I know that the GP-E2 is available for the newer Canon bodies. I notice that there are a lot of third party options for Nikon bodies. Anyone know of inexpensive way to get gps tagging without the 250$ price tag? I have found solutions for nikon costing 40$ that looks very similar to what the gp-e2 achieves. I have tried EyeFi and I think it is a waste of time. (too small capacity, and it must be uploaded to eyefi and besides it not really GPS, it wont work where there aren't any hotspots). What are my options of i want GPS tagging in Exif, and lightroom comaptible?
