Hm, thinking of this... sounds good! And there is the former Fn-wheel (formerly used to choose the setting to be changed with third wheel) that is now reduced to three positions: OVF, Liveview, Movie. Replace flick of a switch wit click of a wheel and we might be there.

I'm sorry, but there is no speculation necessary what the thing in the blue circle is. It might have been lost in the thread by now but I took the drawing I projected into the schematic cut of K-new from the Patent that describes a new viewfinder. It is clearly labelled as the "illumination light source" and is for the superimposing optical system (information display device).

This is not a real Ricoh drawing, I just combined two not necessarily related sources. Just for the purpose of fun and speculation.

But it is not a sensor, but an emitter. This is clearly visible also by looking at the angle of the optical element below it. It directs light coming from it to the eyepiece.

I agree, there is a lot of space below the mirror box and I would also assume that some kind of sensors are implemented right there. I have no idea if it is possible to implement a measurement sensor, in combining CDAF (or the variant described in the patent) and the light sensor in that. If the coverage of the AF active area will increase, and especially to get light measurements for the whole image, this would also mean an increase of the secondary mirror.

Another possibility would be that the information overlay really might have moved to the light path at the back of the prism and the technology from the other cited patent is used. If the application of this new high resolution combined light meter with AF-capabilities can really be applied to one of the reflective surfaces of the prism this could be a dual AF-system, as some have already pointed out, or at least support tracking and object recognition. This could be the space (prism surface 64) where now AF-points display is, that would not be needed with that.

Regarding your sketch with metering system: No, the indicated places are not the light meter but a "superimposing optical system", probably replacing AF-point indicators and the bottom viewfinder info display in one system.

Here I tried to produce a pseudo-orthophoto of a cut through a k-5. [I used photogrammetric linear transformation of tiepoints identical on the drawing and the image. The only stable points are the mount and the sensor. There are some uncertainties because the sensor shake reduction might have changed since k-5. This image may be an orthophoto for measurements only within the polygon of the tiepoints, there might be distortions outside of that]

What I get as a result is that the optical system of the viewfinder might be higher up than in the K-5. This 3mm further protrusion of the eyepiece are also recognisable. There is more space in the AF-chamber. The front protrusion of the housing above the mount is less.

Please don't take this to seriously, it is just for fun and I wanted to test if my method would work on that.

Right! The construction drawing of K-new shows clearly less protrusion in front of the prism. (I know that the illustration is just schematic, but they used at least coherent scale, my overlay is just for fun and not scaled. Especially the second is not of the K-1, probably a generic APS-C).
In this drawing the light meter is not indicated, (92) is described as the "illumination light source" and is for the superimposing optical system (information display device) and is not the metering sensor (which until now actually sits in the upper part of the exit surface of the prism).

I think we can not derive any information on the resolution of an metering sensor and also the kind of information that can be provided in the viewfinder, but a completely new construction might add some new things. I am am very curious.

Thank you for reposting this here, it is a very interesting read, even if I would claim to fully understand only a fraction of it.

Anyway, has anyone noticed that figure 3 shows an alternative embodiment to superimpose information on the image in the viewfinder? What I noticed is that the space for this system, that normally would be in front of the prism is noticably reduced in K-new. I would not be surprised if they went for this new solution. Whatever the consequence of this might be, we will see.

I am working in research too, and false precision (why do you use decimal mm values if your estimations are +- 3mm?) is a clear sign for me as a reviewer that something is fishy... Anyway, it's not a peer review and you are entitled to use any point you want for your arguments, I see that it is just polemics and would have expected more substance, but, sure, it's just a discussion on an internet forum, what should I have expected.

I thought you are working in science, but if you claim that you 'measured' from this image and used false precision to make your point leaves me somehow disappointed.

May I ask, which cutaway? Do you have a scaled orthoprojection? How come you can provide sub-mm precision?

Still, does anyone really believe him or her complaining in this forum will change the screen of the coming camera? Confucius said: get over it.
It is as useful as the complaints about the lack of flash in K-3 II were. But it sold. And as useful as complaints about lack of flash on GRIII were, or flippy screen there, or viewfinder...
Not every model is for everyone and even if some can't believe it, they still can be great cameras and they might be commercially successful, even if you are not the target group with this model.

I don't think some posts with 'I don't care if it would thicker at the back' can be seen as 'most' people don't care. Almost all people did not have a look through the viewfinder, many people wear glasses and I very much would appreciate to have an eyepiece that stands out more at the back. Especially as the image in the viewfinder is even larger and I have to be very close to see the entire one. Every mm counts and if a flipscreen would mean 5mm more and this would be very unconfortable to use the eyepiece with this magnification factor, especially with eyeglassed people, than this can have been a clear decision.

Expecting K-new - advancements in IQ with recent competition and the effect of the AC

Interesting, the sharpening settings.
However, you might see more differences because this 'tool' offers to compare the images at the same assumed viewing size, thus the higher MP images are always downscaled to the lowest resolution in the comparison. How good this is done is another question, still, it gives an impression, comparable to scaling images of different sensors for a desired print size.
If this pixel peeping is a useful method or not for any assessment may be open for debate. At least there is some control of some variables, but others might kick in. I would not take anything too serious in that.

No. This has nothing to do with Canon. The image comparison tool invited me to compare the new offers to the existing offers in the Pentax line. There was some recent discussion in the news section, a thematic derailment, as so often in these threads. I thought a dedidacet dedicated thread sparked by an image comparison of recent offers in the market might be a much better place for that.

The title should not refer to expectations towards the K-new, but denote a temporal entity - the time while expecting the k-new.

To rephrase and refine it: there have been repeated concerns towards the announced use of an accelerator unit in the imaging pipeline of the K-new. A comparison of Pentax cameras with AU and recent contenders on the market shows that the Pentax approach is not in any disadvantage to the competition in regard to image quality. If the K-new will follow this approach (no expectations here, just knowledge from the announcements) than these discussions would be not only premature, but probably also useless.

You would need two R5s anyway, 20 minutes of filming is at least 10 minutes of cooldown... another reason for dedicated stills cameras

Okay, can't help but keep looking at the comparison.

Conclusions:

the accelerator chip is not taking away the slightest detail. In comparison with the R5 at 12800 Iso the K1-II has less noise and still more detail. In comparison with the R6 and its huge pixels it hast still way more detail and the noise has finer grain.

I am really stunned and looking very forward to the new generation of Pentax processing pipeline.

Yes, right. As a stills photographer I really don't expext the mirrorless systems to give me much improvement in the achievable image. They might have some nice gimmicks for the process of image taking, but I still very much enjoy the ergonomics of a dslr...

bigger pixels or more megapixels? It is apparently not significantly improved in both cases.

The R6 is a 20 Mp FF camera, thus I compared it to the KP. But the R5 is a 44,8 Mp FF camera, and it does not change the situation significantly.

Hi,

I just had a look at the review of one of the recent new kids on the block, the mirrorless Canon EOS R6. In the image comparison tool at the other site I always switch to the latest Pentax cameras, just out of curiousity and to see how the previous (until now still actual) offers from Pentax perform in regard to this new and shiny stills image cameras.

What should I say, just have a look for yourself:

Here the R6 compared to the Z6 and the A7 III:

Image comparison: Digital Photography Review

At base ISO there is a huge difference, with a clear winner, the K1 II. At 3200 ISO the difference in detail is still stunning - again in favour for the K-1 II.
You can play the same game even with the KP, at higher ISO you might adjust for one LV level because of the difference in sensor format and compare ISO 1600 to 3200 FF of the newest generation, but it is holdings it's position very well.
Changing to R5 and other recent mirrorless contenders shows that they can gain a little bit with more expensive cameras, but still, the not so fresh K-1 II is still in the top of the performers in stills image quality.

What does that mean?

As I always claimed: the theoretically possible loss of minuscle detail of AC-pipelined Pentax cameras in comparison with an imaging pipeline without this chip is by far outweighed by the overall performance of the current Pentax setups in comparison with other systems.
If K-new will focus on stills image quality and manage to improve even further it will be a safe thing to claim it reaches FF-stills quality with an APS-C sensor.

Cheers,
M

In the end, we will see, but I am just impressed by the performance of the contemporary Pentax system and somehow I feel confirmed in my assumption that the development of the last few years in the field of mirrorless cameras has not brought any significant improvements in stills image quality.

Isn't that funny. You claim to keep this topic alive by perpetuating an extreme theoretical position, because you are afraid that others, with this extreme theoretical position will bash a new camera that does not fulfill the generic rules of this extreme theoretical position. By this you program yourself for disappointment, because you proclaim a solution that did not get a single positive clue to be fulfilled by the manufacturer in its next camera. To the contrary, the pre-raw processing pipeline might include hardware already known and used by this manufacturer and they seem to be quite confident that they can deliver flawless image quality. Your position would not allow that in any case, even if you have absolutely no practical evidence that this decreases the image quality the slightest.
Good luck with that, I don't see any exit scenario for you if you continue your way.

Are you really asking that? Geez.
In the Pentax system you will be able to have a two body setup and cover all the flippy dreams, nightscapes, macros etc. and now will get an additional camera that can act as a teleconverter, allowing a similar view through the viewfinder for the situations the K-1 has been lacking, fast AF and burst shooting.
But sure, you can also bring your MX with you, whatever floats your boat.

Uhm, the implementation of a viewfinder that allows an APS-C camera to show an image the same size as a FF-camera normally shows is not a simple new prism.

The linked version is for GR III on Amazon.de.
No guarantee though on the impact on battery life, but for me it works well.
