O-GPS1 GPS Module is rated 4.4 out of 5 by 20.
Rated 4 out of 5 by from Very useful accessory I have it attached to a K5 and have just returned from an extensive trip in the rural areas of Australia. It worked extremely well and was most useful in providing me data as to where my photographs were taken. I found it very easy to set up and calibrate and worked every time as long as you remember to hit the ok button at the end of the calibration. I had it turned on most of the time over a fortnight so i used about 3 batteries. It pays to carry spares with you (AAA). If you have been under cover (in a building or dense overhead cover) for a period give it a few seconds to get a reading once you come out. Does not require recalibration unless you have removed it from the camera or have had to change the battery.

Rated 3 out of 5 by from Does geotagging with Picasa well I bought this to have automatic geotagging in picasa, and this module works well for that purpose. It's well built, although I wish the K5 had a GPS built into it, since the module is fairly bulky sitting on top of the camera. I never use it for its astrotracing ability, and probably never will. For geotagging only, its a pricy accessory - but I'm sure it will pay for itself a year from now when I can go back and look where EVERY photo I've ever taken was from. So although Geosetter and an old GPS is a lower cost solution, it's a complicated one I rarely bothered to set up. The O-GPS1 module works for my purposes.

Rated 5 out of 5 by from Phenomenal results for AstroTracer, Astrophotography Purchased this product to facilitate the Astrotracer functionality on my Pentax K-50 camera. The GPS module allows for the accurate enough positioning that the Shake Reduction feature in the camera is used as a method for pinpoint stars during long term bulb photography. Normally to have no star trails, one has to purchase or make a barn-door mount that tracks the camera to the celestial motion. With the GPS module and the Astrotracer feature in the Pentax camera, I was able to do 2 minute 30 second bulb exposures in Burien, WA location and see pinpoint stars I cannot even see with the naked eye due to the light pollution present here. I'm absolutely astounded, I had not expected such amazing results from a light polluted location and am planning many trips to much less light polluted locals and see what results I will receive there.

Rated 5 out of 5 by from Works as it should, proven weather resistence It takes a few seconds to obtain location info for satellites. On a recent trip to CA, it worked great. I even dunked the K-50 camera with this GPS unit attached in a few waves on a Pacific beach, everything still works great - no signs of salt or water on the inside. I am pleased with this little unit. Battery like is great as well - I never needed to replace it after 750 pictures over 3 days and the same battery is still going strong.

Rated 4 out of 5 by from K3 has some features removed & added The K-3 does not support the Pentax GPS' simple navigation that existed in the K-5 (stated in K-3 manual, destination manager option gone from menu).Some K-5 users had complained that the LED on the GPS was too bright during astrophotography, there is now a K-3 menu option to turn the LEDs off in astrotracer mode.Turning on the compass is easier (press info button twice, to select what is displayed on rear LCD).Flash while using the O-GPS1: Several web pages discuss how to use cables to connect external flash with the hotshoe mounted GPS, using cables.With the K3 supporting manual power control of the popup flash, using fill flash is a bit easier (still using the Pentax hot shoe adapter FG with 5 pin cable and F adapter to GPS mounted on flash bracket).

Rated 5 out of 5 by from astrotracer rocks! not that I know where to point my camera but I am very impressed with the exposure times I am getting with the 200mm kit lens....3060 seconds depending which portion of the sky and how much I crop the picture (trailing becomes evident on heavy crops.....astrotracer is why I got this as I cannot afford an equatorial mount nor do I have to lug around that extra gear and spend an hour setting up...I visit a lot of different sites which is part of my adventure...i get set up in minutes!!!! calibration is simple and may take a time or 2 to get it is a little pricey but i'm glad I got it......all the gps info shows up just fine on sony's play k-50 has the option of turning off the blue light at does work but occasionally comes back on but that's after letting it sit too long without takin a picture

Rated 4 out of 5 by from Neat little product; recommended Nicely made and looks good on my new Pentax K-S2. Does what I needed - location and altitude data on images. Previously I had tried recording gpx files on my iPhone and combining them in Mac's Photos software - yes this is possible so long as you remember to turn on the phone's tracker app at the start of a day, and then off again at the end to avoid the inevitable dead phone. The O-GPS1 process is much simpler - though you still need to remember to turn it on for a photo shoot and off again at the end, to preserve battery life. The AAA battery seems to last a few solid days. The one shortcoming (hence just 4 stars) is that the lever that secures the unit on the hot-shoe can loosen up - twice I had the unit fall off because I hadn't tightened it enough. A bit scary to see your expensive little investment heading across the pavement toward the gutter!

Rated 4 out of 5 by from Jury Still Out on Astrotracer Function I purchased the module primarily for astrophotography, especially for wide-field landscape-plus-stars scenes. When the O-GPS1 works, it's very very useful. Pixel-peeping my results at 400% or so reveals that star images can be exactly round points, with up to a 5-minute exposure with a 50mm lens. On the other hand, sometimes a similar exposure yields streaked images where the stars are about a 4:1 aspect ratio. Fine for the Web, but unsuitable for large prints. While the firmware reports that a maximum 1-minute exposure should be possible with a 500mm, in practice I can only get a few seconds without trailing. Still better than an untracked exposure, mind you -- by the 500 rule, 1 second would be the max.I have yet to figure out any pattern to why it works or doesn't. The direction doesn't seem to matter, I'm pretty sure my technique is consistent. I'll update this if I figure it out.Using Astrotracer is straightforward enough if you're doing a series of identical shots, but if you have to back out of the menu to, say, reset the ISO or reframe with Live View, you have to do a whole button dance to get back to where you were. The built-in timer is very useful, and integrates well with the Pentax Remote F for a vibration-free workflow.It's obvious if you think about it, but I should make note: The sensor shift that keeps the stars sharp (when it works) will blur any foreground in your photo, you'll have to shoot a separate non-Astrotraced frame and do a composite.
