Here is why Nokia EOS uses a mechanical shutter for the camera

The Nokia EOS has leaked out extensively last week and one peculiar feature in the camera superphone is its use of a mechanical shutter…

me too.......and now there is no down thumbs for vote.....!!!
EOS will have more MP than 41. who know.

Well at least Nokia is trying out something new, thats not incresing display size, megapixels, or cores.

they did increase the megapixels.. in a good way

trying something news? what new?

That's not new!Camera on my Nokia N73 looks very similar.

You might want to think about getting your eyes checked before getting a new camera.

and imagine sony and samsung makes DSC and still can't beat nokia when it comes to cameras on smartphones, nokia is always good

Let's get real here, how many times (say, out of ten) would you use a humongous 41 mp setting for casual snapshots? I have a 32 mp full-frame NIKON and rarely use it at its full res due to hardware constrains on my PC and laptop...
The sweet spot IMO is 16-18 mp (if not used for billboard-sized printing)...anything higher than that is overkill

in marketing, bigger numbers looks better.
32. chaoticrazor (Posts: 2347; Member since: 28 Aug 2012)
you mean like samsung and its octo-core, just bigger numbers
you missed the entire point of the 41mp sensor as your trying so hard to play down the massive step forward nokia have made with this type of camera
besides why do you never say this stuff when your worshipping samsung? they market like hell

i want to explain in 'murica language but this is better.

you know limited about nokia 41mp i guess its the senor thats 41mp the actully pic is downsampled to 8mpix so its same pic size in mb as any other pic of modren phone cameras
14. aelliott (Posts: 25; Member since: 01 Oct 2010)
With respect, you are missing the point.
The 41mp sensor allows for "lossless zoom" - so, without a mechanical zoom, you can zoom in with no appreciable loss of picture quality. Other cameraphones with digital zoom cannot do this.
Secondly, if you just want photos of, say, 5 or 8mp then the camera uses the extra pixels at its disposal to make the photo more accurate by combining them (excuse the non-technical speak!!).
Finally, assuming it's the same sensor as on the 808 Symbian, it is a MUCH larger sensor than on any other cameraphone.

@FlushGordon.. please read something about pureview and EOS.. don't be a dumb. You said you are a professional photographer yet you didn't read about this Cameraphones... Sick!!! I want to thumb you down but i can't do it..
21. raphz (Posts: 35; Member since: 22 Oct 2012)
read 41 mp pureview pixel binding technology first and then you will understand ....
its not only snap 41 mp picture
29. Crossblade (Posts: 190; Member since: 21 Apr 2005)
You have 32 million of high quality pixels. The 41mp in the phone are used to deliver 5-8mp of quality image ;) Nokia suggest that people should not use the "full resolution photos" and shoot at the default "PureView" mode which delivers lower resolution (5, 3 or 8mp for the 808 PureView).

And you call yourself a wedding photographer? You have no knowledge how the 808 uses its 41mp!
Plus higher than 18mp overkill? why? because android doesn't have it? don't see people say 1080p screens and quad/octa core processors is overkill! but in this case Nokia ACTUALLY USES THE 41MP!
36. jsdechavez (Posts: 708; Member since: 20 Jul 2012)
Well, there's the Pureview modes that do superpixels.. The lower the output resolution (full 38 MP to 3, 5, 8 MP), the better the details. Only pros and post-processing require full-res captures I think.

If my sensor had 41mp I would use it for every single shot (even for a 4mp snap ) because *not* using all 41mp means it's not capturing all of the available light and ~information~ of the image.
So, your point about how often a 41mp *final* resolution is rarely needed is totally valid, but it doesn't discount the need for a 41mp sensor for every shot -- so really the follow on question is "why is a 41mp sensor useful for a low-res final shot?". I don't actually know much about pureview, but in general the answer lies in the benefit of --oversampling-followed-by-interpolation-and -downsampling-- which are staples of --discrete-(e.g. pixel)-signal-processing--. I probably wouldn't do a very good job explaining it, so I would encourage you to search around. But imagine two diagonal pixels of a 4mp sensor, each resolving to a color, now imagine chopping each of those into 9x9 sub-pixels of a 41mp sensor (each with it's own resolved color). Then you can create a better final 4mp shot from the 41mp pixels by averaging them to get to the final values for the two diagonal pixels of the 4mp image (this is called "interpolation").
There is another advantage of oversampling in that it can mitigate an effect called "aliasing", which is more difficult to describe without images/drawings.
There are actually many other cool signal processing tricks (e.g. ultra-pixels) which are difficult to explain but offer advantages and tradeoffs, and so instead of getting caught up in marketing hype it is better to evaluate the tech by comparing final images of a controlled test, right?

Where the hell is thumb down option?
35. daniel_bargs (Posts: 325; Member since: 27 Nov 2010)
how much is the size of the pictures... even though that has 41 MP... i think ill just use an 8 mp if not that important....an 8mp already costs 1.5mb! 41MP might be 5mb-8mb already haha :)
37. jsdechavez (Posts: 708; Member since: 20 Jul 2012)
Good choice.. Better noise-free photos too the lower you go with the Pureview Pro Phase 1

Hats off to Mr. Damian Dinning. He knows his stuff. Hope he goes back to Nokia...perhaps in better times.

And now we know why the EOS line will always have a hump - the mechanical shutter + xenon flash.
But then, why doesn't the L928 have a hump? It is equipped with a xenon flash. (confused)
40. sbw44 (Posts: 404; Member since: 04 Dec 2012)
Just wanted to ask that question, but according to GsmArena's review of the 928 it seems the Xenon flash does not do the job and they even say that it may have been implemented wrong. So maybe the 928 does not have a powerful Xenon like the 808 or n8
48. aelliott (Posts: 25; Member since: 01 Oct 2010)
The L928 doesn't have the bump because the sensor is smaller, not because of the mechanical shutter or xenon flash. It's the size of the sensor on the EOS, 808 and N8 that requires the bump to fit it in.

Everyone, good job for being positive. All thumbs up!
43. lubba (Posts: 1311; Member since: 17 Jan 2011)
Wait a minute! There's no thumbs down! Its ok, I don't miss it.
44. lubba (Posts: 1311; Member since: 17 Jan 2011)
Unsure about the overall design of the phone. It would have been more beautiful in my opinion as a Phablet with the hump at the upper left corner. The hump would also have been more sleek in a design standpoint as a one piece back cover or plate or unibody. I've read somewhere there is rumor of a 41mpx Phablet slated for end of year. After seeing these leaks, I'm a little disappointed. We'll see if I change my mind after playing with it.
