I appreciate a lot of work went into creating these images, but compositing several images, each taken in a different instance of time, is less successful than a single 360 image taken by e.g. Ricoh Theta S or the new Nikon thingie, albeit that image quality with several composited dslr images is of higher resolution. Granted if everyone and everything keeps still it would work.

Oh and the gear is not quite so expensve - by some margin.

On article Shaking up the market: Pentax K-70 Review (332 comments in total)

In response to the following criticism:
".... the silly LED ring around the power switch signaling the camera is on remains.
"If you asked me for my opinion, no, it doesn't look nice. No, it isn't very helpful. No, the switching color between stills and video isn't 'cool', it's cheap, tacky, and detracts from the utilitarian essence that makes a Pentax a Pentax. If any LEDs should be making the jump from Pentax model to Pentax model, it should be the handy LEDs from the K-1 that illuminate crucial parts of the camera for working in the dark, not decorations."
Note the following
The lights are optional and can be turned off from the Wrench menu 3 (on K-S2), so not worth getting upset about really. Others may prefer to have these to indicate the camera is on stills or video. Typically Pentax offers users a choice, no bad thing.

In reply to:

PhotoUniverse: It seems to me that Nikon Keymission is a better option.

The keymission spec is excellent.

Looks like Ricoh will have to offer a better model than the Theta to compete with it, e.g. micro sd card, removable battery, w.r, 4k video etc, although it would likely cost double, i.e. the same price as the Keymission.

At the moment though, the Theta is the better option because it exists. Looking forward to the next version.

FLruckas: Somebody just needs to put this technology in a phone and just skip the external device.

Good questions Leekil.

If you want a selfie in context, the Theta is good for this and I sometimes use it this way. The drawback is that invariably there's a large thumb or hand in the photo, so this is where a selfie stick or monopod is very useful, provided you use a phone to wirelessly take the photo (or a cable switch shutter release).
Other times I don't want to be in the photo, maybe for a landscape or photographing something all around the camera - the cherry blossom tree is a classic. This is where remote control by phone is a must - it enables me to get out of the frame.

Then there are times I want to take photos of subject matter without being in the frame, just leave the camera out there and click when appropriate - good for wildlife.

You are correct, holding the phone above the head is a good idea, but again a monopod gives better results by removing the hand sufficiently.

For movies it's less of an issue because I can delete the start and end when switching on/off.

re Part 1. I do, why presume otherwise.
re Part 2. Because you post it on a forum?

Part 2

Ricoh did not make the Theta S or SC for you 360 selfie guys, but it's what I was looking for and am quite happy with it, thank you.

I'm also quite happy with my excellent camera phone as it is.

Part 1:
All this talk about 360 degree cameras in the phone still does not address the problem of the photographer being the dominant feature of any spherical image, in particular the hand holding and operating the camera-phone. Look at this and you'll see what I mean: http://www.imaging-resource.com/ee_uploads/news/5249/theta-s-feature-image-full__largest-no-more-than-580x630.jpg
Ok for selfies in a wider context, but otherwise pretty useless. Each to his or her own, but there is a limit to how much I want self portraits. A timer can help, but only in a very restricted manner. I don't mind carrying the phone in one pocket and Theta in the other, and to be able to position the camera and control the it remotely from the phone (including shutter, iso, wb, timer, etc). I know this from experience with my Theta S.
I'm sure 360 camera phones will become the next fad, and I'm ok with that, but when it does you will see what I'm getting at.

Well, I have mine in my pocket, when its not in my partners handbag, so no problem lugging it around.
For me these cameras are about capturing an environment rather than taking selfies of myself or my mate. The solution I suggested also avoids a close up of your hand - try out one of these and you'll see what I'm getting at.

The advantage of it being detached from the phone is that you can be remote. Set the camera up on a monopod (with foot) or selfie stick, and step back or even right out of the frame, controlling the camera wirelessly from a distance. Attachment to a drone is another possibility.

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....

In reply to:

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.
