O-GPS1 Pentax GPS Unit Review

A great tool for astrophotography! · 04-23-2012 · By PF Staff in Reviews

Today we're happy to announce our in-depth review of the Pentax O-GPS1 GPS accessory, a handy little device that adds geotagging, simple nagivation, and astrotracer capabilities to your camera.  In the review, we discuss the features of the device in detail, and show some sample star photos taken with the help of the GPS unit.  Overall, the O-GPS1 is a great performer, though it does have a few quirks, and at $199 ($249 MSRP), it is a little pricey.

The unit embeds the latitude, longitude and altitude (if it has that info with enough satellites available) in the exif.

Thanks for the review. I’m very interested in this unit and in particular the EXIF data that it embeds. Any chance of posting an image that includes all the EXIF data generated by the O-GPS1 unit.

@mrjamesabels, thanks for the tips. I'm just pointing out to people who think to do those shoot without merging frames. But guess that is not the main usage of the unit (take picture that contain stationary objects and stars)...

I'm happy with it mainly for Astro. Unfortunately, I live in NJ so a trip to Adirondacks for dark skys is in order. I like that the O-GPS is weather resistant. When I take out my cam and it starts to rain I can pop it on with out carrying the tiny piece of plastic. I have fully submerged it in a puddle by accident and let it dry out. Still works so I assume that it is better protected than I originally thought.

@LFLee Listen. On a tripod, manual focus on the foreground object, use bulb mode and light it up with an external flash or a flashlight. Keep camera in same position but manual focus on the stars using live view then use Astro feature to expose for the stars. Merge frames in photoshop erasing the blurry foreground to show the light painted focused foreground. Not to hard. No PS? try Layers plugin for LR3/4.

I have the O-GPS1 unit. It is great to geotag your photo, especially travel to remote area or while on a road trip. However, it is a bit pricey for this purpose. For star tracing, I found that shooting night sky photo will be more interesting if there is some stationary object in the frame, like tree, mountains, etc. In order to eliminate star trails, you will blur the stationary object.... so I don't know if this is real useful. Unless everything in your frame is just stars.... which sometime is not very interesting. I also feel $99-$120 is the reasonable price for this item, for what it did.

With the correct adaptors/cables/brackets’ all the flash options (including the onboard flash and P-TTL) can be used with the O-GPS1. I have used multiply different flash units and the onboard flash at the same time as I used the O-GPS1. In many ways the O-GPS1 is unique in all that it can do.

Very informative review. I was after some detailed insight into the unit and this review answered all my queries.

Good review; but if I might suggest some changes to the review.

Under the introduction section; could the Pentax K-01 be added to the cameras that can use this device? Also under specifications and pricing; supported cameras line - could it also be added there?

I've borrowed this device but have not yet purchased one. I would have really liked if the device would have a rechargeable option.
