It has been a while since I’ve looked at GPS units for my Nikon DSLRs and yes it’s sad that in 2015 we still have to look at external solutions. However, that is the current state of affairs and the good news is that the prices have come down and the units continue to get better. Recently I was debating going with a NEW Nikon D750 vs a D810. When I was leaning strongly towards the D750 I tested my existing GPS unit (the one on my Nikon D600) and realized that since the GPS port was in a higher spot on the body that my Dawn di-GPS Eco model just wouldn’t work.
It’s a shame because I really like the flush to the body design of the di-GPS Eco models. I reached out to Dawn Tech to see if there was one on the horizon for the D750 and they informed me that they were working on something, but it wasn’t ready yet. In the mean time I got the UPDATED Mini3 MTK S5. I had worked with the older model in the past and this newer one now includes the “Last Position Memory” function, which is great for those times when you go inside and keep shooting. More importantly it has an even lower power consumption (19mA, less than 1/3 of the current consumption of Nikon’s own GP-1). While it doesn’t have the flush to the body design that I like so much in the di-GPS Eco, it’s very lightweight and can either sit in the hot shoe or attach to the camera strap.
I ultimately decided on and bought the Nikon D810. So this means that I get to use the Eco ProFessional M model. This one has the same “flush” design that I like and it even has the important pass through terminal port so that I can use my cable release or other accessories.
The Bottom Line
I love geotagging my photos as I take them. I use the Maps module in Lightroom quite a bit for my landscape and travel photos. It’s also easier to answer that “where did you take that shot” question as the galleries on my website also take advantage of this data allowing visitors to see exactly where each shot was taken. Sure there are many solutions and even iPhone apps like this one, but the most accurate and convenient way is to have the GPS data logged right into the metadata of each shot as you take them. While I applaud Nikon for having direct GPS support right in the menu of their DSLRs, it’s a shame that in 2015 we still have to buy “EXTERNAL” modules. As I’ve said many times I’d love to see this either built right in or at least built into an “optional” battery grip. Until that happens The GPS units from Dawn are your best bet.
