvenient to use, an angled connector partially solve the problem. Given PHOTTIX consumption, it is appropriate to provide one or more additional batteries. It is hoped autonomy 200 shots, depending on the configuration of the D 600 and its use, to check. My first tests show an accuracy of 5 to 15 m which is more than enough in my opinion for the use I make. Acquiring satellite is quite fast. Data visualization on a map with ViewNX2, GeoSetter eg. is fast, it is necessary to be connected to the web, as these software uses Google Maps. The PHOTTIX is complete, it comes with various cables, strap adapter, remote control, etc .. I was very skeptical about the usefulness of this accessory. I regret not having to buy earlier, he would have me very helpful during my travels. In conclusion PHOTTIX GEO ONE gives good results for a more reasonable price than the original Nikon, seeing reliability in time.
