Hi. I was wondering if anyone of you has Sony's GPS-CS1. If so, please tell me if I can use it to add locations to photos taken with my D80. I saw on the official Sony's website that it is compatibile with almost all Sony's cameras, but there was not even one from different company (like Nikon). I know that it uses some kind of software to add location to EXIF of your RAW/JPEG and that I must have my DSLR and GPS-CS1 synchronized to be acurate. Please tell me if it will work or not or maybe suggest some other equipment (close to this price).
