Nikon GP-1 Review

Nikon GP-1

November 1, 2010

The Nikon GP-1 is a GPS Unit that allows you to "geotag" your images. The information that can be added is latitude, longitude, altitude and time information.
I know a lot of nature and travel photographers have been waiting for a way to geotag their images in an easy way for quite some time. Used with Nikon View NX(2) and google maps, you can easily find the location of your latest shoot, and makes returning to the same spot, and or location easy.
The Nikon GP1 can be mounted to the hot-shoe on the camera or on the included camera strap adapter GP1-CL1.

Nikon GP-1 Connections
USB and wired remote(MC-DC2) connection.


  • Included cables, for once we don't need to buy additional cables for different cameras.
  • Size (the cables sort of ruins this, especially if you use the GP-1 in the hot shoe)
  • Sturdy build. Although made of plastic, it feels like it can take a beating.
  • Easy to use.


  • On cameras with the 10-pin remote, you need a new cable release (MC-DC2) if you are planning on using the GP1 unit and a cable release at the same time.
  • No on/off switch.
  • Altitude seems to be quite off sometimes.
  • Cables, I find the supplied cables to be way to long.

Easy to use, just slide it in the hot-shoe or slide it in the strap holder, connect it to your camera and you are ready to go. Geotagging can be really useful if you are scouting for locations, or need accurate references for you pictures. If some of your pictures don't get the geotag, it can easily be added to the picture in ViewNx2. This is just a copy paste operation.

The supplied cables are way...................... too long, and could have easily been half the length at least for the 10-pin cable for the D3. I'd like to see optional shorter cables for the Nikon GP-1. The unit itself is small and lightweight, no problems fitting it in a pocket and won't take up much space in your bag.

I recommend turning off: auto meter off in the camera menu to have a higher accuracy with the geotagging. This will drain more battery, but will give you less waiting time for satellite lock. Do note that if you forget to turn your camera off with the auto meter off, it will drain about 50% of the D3 battery in about 3 hours. You should also use it in the hot shoe of the camera to avoid errors, if you need accurate info on all your files.

A few questions I've seen that people want answers to:

  • Does it takes forever to start up? Sometimes, especially if it's been a long time since it was last used. In most cases startup is less then 40 seconds.
  • Does it drain the battery? Not a huge amount, unless you turn off "auto meter off". The GP-1 will use power even if the camera is turned off. According to Nikon t takes approximately 3 hours before the unit stops draining power from the camera.
  • Does it work indoors? rarely, the unit is clearly not designed to be used indoors.
  • What's the USB connection for? The USB connection allows a windows computer to acquire positioning information from the GPS Unit GP-1

Nikon GP-1 Glitch
#1 and #2 is shot from the exact same position. What seems to have happened is a glitch, and mostly happens when you use the camera strap holder for the GP1. I've seen this a few times. Shot #1 is pretty correct I must say. #3 altitude reference is sea level(negative value), even though I'm about 60m above it (info taken from picture #2)
