A new integrated unit.

I have had great success with the Aoka GPS receivers attached to my two Nikons – the D2X and D700. You can read all about the technology here, where you will see that a separate data logger must be used. This goes in your pocket and receives GPS data from the satellite and passes it to the device on the camera’s body. The logger has a small rechargeable battery which can be recharged from any USB socket on your computer.

The new receiver integrates the data logger and receiver which I use. It’s a little wider but has the advantage that it’s impossible to forget to take the logger along with you, something I have managed once or twice. The drawback is that it drains more power from the camera’s battery as there is no separate logger battery to recharge. While I have not used it, the price is attractive. eBay asks $80, Amazon has it for more. One Amazon review has some useful battery drain metrics.

The device (model AK-G1) fits the Nikon D4/3/2 in all their iterations, D800/800E, D200/300/300s, D700 and Fujifilm S5Pro. There are other models to fit the Nikon D3100, D5000, D5100, D3200, D600 (model AK-G2), and the AK-G7 for the Nikon D7000, both costing $80 on eBay. The AK-G9 for the Nikon D90 has no integrated data logger ($40 – eBay) so a separate logger would have to be used.

The only failures I have had with mine result from ‘canyons’ in the city shading the satellite or not giving the device the 2-3 seconds to wake from sleep after a period of inactivity. I have also found that the older D2X is far faster at re-displaying the ‘GPS’ flag on the top LCD display than is the D700. So much for progress. The new device looks like a better mousetrap, especially as my separate logger can only support one camera at a time. Switch the D2X and the D700 on simultaneously and the D2X grabs and hogs the signal every time. The one logger cannot simultaneously drive two camera receivers.

Here’s the device on a Nikon DSLR – stock photo from the maker; I’m guessing it’s a D300:

As a friend of the blog and GPS expert points out, as GPS technology improves the advantage of these devices is that they can be inexpensively upgraded rather than having to buy a new camera body.

For comparison, here’s the earlier unit attached to the D2X, along with the small, separate data logger.

I cannot find inexpensive aftermarket devices for Canon DSLRs. The factory units run $195 for a Nikon shoe-mounted unit with a clunky cord connection to the socket and $250-279 for the various Canon units. Both seem ridiculously over-priced to me.
