How good is the O-GPS1 unit?
Jan 14, 2012

I really like having automatic geotagging for my pictures.

Does anyone have the O-GPS1 unit? Plugs into the hot shoe, carries its own seperate batteries.

How long does the battery last? How accurate is the positioning? It says it has a digital compass - is there some way to record the direction the picture was taken in in the EXIF data?

How long does it take to acquire a signal after turning it on? Does it tend to lose signal in areas with trees and such?

Also - there's one thing that isn't mentioned on the pentax page or the amazon page, but I have an issue of popular mechanics that says the unit actually figures out your position/direction for long night exposures to move the sensor with the rotation of the earth, so you can gather lots of light without having star trails. Awesome feature for astrophotography. Why isn't that mentioned on the promo materials for the unit though? Does it do this?
