On article Pentax K-1 Pixel Shift: An update (96 comments in total)
In reply to:

howieb101: First, thanks to DPReview for deciding to re-visit the original article.

I think a better slant to the article (that has been suggested elsewhere) is to choose subject matter at increasing levels of movement and show the weaknesses or tradeoffs of using pixel-shift. The user can then decide where their own personal limit is and whether pixel-shift is useful for them, if at all.

If DPR really wants to get involved they could mention recommended best practice post processing techniques or at worst lead users to an alternative source where users are using pixel-shift to their advantage.

Rather than trying to categorically say the feature is good or bad or a write-off or even fantastic, it can be written to be open ended. You know, the pluses, the minuses, best practices, alternative sources of information and un/successful use cases.

Continued in next post...

A lot of people already know its limitations. It's whether the benefits are sufficient for the effort the user invests to reap those benefits. Ultimately, this is not objective. It is actually subjective (as every user is different and willing to go to different levels of extremes to get the shot!).

brycesteiner: I get the point of Pixel Shift on Olympus: It gives 4x the resolution of the standard sensor, but I don't get the reason in this camera. At 36MP it's fantastic already and I don't see that it will have 4x the resolution like Olympus. So what is the point of Pixel Shift on this camera?

Here is the website:
"The K-1 uses the latest super-resolution technology, which captures four images of the same scene by shifting the image sensor by a single pixel for each image, and then synthesizes them into a single composite image. Since the K-1’s SR unit has a flexible design that tilts the image sensor unit in all directions, it provides a host of handy shooting functions, including auto level compensation, image-composition fine-adjustment, and ASTRO TRACER, which simplifies advanced astronomical photography using a built-in GPS module."

The camera looks amazing. I'm just confused on what Pixel Shift does because from the comments it doesn't sound like the picture is 4x the size.

Hi. This probably explains it best:

Basically it removes the need for data interpolation (educated guesswork/ computer programming algorithm) of color that is inherent in Bayer sensor design and instead you are actually recording the full-color information that exists.

The green footnote is misleading by excluding important and highly relevant information:
ACR introduces a color cast;
ACR does not support pixel shift.

Add those and be honest and explicit about it. Hiding behind the explanation that the test has been done with ACR when it is not fit for purpose is...deceptive.

To anybody who looks at the images, I suggest they click on the supplied link by Ari to see why using Adobe Camera Raw in this article is literally a joke.

The images speak louder than words very clearly.

Alex Sarbu: Soo... the article wasn't corrected nor retracted. DPReview is insisting on putting the blame on Pentax for ACR not supporting Motion Compensation.
It's no longer a mistake. It's lying. It's stupidity. It's incompetence. All the good attributes DPReview wants to be associated with.

And misleading.

I really think the green note, at bottom of article by DPReview should be clearer that Adobe Camera Raw (ACR) is the cause of the color cast. It just says that it is using ACR without clarifying its negative impact on the images.

On a side note, I have read many user reviews at BHPhotovideo and actual buyers of the camera seem to like pixel shift resolution. Each to their own, I guess.

I think this article is really a side track. You have to know when to use pixel shift and what its limitations are. If you can work within its limitations you'll get real benefits otherwise its a feature on the camera you can choose to ignore.

Personally I can see it useful for still life, certain types of landscape, macro, product photography and architecture.

Lan: I think this would have been rather more interesting if it had been compared with a different camera as well - say an A7R? They're roughly comparable in price at the moment.

Based on these samples I'd say pixel shift isn't worth the massive increase in file size.

Well the user can decide the cases when they think they will benefit from pixel shift and shoot in normal mode at any other time. Just saying.

On article Sony Cyber-shot DSC-RX100 IV Review (1602 comments in total)

I think these reviews do not make a fair adjustment for price. If you sell an expensive camera it has to be fully featured to justify its price.

Lots of less expensive cameras get marked down based on missing features. Oh, but its several $$$ cheaper.

It doesn't seem fair lots of the time.

The Rx100 IV certainly seems to be about as good as you can get for a one inch sensor but you are paying for it literally.

At circa US$1000 I'd say it is a fair price only. Definitely not staggering value for money.
