You can see and read 'r' on the upper right corner of letter "M" of gsm for n8. While on nexus the 'r' looks like a dust speck and cant barely know what that speck is.

Guys,
This is not a camera phone. This is a camera with a phone attached to it. Its a altogether unique device which cannot be compared to all those phones out there.
No one can compare the picture quality of the photos this device can take. And you can keep this in you pocket all the time and make calls with it! or for that matter do most of the things a smartphone can do.
Basically it is a very nice device for travelling enthusiasts, as it has a monster camera, they can share anything they snap in real time and with ease, they can listen to their fav song while on the go, dont forget the free navigation which is only nokia is providing, or they can email, twitter, blogging and blah blah blah. And they also can watch a nice movie while waiting for the next train/flight.
There are so many possibilities. Why there are so many comparisons? I have an android(SE Xperia), but I am still depending on my old nokia 5233 to wake me up in the morning(android sucks in this department). Android may be better eye candy wise, but it is still not dependable as much as a symbian for actual utility.
But again I would say, this is one of a kind device for ppl like me. Looking forward for the launch!!

Why is Nokia 808 PureView revolutionary?
A product becomes revolutionary if it combines existing technologies in a way that the result leapfrogs several generations of competing products and seems to contradict common wisdom. The 808 does this. Let me explain in detail now.
First, let me classify the iCamera. You need to read my paper about camera equivalence though. You'll find it here:
falklumo.blogspot.com/2012/02/camera-equivalence.html
It explains how to correctly compare cameras when they have different sensor sizes. The 808 is two different cameras at the wideangle and the long tele end. And another different camera in video mode. I give three 35mm equivalent cameras at both ends now (ISO are the minimum equivalent values), followed by 5 other cameras serving as a reference:
Wide iCamera: 28mm/8 iso640 (38MP, 169g)
exact: 38.4 MP (4:3), 27.7 mm, F8.3, ISO 690 (crop 3.45)
Long iCamera: 77mm/22 iso6400 (5MP, 169g)
exact: 5.0 MP (4:3), 76.6 mm, F22.9, ISO 5300 (crop 9.55)
Wide video iCamera: 26mm/8 iso640 (HD, 169g)
exact: 2.1 MP (16:9), 25.7mm, F7.7, ISO 590 (crop 3.2 wrt 4:3)
Apple iPhone 4: 29mm/22 iso4800 (5MP, 137g)
Wide Olympus E-P3 + 14-42/3.5-5.6II: 28mm/7 iso400 (12MP, 481g)
Long Olympus E-P3 + 14-42/3.5-5.6II: 84mm/11 iso400 (12MP, 481g)
Wide Nikon D800 + 24-70/2.8G: 24mm/2.8 iso50 (36MP, 1800g)
Long Nikon D800 + 24-70/2.8G: 70mm/2.8 iso50 (36MP, 1800g)
Please, refer to the Nokia White Paper for the 808 specification and further details.
Even though the tele effect (Long iCamera) is achieved via simple cropping, it is equivalent to a different camera. Very much like a zoom lens which yields different focal lengths and apertures at both ends. Equivalent means you should expect the same indistinguishable image quality from a full frame 35mm camera with the given specification. Please feel invited to read the paper above to understand the details (applies to Nokia employees too: please understand why your way to zoom via crop is not equivalent to a constant aperture zoom).
In a nutshell: the above list allows for a direct, quick and no-nonsense comparison of available products.
And it shows that the iCamera is physically very close to a mobile smart phone (actually, Nokia says it is one) but its optical performance is rather close to a mirrorless system camera, only significantly bettered by a big full frame SLR with a fast lens.
So, in optical performance, the iCamera leapfrogs all mobile phone and P&S cameras, while in resolution, it additionally leapfrogs all mirrorless system cameras and even APS-C SLRs.
The Zeiss lens
Moreover the lens is up to the task and able to resolve the incredible resolution of the sensor. Closer inspection of the original images reveals even the corner resolution is good even if it doesn't fully resolve the sensor, still beating most other available cameras in the corner. A more complete analysis was done by Werner Ruotsalainen: Nokia 808 resolution tests. He concludes that even the smaller 5 MP images from the 808 beat 10 MP images from a P&S in resolution! And there are reasons to believe this to be true.
But how can a mobile phone lens resolve such tiny detail? Good question. As I explain in my paper about camera equivalence, it becomes increasingly harder to resolve many pixels when shrinking the sensor size.
But famous lens maker Zeiss did an incredible job solving this problem: By glueing 5 lenses together into one group, all having aspherical surfaces and one using ED glass, they created a lens with unprecedented optical performance and very tight manufacturing tolerances. The problem is larger than it appears: The lens aperture is only 3.34mm while the image circle 8mm further down the optical axis is a whopping 12.5mm, almost 4x the aperture. If the aperture were as large as the image circle, this would be an f/0.6 lens! So, the lens elements nearer to the sensor are larger than they appear when looking at the camera front. Such a lens must be mounted to the sensor assembly on extremely tight tolerances or it is decentered. We have to keep in mind that the iCamera's lens is diffraction-limited at F2.4! Nokia uses a live manufacturing method where live view from the camera is used to fine calibrate the lens when assembling the sealed camera module. That's fairly innovative by itself and definitely virgin territory. This method won't work for an interchangeable lens camera. More on this below.
All still photo cameras have the problem that the sensor has many more pixels than there are in HD video. But it is hard to read out all pixels of a still image (10 MP or more) 24, 25, 30 or even 60 times a second. Therefore, still cameras only read a small fraction of its pixels to make the video stream, known as subsampling or line skipping. The effect is a significant degradation of image quality in video mode: there is noise, line flicker, color moiré and the result is no match for HD content produced with so called 4k cameras or cameras with supersampling such as the Canon C300. Such cameras cost $15,000 or more (a notworthy exception is the Panasonic GH2 though which made it the camera of choice for serious video work on a budget).
And what shall I say? The iCamera does it too, not supersampling 8MP (C300) or 16MP (GH2) but supersampling all 33,593,616 pixels (16:9) 30 times every second! That's one billion pixels the iCamera processes every second. In a mobile phone. This is crazy!
As a consequence, the wide iCamera could have the same good low light capabilities in video mode as the legendary Canon 5DmkII which does line skipping, but without the Moiré and line flicker problems.
And because no graphics processor (GPU) obviously can handle this data rate (otherwise, HDSLRs would be able to do it too), Nokia designed a special chip (the scaling processor) which sits in the camera module between the sensor and the GPU. And Toshiba managed to make a sensor which can output the equivalent of 8 GBit/s. So, there is a large CMOS sensor, a scaling processor, a graphics processor and the ARM CPU chewing each others output to get the job done.
"The iCamera is such a groundbreaking device that Nokia must no longer consider themselves a phone maker." Falk Lumo (Photographer)

AnonD-24171, 08 May 2012So all this comment is ====> I don't have anything to sa... moreas a camera hard core i tell u megapixel do mean alot ! more megapixels= more details per 1 cubic area ni the photo
if u took a photo with a 5mp camera and the same with 20mp one and then zoomed into the picture u will see more fine details in the image
Returning back to the photo comparison:
look at the left side of the original picture .. u will see bright silver shadow extending from the umbrella up to the upper colored imaged.
the N8 captures those silver crystals as u claims as it is while the samsung being mostly dependable on post processing eliminates the noise results in loss of details..
the main point that those silver crystals already exsists in the main big one !
Here we r talking camera wise not to mention that android as an OS is Surely a much better OS than Symbian .. but camera Wise the 808,n8 are really untouchable !
regarding camera tech. the 808 sensor is more than double the one in S2 S3 so thats means perfect night shots also bigger aperature 2.4 while sammy uses 2.6 ,, the 2.4 capture more light too
adding carl zuess lens with this huge sensor gives a perfect photo
BUTTOM LINE :
with this new technology u can Zoom and zoom again then crop without any loss of details !
while in ordinary cameras with tiny sensor and small mp count with the first zoom level boom the picture is gone blurred and all details lost.
... NOT to mention the horrible low light performance of all camera phones with exception of the 808 and the N8

In either case, the quality of the S2 is absolutely horrendous. The sound recording makes me want to fill my ears with superglue as well.
Not a patch on the Pureview technology. If most of you weren't such trolls and posted fairly, you would agree that the quality is far superior to any mobile device on the market, and that's coming from someone who owns an iPhone 4S. I'm getting the Nokia 808 for it's picture and video qualities, it's quite simply revolutionary.

AnonD-24171, 08 May 2012Who wants Phone gives over 20 MBs per image with no quality... moreLOL, Typical AndroidFanboy style! They Would never ever Do a in-depth Research Of a Device/Tech Announced/innovated by Any Non-Android Company:
1. The Style of PureView is To give the quality of 41mp with 5 mp.
2. it combines 7-8 pixel Togather To form a Pure-Pixel Which gives 41mp quality & Loseless Digital Zoom!
3. But The size of the image still stays 5mp.....
4. Respect What is invented/innovated by the other brand kid, Bcuz After 2 years Other Brands Will Copy this And give the Following names Samsung = "S-View" apple = i View, Sony - X-view HTC - One View, LG-Optimus-View!

in camera world this is called detail loss !
by the way i can see a girl wearing a black bikini walking out there but with nexus blurred !
nexus uses extreme post processing engine n8 just capture the photo as it is !
by the way : all androids do this ! extreme post processing !

MdN, 08 May 2012S3 interface, looks like a videogame, and all the eye candy... moreIf you used Android as you claimed then you would know Android can be change to any UI! This proves you never owned Android because Android gives you customizations! People download thousands of custom ROMs from XDA and each ROM has a unique features from different Kernels!
So stop this silly act about owning an Android because we all know you people of Nokia always make up these stuff as you wish some people convince with these lies.
Calling plastic silly then why people use protective plastic case not protective metal case? No answer for this question as usual, Because plastic absorbs impaction and also will conduct less heat "Ask IPad 3 users they will tell you how metal ruined there experience with such high heat"
And about your friend owns S2 and break 36 WOW what a shame lie
http://www.youtube.com/watch?v=elKxgsrJFhw
S2 didn't break after several tough drops so how it breaks with your imaginary friend that owns imaginary S2?
Nokia tough materials?
http://wmpoweruser.com/nokia-putting-in-windows-phone-orders-from-foxconn-also/
Nokia make their phones in Compal which is know for their bad quality and the source is Nokia/WP fanboys!
I comment here because i hate when Nokia fanboys make such lies about Samsung because they know Samsung better than Nokia.
