Duckie: Strange that no sample images.....

You can download 3 full images at the bottom of this page :

PropaPH: the total sensor area of this camera, using 10 exposures, is just a little over one square inch. I doubt that the image quality will be as good as any of the better 1" sensor single lens cameras. The fact that there is a lot of merging and stitching guarantees that the images will be soft in comparison.

Exactly right, but having a 1" or M43 sensor cam with 16 lenses will certainly not fit in your pocket. That is the purpose of this toy not replacing your M43 or DSLR system.

Farmer in the Dell: I applaud the innovation and look forward to receiving my copy. I am an enthusiast, not a pro, and have fun trying new technologies. It is easy to attack innovators, but I would rather cheer them on and contribute to the efforts to make it better than to shoot it down and to forever stand with the status quo.

PropaPH I agree with you, comparing small sensors with large ones is nothing more than a marketing trick. You can download 3 full size images from the company site and see how the highs are clipped, like in any smartphone or small sensor P&S cam, some purple fringe defects etc.
Lots of megapixels is 2D resolution is not the same as dynamic range resolution. I guess some people are still impressed by large megapixel advertisement ?
What matters for IQ is the real effective resolution, measured by how many lines/area the sensor+lens+algorithms can resolve.
I seriously doubt effective 2D resolution would be any close to 52MP.
I believe this gadget could realistically compete with enthusiast P&S cams with the advantage of having several lenses in a small package.
I won't trade my OMD cam for this, don't think that is the point.

Please let me know your experience with this new product.
It certainly seems like a great idea.
I always though that, for smartphones cameras, they could include 3 sensors and lenses one for each color and merge them in processing resulting in a compact camera module with better instant low-light IQ photos.
Lets see if the resurrected NOKIA does something like this for it's new flagship phones.
But this L16 gadget is that idea taken to the limit :-)

Michael_13: What's the point?
You can do this with practically any camera (p&s, SLR) to improve IQ. Some model even do this automatically in a special low noise mode.
My Lumia phone even lets me set imaging parameters like ISO, etc with the standard photo app.
And NO, it does not show what phone cams are capable of: it simply works around their flaws.

Hi Michael,
My Lumia 1020 in manual mode allows to take a photo with up to 4sec exposure time if I well remember, using a tripod I've got nice nocturnal photos. But it does 8x auto oversampling at about 27mm equivalent focal lenght resulting in 5 MP images, not 9 to 10MP like this article explains. Also 8x is far lower than 32x !
Of course the Lumia does this trick automatically but it would take it like an hour to do what the article says. ;-)

cdembrey: I'll buy one, when they become available at the end of 2017. For many people, computational photography is the future of image making.

Digital photography has always been about ones and zeros. The Light will just need a smart-phone style computer, instead of a wimpy camera computer. Nothing new needs to be invented.

The advantage of having smaller sensor is definitely having smaller portable lenses.
They could also achieve really nice tricks. Nokia 1020 small size sensor with 41MP on it can perform zoom better than most single no zoom lens newer phones for example.
Also the same sensor can do oversampling in low light with clearer pictures than my new iPhone.
Fuji's old EXR sensor did similar tricks that actually worked in the right situations.
Many new phones are including two lenses now to go beyond the limitations of small sensors.

But yeap, let's wait and see what they really have to offer when the time comes. So far is nothing more than a cool project ;-)

Interesting idea !
They could develop an App so you could attach the camera module to any phone through a specific case and all computation, internet connection, app upgrades, sharing etc would be done by the phone OS.
Having small sensor devices like the Nokia 1020 and FUJI HS50 with EXR 16/8MP sensor I always though about taking computational photography to extremes using multi-lens gear to compose the final pictures. Compensating small size sensors low light performance by using several of them by doing real-time oversampling or switching to composing high resolution mode when light is plenty.
Having it all in a small package would be welcome.
Hope they have success on this project.

bettyswolloks: I love my 1020. The thing will even shoot DNG!! It even has proper sensor based image stabilization like good old Pentax, you can hear it rattling about when handle it.

True, still using mine.
Add the camera grip accessory and you'll get a better grip, tripod support and 50% extra battery life.

Antek R: This posting is misleading. A microscope is not a DNA sequencer. However, imaging systems similar to microscopes are used in some sequencers. What are you really talking about? Please be precise. Since you say "tissue sample" rather than a processed DNA sample, presumably you mean a microscope, not a sequencer.

Great paper, thanks for the link !

Bilgy_no1: The PureView solution is IMHO still the best way to achieve both great IQ and zoom in a smartphone. The large sensor (1/1.2" in the 808) and downsampling pretty much guarantee great IQ, while the high resolution allows for lossless zoom. All this was enabled by an extremely high standard optical lens. The camera module may not be tiny or flush with the body, but it's much more compact than a zoomlens.

Zoom lens based options have never allowed a really compact phone design and have limited lens apertures. The other option is the dual camera solution, which only has two 'zoom' positions. But these are usually with one sensor being inferior (LG G5) or two small sensors (iPhone 7 Plus). Samsung S7/S7 Edge now has a lens cover that comes with two lenses: a wide angle, and a 2x zoom. Pretty good quality, but with some hassle of lens changing.

Such a pity that the phones that had these PureView cameras were not very attractive on other features. The 1020 was severely hindered by its slow processor, which was a limitation of the Windows Phone platform at the time. Photo processing was way too slow. Also, the platforms themselves were an obstacle: Symbian on the 808 was already in decline, while Windows Phone on the 1020 never took off. For me, that was the reason to not buy them. Then, when I finally decided to give Windows 10 Mobile a chance, PureView on the 950XL was watered down to 1/2.5" and 20MP. Still, that camera is better than the S7 Edge in some comparisons I made.

I do hope that the technology will make it to the market again in an attractive high end Android flagship, now that the Nokia brand is back. Not sure where the PureView patents went in the deals between Nokia, Microsoft and HMD Global. Could be they're still with Microsoft who will let them rot...

I still use my N1020, yes the camera processing is much slower than my iPhone6 but the zoom is unmatched in IQ, leaves the iPhone6 eating dust. I also like the better detail and in low light situations the 1020 is way better than the iPhone6 too.
It doesn't run Win10 but didn't find any need for it yet. As a matter of fact in my case I only miss a couple of Apps every time I switch from the iPhone to the 1020.

On photo No Lifeguard on Duty in the Break the rules challenge (10 comments in total)

Amazing photo !

How did you make the 600 sec exposure time ?
was it continuously open for the 600sec or is a composite of several shorter exposures taken over the 600sec time ?

Don Sata: Too bad, I loved the Microsoft UI but last month I got a Motorola instead because the system seems to be abandoned: terrible instagram app and mediocre FB app for example.

I think the same way about WinOS.

Ubuntu Phone is having the same problem, even being more powerful OS than Windows Phone, Android and iOS. Also having a more efficient, actually working, convergence than the similar (imitation) 'MS Continuum' mode, since it is the complete real PC Linux system with the GUI in Phone or tablet mode, including wireless-convergence which is a big plus :

None of the technological advances seem to be enough for most users against the inertia coming from the huge app ecosystem of the older iOS and older/inefficient mess of Android.

Osa25: Nokia cameras are a bit the "Sigma DP compact" of the smartphone world. It's a bit of a masochist's taste for pain as pleasure....

OH yeah, Nokia N8 was a great device but the OS really bad, the newer Symbian Belle was very good and running smooth on 808.

Windows OS runs excellent on 1020 and newer Lumias, very fast GUI, really like it and got used to it immediately. Even Steve Wozniak preferred it over the traditional (aging) iOS and Android GUIs.

You've *got* to be kidding me! It was because they were running mobile Windows (and possibly distribution issues)!

I actually like the Windows phone Tiles GUI more than the traditional iOS and Android ones. Switched to iPhone because it talks easily with my other iOS devices and NOKIA finished plus Microsoft is killing their phone business.

DStudio, 808 used Symbian Belle which was a solid OS, much better than previous versions, but as you pointed out it came late to the party, iOS and Android were already more mature and with more apps. Never understood why NOKIA released that camera on Symbian OS that was almost retired. I guess it was ready and they just released it as a proof of concept.

Win8 on 1020 runs perfectly and has all the main apps, all camera apps come with the phone, PhotoShop Express free and what else most of us really need ? Basics come preinstalled such as music app, the great OneNote (that I use on my iDevices instead of Apple's Notes that is a joke), Skype, Viber, WhatsApp, etc. all there. Navigation software is way better than Apple and Google, including the quality of their maps which you can download to your phone for off-line navigation. My Nokia1020 works today as an excellent car navigation and media center. Don't miss any iPhone app every time I switch to 1020 when traveling.

On article 8 creative tips for shooting waterfalls (159 comments in total)

Excellent tips Chris !
Great photos, my favorite ones are 3, 7 and 8.
I used your advice and shot each scene with 4 to 6 different shutter times so I could decide later the one I liked.
One thing I always use for long exposures is the 2 second timer, practical and all cameras have it.

Hi Lars, he was right on that interview !
I own a 1020 and the Windows8 experience is very fast, perfectly suited for today's demands, but the camera processing of the huge 38MP files is really slow, nothing that a newer processor couldn't fix of course.
IQ from newer Lumia devices just pale when compared to the 1020, still a great camera specially when paired with optional camera battery-grip with tripod mount.
