This is really cool, and will put Pentax into another nice, exclusive niche. I'm on this as soon as it comes out. $250 for this is a steal.

maybe with the 14mm 2.8 or 15mm, but once you start going over 18 the stars start moving pretty fast.

I would have rather had this device with a sync cable to a electronic mount so if can adjust the mount for as long as you want to do the photo for and not move the sensor at all.
While I don't expect to get the full effect Pentax claims, I'm willing to bet the actual numbers will be closer to their claims than yours.

Re interesting use of floating sensor, was just thinking that if they somehow also made the sensor rotate, they could make quite a cool in-camera tilt shift. That'd be trippy.

Has anyone seen any release dates yet? I've seen 25 June mentioned a couple of times and the more diffuse "July".

Pentax to announce a new GPS unit for DSLR cameras (O-GPS1) | Photo Rumors
and
Re: Pentax adds GPS unit with Astrotracer: Pentax SLR Talk Forum: Digital Photography Review

OK, at first glance it looks like your standard GPS unit.

BUT:
Astrotracer for astrophotography
The O-GPS1offers the advanced PENTAX original Astrotracer function,* which works with the PENTAX Shake Reduction (SR) system on select cameras for tracking and photographing celestial bodies. The unit calculates the movement of stars, planets, and other bodies using the latitude obtained from GPS data and the camera’s alignment data (horizontal and vertical inclinations and aspect) obtained from its magnetic and acceleration sensors. Then, the unit shifts the camera’s image sensor in synchronization with the movement of the object(s). As a result, stars and other bodies are captured as solid points rather than blurry streaks, even during extended exposures. The unit also simplifies astrophotography by requiring only a tripod and eliminating the need for additional accessories such as an equatorial telescope.
  • This function is available only when the O-GPS1 is mounted on a PENTAX digital SLR camera body equipped with a magnet-driven SR system.
The duration of Astrotracer operation may vary depending on photographic conditions.



SO COOL

Yes, it's cool but it's just cool.

Fixing bounce flash overexposure, tethered support would be very useful, not just cool...

It's confusing me, but it'd be great to have sorted out one way or another.

Nevertheless, the O-GPS is a useful tool, not just cool - but clearly not for everyone...

I think it's a cool accessory, but way way way overpriced.

I don't know bout that. Most telescope motor drive tracking mounts with GPS functionality are pretty expensive things. Do you know of one for $250? Sure, a real tracking mount would be more flexible and allow for much longer exposures, but the cheapest I've seen is this one from Orion. It's only $159.00 minus S&H with motor drive and all. But it doesn't have GPS so it needs a bit more fiddling to get aligned properly. If do know of a cheaper solution, please do tell because I've been looking for one.

You're comparing a specialised motor drive tracking mount with a GPS system that additionally moves the sensor a bit to stop stars being blurred on relatively short exposures

I would wager that most people who want a GPS facility for their cam have no interest in shooting little white dots on a black background ( )

A lot of mobile phones have GPS and as mobile phones sell in the millions then the technology for GPS these days is dirt cheap.

Don't get me wrong I'm not knocking the product feature wise, I just think it's way way overpriced and frankly I think the next Pentax DSLR ( K-3 ? ) should have GPS built in.

Of course if it's worth the 250 shekels to you then I would respect that.

But beside position you also get direction, that is "new" as far as I know. Maybe those interested in position also likes this bit of extra info. (I don't really know as position isn't that important to me.) If they don't they can use any cheap standalone GPS and sync when they get home.

I'm however interested in the white dots on the black background thing and will buy one if early reviews show that it actually works well enough.

This is a clever use of overlapping tech, but it's practicality needs to be demonstrated. A program like RegiStax works well to combine short exposures into a single image. Will GPS controlled sensor shifting do it more easily or better? How long an exposure of, say, the moon at 1000mm will sensor movement permit?

Nikon GPS GP-1 is at $265 will less function than the Pentax
Canon do not have one but you need to buy a USB wireless who is $729

Do you know that all DSLR accessories are expensive if you buy the brand name??
