Originally posted by Col Personally I find the O-gps1 a real pain for day to day work. I bought it after my gps logger failed to hold a charge for longer than 3hours. Yes its convenient to have the data written direct to the image. But until they produce a hot shoe hub I'm stuck without geotagged images every time I'm using the ring flash.
I'm hoping that gps becomes inbuilt soon, or you could geotag the first shot and the camera could be told to use that info until a new reading in taken.
You can use both a flash and a O-GPS1 at the same time you just need more parts to connect it all together. This is because the system is a bus so if you have the connectors and cables it will work. You could still find it is a pain but that is a different problem then you can't use flash. Incidentally you could just take the first photo with the unit getting the GPS data and for the next photos use software like you do with a GPS logger and add the data to the rest of the photos.
Soon (2-4 years) this unit and just about any GPS unit is going to be obsolete as Galileo GPS and GPS III with the new channel will be coming on line. These new systems will allow these new units to get and keep a lock with much more covering the sky. They will also be more accurate. If the GPS is built into the camera the only way to get this would be a new camera. With a unit exterior to the camera (like the O-GPS1) you can just get a new GPS when they come out.
