Geotagging on K-70?

New K-70 user. I do not have the Pentax GPS Unit O-GPS1. When I transfer a photo to my phone after I arrive home, it shows where I took that photo. I tried to find a setting in the K-70 menu but did not see one. Happy to have that information, but wasn't expecting it without built-in GPS. If anyone can explain, I'd appreciate clearing up my confusion. Thanks

That's a feature of your phone, not your camera. The way it works is as follows: When you take a photo the time at which you took the photo is embedded in the EXIF info. As you walk around taking photos your phone's GPS tracks your location and saves it as a track log, which shows where you were at each point in time. The geotagging software on your phone then matches the time you took the photo (as recorded by your camera) with your location at that time (as recorded by your phone). This allows the software to create a geotag for each photo. So you see, you don't need any sort of geotagging functionality built into your camera. All you need is a really smart phone!

It will be fairly accurate as long as your camera's time is closely synced to your phone's time. You can do the same thing on a computer. I used to record a GPS track on a hiking app, then take the log file and match it up to the photos. Took a photo on both the phone and camera at the start (like of the trailhead sign) so I had GPS and time stamp references. Can't remember the software I used, but you could set it to adjust for the time difference between the phone and camera, then it would pull coordinates from the log file and insert them in the exif data on each photo. Got to be too much work, just bought the O-GPS1, much easier and allows astrotracer to function on the K70.

Edited to add: The O-GPS1 unit has really come down in price. I got a good used one off Ebay for $53.

Really? I will have to consider a search for one. I wanna expand my k-70 kit and in my country I really can’t find a used one.(yes, we are rare here) It still sells about 200-250€ new.

This is useful to know. Thank you. Since Covid I have been using the track function in my Android phone. Now it has another use.
