WOW!

Appart from landscapes and architecture - has anyone tried pixel shift on portraits? Do models have to be "super" still for it to benefit? Waste of time?

Thank you.

You really don't want that level of sharpness anyway with a person's face. I regularly shoot portraits with the K3 and the FA 77 Limited, and sometimes I actually turn on the AA simulator because it resolves TOO MUCH detail. At 36MP you'll spend hours fixing bumps and skin blemishes, if you want to be thorough about it.

@PKDanny I have a kidney standing by for when they start taking pre-orders.

@ecka84 It's just something about the rendition of the image, something subtle. Notice how the front of the bike just jumps off the screen. People sometimes talk about a 3D effect, some folks call it pixie dust, but whatever it is, the FA Limiteds are known for having it. Jun Hirakawa wrote a paper years ago talking about the philosophy behind the optical design of the 43 and the 77. He intentionally left some of the field curvature uncorrected. He claims that this improves the transition from in-focus to out-of-focus front to back. Most modern lenses are almost completely corrected for field curvature because designers want their lenses to perform well on test charts. The analog in education would be "teaching to the test". The FA Limiteds have a certain characteristic "look" to them that you tend to find in good cine glass, easy to spot but hard to describe, a small amount of aberration that is actually pleasing. As Marilyn Monroe observed, imperfection is beauty.

On article Pentax K-1 Pixel Shift Resolution: Updated Field Test (209 comments in total)

In a larger sense, this is an interesting study of how much the interpolation process necessitated by the use of a Bayer array reduces resolution. Think of how much more information could be squeezed out of any given lens if a Foveon sensor could be perfected.

gianstam: Dear DPR... Is it possible for you to do a handheld test of the pixelshift? Using the standard lab sceen?

Although the ghosting problem with pixel shift has been improved from the K3ii, hand holding is probably not a realistic expectation. If something in the frame moves between shots, the camera will mask it out, but if the entire frame moves, as it would when hand holding, there will be very few pixels that don't require masking. In other words, it's ok for your subject to move a little, but not your camera.

Here is a video of hand held PS on a pre-production K-1 model, but sadly we can't see the image files. https://www.youtube.com/watch?v=-nZvfSx7ZsU

TwoMetreBill: Were the K-1 an all electronic camera with a global sensor (IE mirrorless and no mechanical shutter) then I'd switch from Olympus. The improvements are significant but not sufficient. This could be considered pixel shift version 2, waiting for version 3.

The shutter only opens and closes once for each pixel shift composite image.

MSullivan: People complaining because the Hi-5(!) setting on a camera looks like crap. Lol.

Well yeah, I know no one ever shoots at those sensitivity levels in real life, but why even include a High 5 setting if it's going to look like an analog TV with a broken set of rabbit ears? And apparently from the other article they did so at the expense of dynamic range. I have nothing against Nikon, but it seems like they have a $6.5k blunder on their hands.

Those are some nice images... if pointillism is your thing.

I don't have instagram, and have no plans to join, but it seems to me that this decision should be left to the individual user.

AndroC: "Ricoh got back to us as of March 3, 2016 and has agreed to allow us to publish the K-1 samples here at a resolution of 2000px on the longest side."

Speaking as somebody who is keenly interested in moving to the K1 from my beloved Sony A850, I am disturbed by the question of why Ricoh is restricting resolution on published images. After all, it is only a matter of two or three weeks before the camera is available - are they seriously going to make firmware changes in the short time before that, and produce stunningly much better images? I find this strange. Would it not be more convincing to show the full detail of what this camera may do?

Hehe, yeah, things are a little different in Ricoh land. For instance when a new camera is about to come out, they will stop production on the model being replaced, sometimes 4 to 6 months in advance. This always freaks out newcomers from other brands, and manages to contribute to rumors that PENTAX IS DOOOOMED!!

dosdan: Cary, I understand you only had a few hours to use the camera. But there's some nice features in Pentax cameras that make the shooter's life easier.

For example, in your "Pentax K-1 Pixel Shift Resolution demo" video, you zoomed in repeatedly to check the effect of the pixel-shifting. If this camera is like earlier Pentaxes, when the review image appears on the back LCD, you can just turn the rear dial (now used for zooming) 1 click to the right.

Rather than going 2x, 2.8x, 4x ... 16x to check the focus, you can preset the first-click amount. On my K-3, I've set it to 8.3x (100%). So I get a very convenient jump to 100% pixel-peeping for focusing accuracy. Once there, left-turning the dial zooms out (8x, 5.6x etc), while right-turning zooms in (11x, 16x), and pressing the OK button on the back returns you to 1x.

Your current zoom level & panning position (e.g. lower-right corner) holds as you use the front dial to move through reviewing shots.

All very sensible.

Dan.

@Dan I like that feature too, I just wish they would combine it with face detection (where applicable of course), so that it would zoom in on the eyes rather than the center of the frame all the time. Maybe the K-1 will be the camera to do it.

I've used catch-in-focus on my K-3 to capture runners as they cross the finish line. Great feature, you just pre-focus and stand there holding the shutter button. It almost feel like cheating. Haven't tried birds in flight yet, but I bet it would work.

(unknown member): The old K-1 or the MZ-D as announced originally is one beautiful camera!
I am not crazy(and not a hipster lol) - it's just my taste I guess - it is beautiful to me.

I always thought the MZ-S was really weird looking, but at least they didn't go for the PZ-1p look (i actually own one and it's a fabulous camera, just ugly as sin)

Come to think of it, Pentax has a history of some ugly puppy cameras. the MZ-S, the PZ-1(p), the K-01, the K-S1, the SF1, the original 645, the 6x7 (ca. 1969), yet they are strangely endearing.

Class A: Almost everyone unfamiliar with the Pentax lens line up severely underestimates the amount of available FF lenses.

Of course, first there are the new zooms, covering 15mm-450mm. But the list continues:

There are not only some "D-FA" lenses (like the 100mm macro) that carry a "FF compatible" designation, but also (around seven) "DA" lenses that have been sold as APS-C lenses but produce an FF image circle. The DA* 55/1.4 is just one example.

Then there are of course the three Ltd lenses (31/1.8, 43/1.9, 77/1.8) which, despite being initially developed for film, easily outresolve 36MP. These are available new, and if one extends one's search to the used market then there are a multitude of gems available, all AF capable, supporting metering and 36MP compatible.

That's not even counting third-party glass, e.g., from Sigma.

It is just not true that the lens selection is meagre. That argument only applies if one restricts oneself to silent focus lenses with a built-in motor.

People like to complain about not being able to purchase lenses that they have no intention of ever purchasing anyway. The also like to complain about slow primes when they've never shot any wider open than f/5.6 because that's where the test chart says their lens is the sharpest.

keeponkeepingon: Gosh what a name. Every time I see K-1 I think K-01 The the lovely little brick that produced great images but everyone loved to hate.

Let's hope that this new foray into does a bit better.....

Agreed, people might have been able to get over the K-01's brickishness if it had an EVF. Not me, but some people.
