Any one use GPS data logger to take the location of the picture? I am looking to purchase one of them and your expert advice is highly appreciated.
I use myself Dawntech Pro L that works really nice on Nikon It uses battery of camera but draws really few power Log inside allows you to keep track of history When used in automatic mode, it gets on with camera and off with it, so you are sure to always get GPS data in your exif of pictures and no need of external softwares
