Somebody on the dutch forum opened it up: Pentax O-GPS1 inkijkje.
Those two large processors are probably the crux of the space taken inside the flash housing. You can manipulate the board to reroute the pathing, but unless they replace those two pieces they aren't going to make it much smaller.

Ok thanks.
Because we literally use Lightroom and other program for "demosaicing" a DNG file which means "interpolate" existing informations to create the one missing in the file since we don't have all the R G B vlaue in a normal DNG file. So, with a file containing ever value, there is no point in demosaicing it so program like Lighroom are useless and that explain why Sigma never find a solution for their file but only their own program... So yes I'm very curious to see how Ricoh succeed where Sigma fails...
I can't answer those questions, since i have 0 experience with this But will pass on any questions to Ricoh!

AFAIR, Lr opens Olympus HiRes files...

Do we know if the hiRes mode can produce a single DNG file ?

I thought it was possible in PS with a special plug in only...

I've read somewhere it works with Lr 5.7 and 6/CC...

Maybe they can optimize processors, so instead of using one for GPS and one for camera, they can use one for both. And antennas or whatnot can be expanded over the whole camera body as well. I think built in GPS should be more effective. But it will be a drawback for those who don't want GPS or don't use it, because they will be paying for it anyway. Same logic goes for Wifi. Pentax just decided that this camera will be for people who want those solutions. If people want a flash instead of GPS and Wifi, buy one of the other Pentax cameras that has those features.

It would be great. But what makes me doubt for Pentax is that they shift one pixel to have RGB value for every pixel. Olympus move HALF a pixel so you really increase the number of effective pixel so they need a demosaicing after all... unlike Pentax files. But Sigma files (same tech as Pentax) have never had any solutio (at least from Adabe which is the leader is RAW demosaicing)

And it sure didn't sell like crazy. Clearly, the popup flash is what killed the K-01.


Correction...


Sony and Fuji APSC mirrorless: Sells like crazy.
Pentax APSC mirrorless: Sells like crazy after fire sale.

I rarely have used the onboard flash. When I need a flash I either install one in the camera or I use triggers snd off camera flash.

To be honest I wouldn't be surprised if the K-3 II successor has a flash again, as they have found a way to fit the GPS module, WiFi and NFC into a body that was designed for those features in the first place.
Which DSLR model has GPS/WiFi/NFC ?

Could be more of a "can't be bothered" thing rather than not being able to do it. It costs Adobe time and money to figure out the Sigma files, and who owns a Sigma camera?! Of course this is going to be a bit of an issue for Pentax too, cause the number of cameras that can produce these files isn't going to be small.

Raw files are IIRC usually greyscale TIFF images, and Lightroom knows which pixel should have which color and then interpolates what pixel should have what color. DNG files are basically such greyscale TIFF files in a certain container (defined by Adobe) and compressed with a certain compression algorithm (actually only the decoding is defined I'd guess, how you implement the encoder is up to Pentax, Adobe, ... that's why a DNG file from a K-5 can be compressed lossless in Lightroom and ends up smaller). DNG AFAIK does support full color TIFF data that doesn't have to be demosaiced, it will be bigger (obviously), but that's it. Hopefully it's not hard to implement for Pentax, they would just have to add up the 4 photos taken... I think? Then pack that in a DNG container and Lightroom hopefully reads it. I'd be surprised if Pentax didn't do that.

You can look at the K-30 and K-5 internals here:
Pentax K-30 vs K-5 IIs Cross Sections - Photokina 2012 | PentaxForums.com

I suppose the K-3 will be similar to the K-5...? The chips in the OGPS-1 might fit in there...? With some effort? But the problem is that part of the body is metal... not good for the antenna. Maybe if they had placed the antenna in an extended flash enclosure made out of plastic? If Pentax were to design a camera with GPS from the ground up I would expect them to be able to fit GPS _and_ a flash. But this is different. And maybe they are also hoping to see how people will react to the loss of a flash... if the reaction isn't too bad, maybe they have other plans for that space (Hybrid viewfinder? Please Pentax?). Otherwise, this is just a temporary filler, and the successor will have a flash.

NFC doesn't have to be at the top of the camera, it can be placed like in the K-S2. And the D5300 has GPS and WiFi. Yes, no metal body, but with a new body Pentax might have a part of it (near the hotshoe?) made from plastic, so they can fit antennas there? I'm not an electrical engineer (though I was heading in that direction, once... but didn't get too far... all that math...). Not being able to change anything apart from the flash housing itself must have limited them quite a bit.

For info, in comparing the K-3 and the K3 II body, it seems they only made a few minor alterations (circled in red) to the metalware of the new camera.


And the changes required some modification to the WR sealing too:

Sorry, you implied Pentax had already included all three with another camera. I'm not interested in what Nikon does, their body engineering isn't in question.

Ah, sorry. No, I meant that when they design the K-3 II successor, and they decide to give it a new body, then they may be able to fit all these things into a body that has a flash.

@rawr: Interesting that they did change the metal parts...
