Excerpt: I bought the GP-E2 used. It didn't have the two cords to connect to the camera . The major failure was the lack of the Map Utility disc. That made the device useless. So back it went. Would't have bought it if the web description had stated that the Map Utility wasn't present.
Excerpt: Just purchased the 70D with the GPS-E2. Works great without the need to use the cable to the USB port. The only disappointment is that you need to remove the GPS for the pop-up flash to pop-up.
Pros: Easy to use, Good battery life, lightweight/portable, Nice features/settings, Superior build quality
Excerpt: I use the GP-E2 with my new Canon 70D Camera. It can be shoe-mounted, placed in a AB-E1 Bracket attached to the camera (and connected with an interface cord which is provided with the GP-E2), or worn in a pouch on your belt (and connected with a longer interface cable also provided with the GP-E2). I don't use all the features. I am mostly interested in tagging my photos with GPS location data. In my limited experience with the unit, I find it to be quite accurate.
Pros: Easy To Use, Improves Functionality, Well Made, Works Well With GPS
Excerpt: The receiver looks like a small space starship once mounted on my Canon 5D Mark III. Works nicely and easily. Sometimes connecting to the GPS takes 2-3 minutes, but cannot indicate in which conditions it is much slower than the norm. Having pictures tagged with all coordinates is a very nice feature to have, primarily went in urban areas or in the wilderness. Actually, it is useful everywhere. Always travel with spare batteries just in case.
Pros: Easy to use, Good battery life, Nice features/settings, Quiet, Simple controls/menu, Solid operation
Excerpt: I highly useful product for travel photography, and features great integration with the 5D mark III - no external cables required. Very fast signal acquisition, and very accurate and reliable location tracking.A little on the pricey side, but significantly better than the similar offerings from Nikon and the multitude of no-name GPS products out there.
Pros: Easy To Use, Improves Functionality, Very Accurate, Well Made
Excerpt: I have used this product in Europe and in the USA and it tags the raw files perfectly. It is relatively light weight and small and picks up signals very well, even in remote locations. Nice integration with Lightroom and great battery life. I like that is uses a AA battery, which I can pick up anywhere. I just wish the camera had this unit built into it, rather than being an expensive add-on!
Pros: Easy Interface, Easy To Use, Lightweight, Reliable
Cons: Expensive, Should Be In Camera, Uses Flash Hot Shoe
Excerpt: Works as advertised.Seems to be accurate to within a few feet of my location and runs on only a single AA battery. It would have been nice if it were built in though. I'm not always willing to give up my hot shoe, which this unit requires and I've got enough gear to keep up with as it is.
