I have read mixed reviews about image quality. Seem that there is some variation in quality from lens to lens. I hope that Ricoh brings the ultra-wide that they have on the roadmap to market very soon. That said, the 15-30mm looks like a great lens for this type of work. At F/8-f/11 it is very good.
They/we need a TS lens for architecture. The Samyang is stopped down quiet good on the A7rII according to Forum member at getdpi who's judgement I trust. I will ask him for a file.
In deed the 15-30 is a must have lens for the K-1.

BTW There is some Built in rise and fall and shift, albeit very minimal 1.5 mm

Built in rise and fall and shift
Pentax calls this Composition Adjustment. Using the anti-shake mechanism, the sensor can be moved up or down (rise and fall) or left or right (shift). While the amount of movement is limited to only 1.5mm, this can be quite helpful with a wide angle lens or with closeups. In theory, if there is 3mm of range (1.5mm up and 1.5mm down), it should be possible to make 36 X 27mm images with no parallax issues (or 39 X 24mm images), Odd that Pentax doesn’t automate this, stitching the images automatically into one raw file, ideally also in SuperResolution mode.

Yes but the K-1 is in a different and more serious FF territory. For architectural photographers this is quiet interesting to have this extra level in sharpness.

Whilst I agree that the majority of K-1 owners (like the majority of K-3II owners) won't use pixel shift (or certainly not very often), I disagree that it was a "gimmick" on the K-3II. It certainly has limited applications due to the need for entirely motionless subjects, but for product and still life photography, it works very well indeed. The main issue was the lack of clear documentation and initial lack of post-processing software support, which I believe put a lot of people off using it on the K-3II. I don't use pixel shift very often, but I've taken a handful of shots with it that I'm very pleased with. The K-1's improved implementation should make it an even more useful feature.

I fundamentally disagree with making such a statement. How are you able to project the members of the group 'most K-1 owners' ?

I used it often on the K-3 II and will on the K-1 - it's wonderful for still lifes and close-up photography. I'll be trying it out on landscapes too, with a tripod. I certainly don't regard it as a gimmick (to me, video in a DSLR is a "gimmick" YMMV). I really don't know why you say these things, Ron.

A "gimmick" enhancing your pictures up to medium format level in terms of colour rendering and dynamic range... and improving it substancially for noise and artefacts...


Yeah, K-01 is good enough.

I was at the dentist today. Some waiting time and I looked into Harper's Bazaar magazine. Full of images, and most of them are comercial images for some kind of product (dress, clock, parfume. ...). There are maybe some images in made with Hasselblad or Phase One. Most of them are made with a full frame camera (so there is a bright future for K-1). All these images have got intensive work done in some computerprogram to make them look excellent. That is also where the most image quality enhancement can be made next to having a great camera. The work flow with files from pixelshift is way to complex to be used in any professional way. There is enough room to work with an image inside the DNG raw file that the K-1 and other camera's provider.

So there is maybe some use for pixelshift, but outside of hobby photography I don't see it getting popular. For the amature it probably is something for a few users.

I would say for almost everything, as long as it doesn't move.

All those images were made with cameras costing significantly more money using workflow creates before the advent of Full Frame Poxel Shift. Let's wait and see what develops.

That is the thing. Costing much more......

Look...

So basicly the Sony is the sharper lens, but costing twice the Pentax......

Once you are paying the person working with images, you have very quickly earned back your money on the purchase of the lens.

There is a large number of photographers who work in architectural photography. Interior designers, architects, home builders, and commercial contractors all hire architectural photographers to create images. Pixel shift is the perfect feature for this type of photography. Ricoh just need to release the right lens for this type of work.
I get the tilt shift, I don't get the PS honestly... To me it would mean that theses standard 36MP are not enough, that 300dpi with A2 and 150dpi with A0 is not enough...

I don't see all the guys in theses businesses spending their time giving magnifying glass to their clients and say: "The flat may be terrible or this interior design sucks, but look how you can see the fine details on this print... Really you should buy from us... if anything we have higher resolution pictures !".

Really nobody care except the photographer.

If you plan to print like 100" wide and expect people to stare at it from near distance, nitpicking on picture quality, yeah it will make a difference. Other than that... well, I don't really see the need.

Amazon give me websize picture for what I buy. If I buy a magazine, ads are like maybe 8x12", at best 12x16" where I'll never see the difference between 8 and 36MP already.

Even if I get a high end catalogue for some product that may cost 50K€, even a car, I may get an A4 brochure in the end. Simply because manipulating A0 or even A2 material is not practical.

If I go to cinema, standard is 4K, 8MP...

While the actual technical achievment is interresting, while you can use it on some occcasion (already quite limited). The time were it will make an actual difference to the final product: the ads in a magazine, the actual printed photo on a wall are almost immaterial.
Perhaps, and perhaps not, Nicolas. The fact remains, it's a clever feature that is available for those who want to use it. I'm sure there are fine art photographers for whom pixel shift is very useful

From your earlier post you said "nobody cares except for the photographer". You could well be right, but if the photographer cares, the capability is more than justified

Pentax's PS is not just, or mainly, about resolution. It does away with the Bayer interpolation step. The color signal at every pixel is a directly measured value using PS*.

Without PS, the color signal for 2 out of 3 colors at every single pixel is a guess**. Which would you rather have, a picture with 2/3 of the color information a guess, or direct measurement of all color data?

* PS implementations other than Pentax's (e.g. Olympus') may not have this advantage.

** Granted the Bayer interpolation probably gives a good guess in many cases, but it is not a direct measurement.

But you made an assertion about dSLR workflow, not Mirrorless lenses. How are the two related?

I work with people who do care or they wouldn't pay me. This is not simply about resolution. We are talking about a 2EV improvement. We are talking about better color accuracy. I was at a 13,000sqft house today where the interior designer flew in from San Diego (4 hour flight) just for this meeting at this house. The interior and exterior photography package will be over $6,000. The house won't get staged and the landscaping won't be ready until spring of 2017 and they are already 18 months into construction.

We are not talking about $600 wedding packages. We are talking about people who really care about the little details. I have not shot interiors and architectural since before the recession in 2008, but I use to work with the builder a good bit and if Ricoh has the right gear I will price the project for him. I was shooting Canon at the time and renting a T/S lens when I needed it. The K-1 is really the perfect camera for this type of work. I just need the prefect lens.

Interesting. For that kind of $ the customer will have justifiably high expectations.
