ZorSy: Just what Dilish Parekh needs for his camera collection. The only problem - he would have to move to China to find the wall big enough to hang them ...

Or Mexico?

It would be good to know how capable it is in handling K-1 and K-3 IIPixel Shift images - and with movement correction tool

zakaria: What we don't like
-limited lenses available!?
Really!!
Count with me:
fa 35
Fa 50
Dfa 50
Dfa 100
Fa 31
Fa 43
Fa 77
....
Dfa 28-105
Dfa 24-70
Dfa 70-200
Dfa 150-450
Da 560

Don't forget a number of DA lenses cover FF

DA 35
DA 40 Ltd
DA 50
DA* 55
DA 70 Ltd
DA* 200
DA* 300
....
DA* 60-250

So that's a total of 20 (twenty) current lenses now, and the K-1 is less than one month old.

Plus there's more to follow.

Not to mention a few current third party lenses,
and with an adaptor, 16 current Pentax 645 lenses
and K-mount Pentax AF and MF legacy lenses,
and with an adaptor, legacy MF Pentax 645 and 67 lenses

And it is the DA 40 not the smallest FF lens currently available from any manufacturer?

Pentax are getting there....

Zvonimir Tosic: Incredibly ugly metamorph of a camera, ugly even when considering Marc Newson's unfortunate excursion into the Pentax land. This new camera looks like a cut/copy/paste mishmash of all the models in the last 5 years.
Is this mutilation so necessary, when the user reports never ceased to praise the K5II design? Why not stick to one proven design and change the parts inside? Leica does it, even Nikon and Canon with their top bodies. So one can look at it and say, "Ah, it's a proven Pentax DSLR", and not confuse it with a latest cheapo Sony or whatever.
Do human hands and anatomy change every season so radically, or the marketing manager has run out of ideas how to sell a new model?

The K-01 is a good looking camera, that's why it was awarded the red dot. Not so good in ergonomic terms.
The K-70 is an evolutionary development of the K-S2, with improved ergonomics, both well designed cameras.
Good to see Pentax continuously reworking and improving DSLR design. Other manufacturers will follow their lead, in time.
But I will concede that, in my opinion, the K-30 was as exquisite as an aged camel.

Will it work with Ricoh Theta 360x360 images?

Boss of Sony: How about another Pentax Q or something mirrorless?

Indeed a Q with an evf would be fantastic. Also a K-01 with evf, but sadly I doubt it.

In reply to:

ronniemac: Well researched and conducted review which unearths some of the difficulties Pentax owners have with raw developers not yet quite delivering - or not at all in Adobe's case. Clearly moving water is not ideal for pixel shift, even if PDCU has a fair crack at it. Rustling leaves can sometimes be problematic, but for other subjects, including landscape, pixel shift technology takes image resolution to a higher level. Reworking the bayer pattern sensor so that each photo sensor cell reads all colours of light is a neat idea, smart thinking Pentax!

The upgrade of PDCU provides Movement Control for the K-3 as well as the K-1! As pointed out in the review above, it can sometimes improve on images straight out of the camera. The program works perfectly with Window's 10. Although by default it over sharpens and over saturates relative to LR, this is easily controlled with user settings making for easy creation of tif files for processing and cataloguing in LR.

Good work, DPreview guys!

Good research there, Duratix. I didn't know that Ricoh originally used pixel shift technology back in year 2000 - I wonder if the new tech is partly a result of that 16 year old innovation.
I do agree that Olympus were pushed the boat out further with their sensor shifting technology, but I was careful to state: "Reworking the bayer pattern sensor so that each photo sensor cell reads all colours of light is a neat idea, smart thinking Pentax". I give credit to Sigma for pushing the concept with their layered approach to sensor design in the Foveon sensor, its a lovely idea yet still in it's infancy. What I like about the Pentax approach is that every pixel records all available colour info with no additional hardware or pixels. It's a product of smart engineering within existing parameters.

In reply to:

Class A: Thanks for doing the right thing!

I missed the original article but may I suggest that the updated version not only includes the appropriate processing of the RAW files but also a) includes a still scene and b) avoids high f-stops in order to not limit resolution due to diffraction?

I don't mind a waterfall scene and other realistic landscape scenarios but surely Pixel Shift also has its usages in the studio for completely motionless product shots, for example.

I do agree, some studio shots would be nice, however, Pentax do market their cameras as being particularly orientated to landscape and outdoor photography. I'm happy to see the camera tested in various locations, even extreme ones, so that we can see how much it can do. Always best to test to the limit!

To Simon J & Barney B
Following 200+ comments in 24 hours from DPR members in response to ‘Waterfails: We test Pentax K-1's Pixel Shift’ by Chris Williams, and messages left in Site Feedback, you did the right thing and made a good decision to withdraw the article and “publish an updated analysis as soon as possible”. Anyone who uses Pentax Digital Utility will understand that this could take time – even if it is the best or only program that handles pixel shift raw files successfully – there’s a learning curve.
Barney; regular visitors to DPR who saw your reaction to the K-1 launch on video will already know of your genuine interest in the K-1. I also appreciated your comment Simon: “Mistakes happen - it's how we deal with them that matters. It's kind of ironic because everyone here loves the K1”. A visit to Chris’s website also illustrates that his landscape photography is of the highest order so he should be able to get the most out of this Pentax camera if using the right lens.

To Simon J and Barney B (continued)

Most comments from us readers identified the problems with subject, process, and write up. If some comments were reactionary, it was a response to the headline, conclusion, and Chris’s subsequent posts. It’s time for us all to draw breath and wipe the slate clean.

Speaking for myself, I visit DPR daily because I enjoy the content and trust the reviews as being impartial. I will continue to do this and look forward to DPR’s analysis of Pentax’s embryonic technology which, when used correctly, offer us such high resolution images.

In reply to:

solsang: Thank you DPreview, for providing irrefutable proof that you are an unreliable and manipulative source of information. Now i simply need to link to this article to make others understand that nothing you say or test can be taken seriously.

You deliberately make a critical article with a "hard" mountain climb to only test a feature that a camera is specifically described to be unable to do, namely use pixelshift on a moving feature, which fast flowing water precisely is.

Then you avoid using the supplied silkypix software, regardless of the fact that adobe raw is unable to process the images you take (of the wrong subject) and criticize the cameras raw conversion for lacking the feature that silkepix provides.

After the article you provide a note that you will look into "using other raw converters" not even writing silkypix, yet won't change the article to reflect your errors or include some correctly taken pixelshift photos

The subject should be "Dpreview fails to read the manual"

Except that the raw files they have are exactly not of the subject matter which the pixel shift technology is targeting, (check K-1 marketing text on Ricoh Imaging website).
I'm actually OK with that, provided that other images of the type that best exploit pixel shift are included as well, ideally a range from best suited to unsuitable, i.e. an objective review and appraisal.

Solsang is clearly miffed that DPR have abused their position as trusted evaluaters of photographic equipment for a slick headline. Actually quite a few posters here are, even if we are more restrained in our feedback.

On article Waterfails: We test Pentax K-1's Pixel Shift (225 comments in total)

The following information is provided in Ricoh Imaging marketing for the K-1.
Digital Camera Utility 5
Supported by the acclaimed SILKYPIX® image development engine, this software allows you to browse through captured images and develop them into RAW-format files on a computer. It is compatible with the K-1’s new features, including the Flat mode of the Custom Image function and the Motion Correction function of the Pixel Shift Resolution System.
When the subject is on the move or camera shake occurs, the desired effect may not be obtained.
Motion Correction function
When this function is activated, the camera automatically detects the amount of subject motion .... and minimizes negative effects during the synthesizing process. The movement may not be sufficiently corrected when the subject is moving in certain directions and/or patterns. This function does not guarantee that the movement will be properly corrected for all subjects.

Good idea to test it on a river but W.Y.S.I.W.Y.G.

In reply to:

Favorable Exponynt: The Pentax K-s2 is around 500, but that was probably already in some other round up :p

No mention of the Pentax K-50 either. It is excellent value for money and a true dslr (pentaprism not mirror), plus weather sealed etc. My own preference is for the K-S2, fantastic little camera.

It's really good that you give us choice. The black screen uses less power on certain cell phones, e.g. Nokia 1020, therefore makes more economic use of batteries. Personally I prefer black, but I know many others prefer white.

Thanks for posting this Barnaby, looks like you are having difficulty concealing your liking for this camera, and that's OK. Looking forward to the day I am able to treat myself to a K-1.

Nice that Pentax have added an additional grip (which also doubles as a rotating rear screen!).

In reply to:

bossa: Some Pentax lenses are branded as DA when they are still Full Frame designs:

The DA* 200/2.8 is a FF lens. It is a redesigned FA 200/2.8.
The DA*300/4 and DA*55/1.4 are both also FF lenses.

I'm sure there are a few more as well, but I thought I'd mention this as the DA*55 was listed as a crop lens in the article.

Indeed. There are 21 Pentax lenses that will work full frame, although a few of these will benefit from going down one stop. Pentax forum has new an article explaining this.

On article The long, difficult road to Pentax full-frame (617 comments in total)

It's nice to see so many users of other brands wish Pentax well with the new K-1, and as a Pentaxian I do appreciate their best wishes. Whether out of empathy or from an awareness that competition is good for all of us matters not, but it is nice to know that all users will benefit through competitive pricing and better designed gear.

Of course there are just a small number who are doing their best to dampen down the celebrations for the arrival of Pentax's first full frame offering. Constructive criticism is fine, but trolling isn't and it reflects badly on them. Pentax users aren't effected by the negativity of a few and I hope others are able to see it for what it is. If in doubt it is worth looking up a spoiler's gear list and most recent comments - its revealing. Other than to say this, I prefer to not take the bait.

On article The long, difficult road to Pentax full-frame (617 comments in total)

(continued)
It's worth noting Pentax's marketing policy is firstly to offer something for Pentaxians who want to upgrade to FF without having to sell off all their gear or support two systems, then to provide evidence of an upgrade path for those taking their first steps into DSLR photography. On both counts I believe they have succeeded. Are they trying to take Canikonys away from their chosen systems? Of course not. Manufacturers of photographic equipment respect each other and the individuals who invest in photography gear, irrespective of brand.

We would do well to emulate this respect. Thank you all.
