    Maybe a Hong Kong company make an Alternative D400 sooner than Nikon

    • 800mm f/2.8 DX VR

      Yeah! Great idea!

      • BonJonJovi

        Or just be happy with the camera that you have. Is your current camera limiting you or is it your skill?

  • Gorji

    Has anyone used these to see their reliability?

    • Gohf

      I owned one of their earlier models. It was a breeze to use and very reliable. I don’t know about that iphone option mentioned above – it seems like a ton more of a hassle to sync trips and snap photos etc just to get the location info added to the camera. I’d much rather have it stored at the time of the shot.

      • Gorji

        Thanks Gohf.

  • Spy Black

    Here’s a better, cheaper solution that works with ANY camera:

    • Mr. Mamiya

      The last time I tried an iPhone based geotagger, it drained my phone’s battery in less than an hour. Quite useless for a hike or city tour. Is this one better?

      • Spy Black

        The problem is the iPhone, piss-poor battery life. However if you shut most of the junk apps running in the background (facebook, etc.), you should get better battery life. I couldn’t tell you how well this app will fare, although the reviewer in the video used an iPhone, so it may fare better.

        • Neopulse

          Turning off whatsapp also helps greatly the battery.

        • Mr. Mamiya

          And Android phones have a much better battery life? This might not be valid today, but in the past I heard the opposite.

          The iPhone works well for me in everyday use, even without explicitely switching off apps in background. The battery is just drained quickly when the geotagging app continuously locates the iphone over GPS/WiFi/network/radio cell. This won’t disappear when switching off Facebook.

          • Spy Black

            Depends on the phone, but yes, Android phones have better battery life. Some are as bad as the iPhone, and some Motorola models may be worse. But make no mistake about it, the iPhone has piss-poor battery life. Every iPhone user I know brings their charger with them and immediately plugs it in whenever they can. The same goes for a friend with a Motorola Droid.

            My present LG Optimus V can run all day without a charge and with use of GPS, Wi-Fi, and web browsing. My old Samsung Intercept was the same way. So yes, there are Android phones that do have better battery life. That’s one advantage of Android phones, you have many choices to choose from. With Apple, only one.

            • Mr. Mamiya

              Ok, now we know that you don’t like the iPhone. (I can’t complain, the battery last more than one day with average usage including GPS, web browsing, email and even Facebook and WhatsApp.)

              But you didn’t fully answer my initial question: Is that app on an Android phone a useful geotagger?Can I record a full-day hike or city tour besides normal usage, without going out of battery power?

            • Spy Black

              As I said, with some Android phones, yes. However the other solutions I ran across actually seemed better than using a phone for geotagging.

        • Ryan

          This is a long standing rumor. Very few apps actually run in the background; those are just recently used apps that are there for quick recall.

          • Spy Black

            If so the iPhone really has piss-poor battery life.

    • neversink

      I like the ideas behind this app, but one question:
      What happens when you are out in the middle of nowhere and have no data connection? It seems like it could be nonfunctional then.
      Battery life on iPhone can be extended on the iPhone by turning off unnecessary apps (as you stated) and by dimming the illumination to 50%.

      • Spy Black

        One person on that site mentioned that the app looks for license verification when you start it, which is rather odd. I have emailed the publisher about this issue and I’m waiting for a reply. As long as the app will run, you’re fine. GPS data is grabbed by your phone’s GPS circuit, it’s independent of the data connection. It will grab that data as long as you have a clear up-link to satellites .

        • Anthony

          I used the free (ad supported) Tracks app ( on my iPhone for GPS logging. Works extremely well, and works (in my limited experience so far) just fine in the absence of a cell connection. The tracklog can be saved to a gpx file for import into Lightroom for very simple geotagging. But any use of GPS on the iPhone5 seems to really drain the battery, as mentioned above. However, I don’t do very long hikes, so not an issue for me (yet).

      • Spy Black

        I just discovered a few more options. You can use any GPS that continuously records .gpx data with Lightroom (and possibly Aperture) and Lightroom will Geotag the images.

        If you don’t have Lightroom, there is a free open source app that will do the same thing here:

        So, going off the beaten path, I would use a hiking GPS unit and then sync everything up. This would also save your phone’s battery life, some of which are quickly drained by use of GPS.

  • MyrddinWilt

    Meh, I like having GPS and WiFi on a camera. But it has to be built in or it just isn’t worth the hassle.

    Add a Pocket Wizard and you have three dongles hanging of your camera. None of which do anything that can’t be done better by adding a $5 chip to the basic camera.

    If the camera had built in WiFi we could have WiFi radio triggers for flash as well as for camera control and downloading pics. If the camera had bluetooth it could use the GPS on my phone.

    If they won’t add it to the camera body, at least add it to the grip. $300 for the grip is stupid enough. The fact that it does nothing but hold a battery even more stupid.

    While we are at it, why don’t they make a flash gun that takes the same lithium ion battery as the camera?

    • lorenzo

      The GPS should be in the camera body and switchable; don’t see why it is so difficult to do that… marketing? Do Canon have it?

    • SickofWhiners

      Wow ‘MyrddinWilt’, could you whine and complain anymore?

      How do you go through like like that? (That was a rhetorical question, no need to answer…)

      Anyway, thank NR, I just ordered this GPS, if it works as promised, it will fit a need perfectly. I didn’t like the Nikon model with my D800.

      • MyrddinWilt

        Usually only when I am paid by a manufacturer to do so. People pay me to whine to them about their product plans before they release. Helps avoid product blunders, some think.

    • jmj

      There is a reason why most of cameras do not have Wifi or GPS. It’s the full body metallic alloy which works as Faraday cage and block electromagnetic waves. Antennas for Wifi and GPS should be build outside of the alloy, which might also be challenging because metallic alloy close to antennas might work as reflector for waves. Canon 6D has build in Wifi and GPS, but it’s metallic alloy does not cover top parts (top is just plastic).

      • Calibrator

        Who downrated this post? Everything jmj wrote is accurate.

      • andre

        My old Nokia N8 has WiFi, GPS and G3 and has a complete alloy body….

        • jmj

          In N8, antenna seems to be in top and lower parts of the phone, so it’s not inside of the alloy and there is just minor parts of the alloy which would block electromagnetic waves. Besides, Nokia is a telecommunication company and have already lots of experts who can design antennas. On the contrary, Nikon camera and optics manufacturer.

      • MyrddinWilt

        It is not that difficult to add an antenna to a mostly metal body. Apple managed it after a few false starts. The MacBook Pro and MacBook Air have all aluminium bodies.

        If you look at the D300 / D800 bodies you will note that much of the magnesium frame is covered by rubber for grippiness and the entire top of the camera has a plastic cover. It would be pretty easy to put an antenna under that.

        The D800 is actually rated for the EyeFi card. Reception on the EyeFi card is fairly good. It is only the pathetic low speed chip and horrid software they use that makes the EyeFi unusable.

        If rumors are correct, future bodies will be carbon fiber and this will be a non-issue.

        • jmj

          Well I didn’t say it’s impossible. There are just those things which makes it difficult to design an antenna which works. I would say that those false starts would indicate that it’s not so trivial to add the antenna. Besides, in dpreview’s review of 6D, they say that Canon has specifically left the top part of metallic alloy open so that Wifi and GPS can work, so not sure that putting it to a plastic near alloy would work so easily.

          And in macbooks wifi is quite essential, so Apple has a reason to use efforts design working alloys and antennas such that wifi works. In pro cameras (e.g. D4), wifi and gps are not so necessary and I would say that sturdiness provided by full metallic alloy is important.

        • jmj

          And of course there is that other thing that this way Nikon can make extra money by selling additional GPS and Wifi units to customers who necessarily wants those.

    • danpe

      If we assume you’ve read what jmj wrote about metal and radio I’ll add some more. The grip is probably the worst place to place an antenna, you’re either covering the antenna with your hands or it points to the ground. My gps is from solmeta and it has a short cable, the gps sits on the strap just to avoid blocking the signals. With antenna inside you’d get even worse signal when adding a flash or something else in the hot shoe or when holding by the grip (as on 6D).

      As for lithium ion batteries the ones used in cameras probably can’t handle the current drain from a flash safely. I haven’t taken any Nikon el battery apart, but standard cells are rated below 4 C (complete discharge or charge in 15 minutes) and a flash can drain much quicker. In the R/C world there are lithium cells rated at 20 C or more, but those are different beasts and cost more.

    • Calibrator

      Meh, I like having a flash on a camera. But it has to be built in or it just isn’t worth the hassle.

      • MyrddinWilt

        A built in flash is a rather different issue. It isn’t the fact that the flash is built in that makes a built in flash a poor option. It is the constraints built in imposes. Built in flashes are poorly positioned relative to the lens and they are rather weaker than is desirable.

        • Calibrator

          > It is the constraints built in imposes.

          This is exactly what makes my comparison valid:
          A built-in GPS imposes several constraints:
          – The GPS would use the camera battery, which reduces the shot count per battery (separate trackloggers use their own batteries, the Solmeta Geotagger Pro)
          – Body construction would have to take the GPS antenna into account. See the other comments for more on that. It boils down to a compromise in construction, at least partially.
          – If you buy an expensive external GPS unit you can use it on another body without having to pay twice. This depends on model and make, of course, but you can often order a different cable for using it with a different camera model. Built-in GPS always comes with a cost so you pay twice with two bodies.
          – Speaking of which: Many people don’t need a GPS unit – but they pay for it if it’s built-in.

          Granted, my comparison was a bit cheeky as a built-in flash imposes more constraints but people still demand it for various reasons. How many people have you seen that demand a built-in flash for even the pro-body (as a flash commander or to at least brighten something up in broad daylight)? I see those regularly.

    • Pat Mann

      Not only does the Nikon GPS require a dongle, it blocks the 10-pin socket so you can’t use it for remote release. The fact that this GPS has a pass-through for the 10-pin connector is a big plus. Here’s hoping the future systems will handle all of this through wireless. I shoot a number of situations when I need to remote release an elevated camera while using off-camera flash, and would also like to view and control on a tablet and while incorporating GPS coordinates for the shot. Nikon makes this very hard and expensive on my D300s, requiring separate support to aim the flash commander and no remaining connection for the GPS after remote release is attached.

      Here’s hoping my next cameras, the D400 and D800es, have this better developed.

      And while we’re at it, why can’t we make a flash commander that works outdoors in daylight and uses the same standard rechargeable AA batteries as the flash guns, remote control, and camera battery pack?

  • Brian

    Amazon shows not available.

    • I think this is a new product and is not yet available in the US.

  • n11

    I still don’t understand the purpose of a GPS, what’s the point?

    • Sahaja

      For documentary photography it is very useful.

      • Swade

        So not all that useful to that many people.

        • Jan F. Rasmussen

          Useful to quite many – most nature photographers for instance

        • JonP

          If you don’t have a need for one fine but don’t think that a LOT of other photographers don’t. Don’t be such a spoiled POS.

          • Swade

            Spoiled because I think not that many people need to spend money on yet another piece of equipment? You clearly don’t understand what spoiled means. Brush up on your English. That still doesn’t tell me WHY they need to have GPS for their photos besides it being nice to have. People don’t know where they are when they shoot? Why does one *need* a GPS device?

            • peterw

              A lot of photographers don t really need a camera. they could draw the scene, or simply remember it.

              Spoil is the idea of present era. Some consider it joy.

              If I forgot to set on my GPS, I use google maps to tag my photo’s, very much easier and thus precise than using a topographic map.

              If I like to tag them of course. It has some use when making pictures of wilde, rare plants and sharing the data.

              Voices are coming up to track working people with GPS. To make certain wether they did their jobs.

              This thing looks great. Is it powered from the camera?

            • Spy Black

              I’m not sure why you’re getting such backlash for your question, but you’re correct, most people don’t need to geotag their images. Geotagging is primarily handy when you need to return to a site, possibly for a reshoot. There’s a few other good reasons, but they escape me now, but otherwise yes it’s a fad gadget. Here’s some basic info on it:

              There is a double-edge sword with geotagging, when someone can use the recorded info against you, as in a court of law.

            • Take a road trip some time and then document where you were when you took a particular shot. I’ve had situations where I was in a different state than I remembered. GPS gives me an accurate record. As valuable in its way as the rest of the EXIF data the camera captures.

    • I like it as I’m wandering around in the woods or strange city that I can geotag exactly where a photo is made, either for my viewers or so that I can find the spot again in better light.

    • Micah Goldstein

      Years ago, I shot a beautiful landscape with my D70. I’d like to go back and re-take the shot at higher resolution. Damned if I’ll ever find that spot again. GPS would have helped.

  • san

    I like how the D700 is shown all wet like that.

  • Geoff

    Why hang an additional device off the camera when you can carry a small portable GPS in your pocket or in your bag and download the .gpx files and automatically process all the image files during post processing.

    • Romain LAMARCHE

      Exactly what I do !

    • Greg

      As do I– I carry an Amod device, but I suspect technology has advanced. Anyone have recommendations?

    • Robert Ash

      Excellent idea. Any more detailed instructions? I’ve never heard of this approach and I’m having a little trouble visualizing how it would work but would love to try it.

    • htehte

      I use my Polar RC3GPS watch for this. This watch is normal size compared to other GPS watches. Is recharged form USB connection. Lasts 10-15 hours when GPS is on, else for weeks.

    • Spy Black

      How do you “automatically process all the image files during post processing”? What app do you use to do this?

      • Spy Black

        Never mind, figured it out. 😉

    • Calibrator

      Downside: You have to charge up yet another gadget.

    • Micah Goldstein

      …because this adds GPS info directly to your files with one less step than what you’re describing.

  • mikon

    What’s the difference between a “Hong Kong based company” and a “Chinese company”?

  • chittu

    How about using Trails app on iPhone, export tracks and sync on your computer?

  • Donna A.

    I have the Aokatec AK-G for my D5200. It looks smaller than the above unit and I only paid something like $70 for it (I think I got it from an Amazon seller). The first one was defective but the manufacturer had excellent customer service, as did the seller and the second one has worked like a charm. Others are noting that you can embed GPS coordinates with other devices like an iPhone. I don’t like going through that extra step and having one that links directly to the camera saves time and energy adding GPS coordinates. Others may have different needs/not care about extra steps, but this has worked great for me.

  • I bought one of the older version, it worked fine for a couple of months and then failed. Contacted the company, let them know what had happened. They immediately replied, sent me instructions on how to return the defective unit. Replacement unit was received by me in a couple of weeks. It stil works several years later.

  • Micah Goldstein

    Do these units tag with a compass direction as well?

  • grateful

    Awesome. Thanks for finding this.

  • Brian

    Received email from the company. They have no US distribution and suggested I order direct from them.

  • Paul

    I bought one, works perfectly well with my D700, doesn’t work with my D800e. will wait to see what they have to say about it 🙂

  • markmimage

    The ONLY reason why these things aren’t built into a DSLR is because Nikon are more interested in raping us of our hard earned $$$ in accessories. How is this not obvious, especially when a company like this can do a GPS unit for 1/2 the price!? Batteries, Battery grips(the MB-D12 is over $600), GPS($312), WiFi (the UT-1 is $1,299), cables, wireless shutter release is $75 – all specific to your camera, so when you have to upgrade to the next amazing camera they release WITHOUT GPS and WiFi and all the extras that should come with your camera, expect to fork out an extra 2k just on accessories. Ridiculous we have to go through this circus.

  • ThePhotographer

    Hi all

    I’ve tested the ECO Professional (Pro-F) on a NIKON D800 now, and I’m NOT impressed.

    Well…yes it works fine, WHEN it works!

    1. The device is attached direct to the 10 pole socket with a rubber fitting. When moving around it tends to fall out. The producer must know about this problem since they added a small wire, so you can tie the device to the camera.

    2. With no battery of it’s own, it rely on power from the camera. But each time it falls out it has to connect to satellites again, and this can take a lot of time. Right now it’s been searching for 12 minutes.

    I’m looking forward to hear from the producer in Hong Kong, but for now I would return the device and look for another device.

    I’ll keep you updated.

  • Robert Smith

    I had one and it worked great, very easy on the battery life of my D800. Unfortunately the connection is plagued by the weak attachment point of these attachment style devices. This was not a cheap accessory, I was not pleased that it broke. OK, i kept it on the camera all the time, i wish it had a different method of attaching to the camera. i will not be buying any device that attaches to the 10 pin connector, Very week. Mine had a metal treaded connector that broke the small, weak, somewhat brittle plastic tube barrel connector under it. Maybe it would be wise to only attach it when you need a position report in the meta data.

  • hatetoregister

    Although this discussion started a long time ago, I would just like to add something in case someone comes across this as I did. The reason that a photographer would want to geotag her/his photos is simple. If you are a travel photographer, you need to have the location data when you submit photos. It wouldn’t be great to submit a photo for a piece on Oslo, Norway only to discover that the picture was actually taken in Reykavik, Iceland. Geotagging helps you keep your locations straight. Also, if you do survey photographic work, construction scout work, scientific field work like archaeology, paleontology oil and gas exploration, census work, animal exploration, rain forest work, crime scene work or architectural work, you need accurate location metadata for your photos that geotagging provides. If you are an occasional shooter, studio shooter or a hobbyist, then geotagging doesn’t really matter as much, but if you create photos for public consumption AND you shoot a lot of pictures, then you need location data. I did a shoot for a piece on Iceland. I traveled the entire ring road and took thousands of pictures. I DID NOT have a gps unit because I had just purchased a Nikon D810 and my typical setup was Canon. I can’t tell you the headache I had identifying all of those photos. I used my phone camera to take pics alongside my actual camera so that I could use the geographic information from the phone to tell me where I took pics. However, I took thousands of pics, so you can imagine the problem there. The phone died in some places and the wasted time during post processing was ridiculous. Never again! I will use a dedicated GPS unit with the Nikon MC-35 cable for the D810 so that I don’t have that problem on my trips again. Anyway, for those of you who might be wondering why a photographer would need to geotag photos, no you have concrete reasons for that need.
