The most notable difference is price. One of my main (if not only) issue with Nikon’s unit was it’s price. Listed at £95 on the Phottix UK site, it’s a fair bit cheaper than the Nikon version which comes in at slightly more than double that price. (I couldn’t find any North American pricing or availability – I’ll update the post once it is).
Like the GP-1, the Geo One comes with cables to connect it to a number of Nikon DSLR models including the D90 and D300 among others. It also has similar ports to the GP-1 except that the package also includes a wired remote shutter release which connects to the GPS module using a mini jack connection. A nice bonus that makes the price even more compelling since you have to purchase the Nikon cable separately.
So how does it perform? Pretty much exactly like the Nikon version. Very fast satellite acquisition time, similar build quality and seamless interaction with the camera. EXIF data was captured exactly like the GP-1 and I had no trouble uploading photos to Flickr with the geotags being picked up and mapped correctly:
It also comes with a similar plastic strap clip to allow you to move the module from the hot shoe if you need to use it with a flash. As the module has the same USB port as the GP-1, you can use it with your computer and even came with a mini cd with some navigation software but I haven’t tried since it won’t fit in my MacBook Pro’s dvd drive.
Overall, an impressive module, if not a near exact copy of the GP-1. Assuming North American pricing is consistant with the UK, it should prove to be a nice inexpensive alternative to the Nikon module and I’m sure they’ll sell a ton of them. A lot of people seem interested in my GP-1…until I tell them what it’s worth. Phottix just may have hit the sweet spot with it’s extras and lower cost.
