dpthoughts: I see two odd things which I dislike.

no 1. it is meaningless to compare a 4-exposure mode like pixelshift to an 1-exposure mode like single-shot in the D810.
If you compare properly, you would do it against a series of four consecutive shots, which are merged in photoshop, with or without the help of an action to automate this.

Then, the alleged noise advantage of pixel shift would be what it is: void ;)

no 2. The K-1 steals its dynamic range advantage by means of cheating (doing denoising on raws). Evidence: the ratio between luminance noise and chroma noise appears to be shifted in favour for choma noise.
If the firmware doesn't do any denoising, then this ratio must always be constant (due to maths).

This is a plausible explanation, why the K-1 will do so well on reviews, w/o having received a new miracle sensor from Sony. Sony wouldn't give such to Ricoh, so that Ricoh's cams appeared as cheaper and better than Sonys own ;) that never happened, of course.

Cheating?? Stealing?? WOW! Somebody is not happy.

Nick Brundle - Photography: I'm sure this is wonderful for Pentax but in the end it's the photographer who composes and captures the image.
Things like knowing your camera, understanding exposure, and conquering composition in my opinion are more important. Just because I have more dynamic range won't help me to compose better pictures.
Not being negative but yet again there is an article about dynamic range

What The Name is Bond is saying that if your camera has a high noise floor or poor dynamic range you are going to end up with noisy pictures that might need tedious cleanup in post, no matter how good the composition is.

He wasn't saying anything to the extend that dynamic range is a substitute for photographic skills.

I partially agree with you but from my personal usage viewpoint this is going to be opening up amazing new possibilities. The way I shoot, (very contrasty, sharp defined shadow and textures ever present in sunny southern california) where I often times have to massively underexpose to avoid highlight clipping, this excellent noise behavior will yield so much better results.
Looking at your amazing photostream on Flickr, me taking similar photos (dark skies) with my Pentax K-3 would have very very much shot noise in it.

That's why I am really thrilled about the K-1 and its dynamic range.

Jack Hogan: Well done. I feel however that to fairly compare noise and DR in captures taken in pixel-shift mode with others, one should first stack four captures of the others.

It might sound fair but wouldn't be. Pixelshift completely bypasses the interpolation necessary to calculate data between pixels as is the nature of the Bayer array. You would still have four stacked interpolated images vs true pixel readout from pixel shift. That is also the reason why these images will create tremendous black and white photos as the scene's tonality is recorded 1:1.

If you are into audio, consider pixelshift lossless (like .flac) and regular photos a compressed .mp3 file, maybe at high bit rate but still compressed. Pixel shift is rawer than RAW, if you wish.

Here is a link to a very interesting French review (link is to google translate to English):

TheEulerID: Excellent results although, of course, inherently only suited to static subjects. I wonder if Sony might introduce something similar on their IBIS equipped cameras.

It also shows what would be possible should it be feasible to produce a sensor which senses all colour channels at each pixel (which Foveon can do) but without a huge amount of colour channel cross-talk (which Foveon can't). A big prize awaits for a company to solve that problem.

nb. Foveon's problem is it depends on a statistical relationship between the wavelength of photons and the depth absorption profile in silicon. It means a huge amount of inter-channel crosstalk which can only be cancelled with large signals. Nasty high-ISO colour in other words.

Even more surprising how many things I take photos of are perfectly still.

I agree, I do a lot of architecture, urban, classic cars etc. photography, it's going to be tremendous for that.

Thanks for the really helpful review! The sample photos look amazing, even at that small size. Great to see what this camera can do in capable hands!

GabrielZ: Pentax's 'Limited Primes' are they FF or optimized only for APS-C?

Of the initial test shots of the K-1 posted here (since removed at Ricoh's request) some where shot with the 70mm ltd 2.4. It fully covered the FF image circle with only some vignetting wide open.
Fully FF usable.

zakaria: I like the conceive and valued report except the conclusion!!!
K1 is not at league with d610 or 6d .both last camera are entry level cameras and outdated. You even didn't put it in d750 league.
The fair compare is D810 at least both are handling 36 mps sensor
Both are 1/ 8000 shutter speed both are well made bodies not a combination of plastic and ss. Don't forget the Pentax unique features that you already have mentioned.

I fully agree there.

Roadrunnerdeluxe: Oh my god! Is he gone?

Yeah, his current account was created February 17th, just in time to troll the K-1 release.
His last comment was (after someone offering him a K-1) he'd send it straight over to "Will It Blend?", I think that's where the admin drew the line.
On a different note, I seriously believe the blender would lose this one.

Anyway, glad to be back under grown-ups again ; )

Okay, Jorge. I love you. I can see you are happy with what you like. Good! Enjoy, my brother.

I've been using my Pentax K-3 for three years now, reliably. I get what you are saying but the advantages it offers beat in-lens stabilization, in my opinion, especially the use of legacy glass. But you know what: in the end it's an opinion piece..and experience. I'll let you know how the K-1 fares once i put a couple of thousand shots through it. I know you use a Nikon D600, a great camera. To me the K-1 is the chance to use something similar to the D600 with my Pentax glass with some innovative features, that's all.

Good, Jorge, good. You just stick with that mainstream offering. It seems that's where you belong. It seems you are happy with that. It seems you seem to really like it. Good! Enjoy! Mainstream. Average. Predictable. Not really outstanding. The same old.
People who like to think outside the box will make use of the new Pentax features and use that new angle to produce amazing photos while you troll around forums praising stale technology. I see where your problem is...and I am sure you know, too.

Roadrunnerdeluxe: A very in-depth, very promising preview on the K-1, titled with:

"Pentax K1: Super Resolution Mode Appears to be Best DSLR Quality Yet"

http://diglloyd.com/blog/2016/20160221_1110-PentaxK1-SuperRes-PentaxFlowers.html

I am especially excited since I do take a lot of black and white architecture shots. According to this preview not only does pixelshift maximize resolution but also will give a true tonality readout and thus absolutely superior black and white photos.

The only true problem I see with this camera is that I will want to take EVERY shot in pixelshift mode once I experienced it.

I am excited and can't wait, to be honest.
