Every smartphone is a GPS device. Every smartphone is a camera. So the images we save are all geotagged; the location is saved as metadata as part of the image file.
You might think that for competitive reasons, camera manufacturers would put one of those cheap little GPS chips in their cameras to enable that $3000 full frame camera to geotag like a smartphone. You might think so, but you’d be wrong. Most of the high end, full frame cameras from Nikon, Sony, Canon and Leica depend on a smartphone connection to geotag images. Mostly you’ll find GPS chips in lower end compact cameras. Leica had GPS in their SL full frame mirrorless, but removed it in the just released SL2.
Why? As far as I can tell, GPS chips are just too power hungry to run continuously in cameras. Smartphones get GPS fixes at intervals plus can use cell tower info to figure out where they are. So it makes sense for camera manufacturers to rely on a smartphone app to pass a GPS location for geotagging. Plus geotagging has never been a feature of these cameras, so unless you look for it, it’s not missed. Probably wouldn’t be used by most users in fact.
Since my casual iPhone images are all geotagged, I’ve looked at a few approaches for geotagging images from my current group of cameras from Leica and Nikon. For now I’m making do with inconsistent apps and manual input. But it’s clear that Bluetooth Low Energy (BLE) connections between camera and phone has become the favored solution.
