The Nokia N8 marks the introduction of the
revamped Symbian operating system (OS) now known as Symbiam^3. The
Symbian OS has been seen to be lagging behind the newer OSs
especially in terms of its user interface (UI) and so the update was
much need.
The N8 is presented
in a very solid aluminium body with a toughened 3.5" AMOLED touch screen.
It is a sleek design with only a menu button presented below the
screen with no physical call/end buttons. By doing this Nokia
emphasise the fact that this device is more than just a phone.
The volume
control, lock switch, and camera shutter button on one side of the
N8 and there are ports for the sim card and micro SD cards, as well
as a micro USB port for data transfer and charging the unit on the
opposite side.
Are is also the proprietary Nokia charge socket on the base of the
N8. The top of the N8 has the power key, headphone and HDMI sockets.
The primary feature of the N8 is its camera
which offers 12 mega pixels and 720p HD video capture. Instead of
using the typical cameraphone sensor size of 1/6" the N8 has a
larger 1/1.183" sensor.
The Sony Ericsson Satio has a similar 12
megapixel but with a smaller sensor.

The Nokia N8 is a feature rich smartphone but
this review will concentrates on the phones photographic
capabilities.
Features
The key features of the Nokia N8 are:
12 megapixel resolution on 1/1.183" large
image sensor
Focus aid light and Xexon Flash
5.9mm f/2.8 Carl Zeiss Optics (28mm
equivalent in 35mm format)
Face Detection
Image Geotagging
720p @ 25fps in H.264 or MPEG-4
Ambient stereo audio recording
3.5" AMOLED Capacitive Touch Screen with
640x360 (16:9 nHD) resolution and 16.7 million colours.
With the N8 unlocked it is just a simple
matter pressing the dedicated camera shutter release to active the
phones camera. The camera starts up quickly with the onscreen
display icons showing the shooting mode (stills or video), flash
mode, settings, options, digital zoom and onscreen shutter release.
By pressing the Settings icon the following
are revealed:
Scene mode
Face detection
Grid (grid overlay)
Self-timer (off, 2, 10 and 20 seconds)
Colour tone (normal, sepia, black &
white, and vivid)
White balance (auto, sunny, cloudy,
incandescent, fluorescent)
Exposure compensation
ISO sensitivity (low, medium, and high)
Contrast
Sharpness (hard, normal and soft)
Photos (Photo gallery - stills and video)
Pressing Options reveals submenus for the
following:
Secondary (front facing) camera
Settings (adjustment of image size, GPS
tagging, image review, image naming, shutter sound, auto rotate
images, and restore camera settings.
Video mode
Go to Photo gallery
In the sub-menus Image Quality actually refers
to the image size rather than referring to adjustment of JPEG
compression levels. The image sizes provided are:
Large - 12mp, 4:3 aspect
Large - 9mp, 16:9 aspect
Medium - 3mp, 4:3 aspect
Small - 1.3mp, 4:3 aspect
Small - 0.3mp, 4:3 aspect
Surprisingly the most common aspect ratio of
3:2 is not represented. On the Sony Ericsson Satio 3:2 aspect
related to 10mp resolution. There is no provision for adjustment of the JPEG
image compression levels.
The autofocus is centralised with no provision
for touch focus on any location on the screen.
When it comes to video there is no autofocus
but the focus is set to produce sharp results from beyond 60cm.
The options provided are more limited in the
video mode. For the Scene mode:
Automatic
Low light (for indoor filming)
Night (for filming in very dark
conditions)
Under Options the video settings offer:
Video quality (High Definiion, TV high
quality, and Sharing quality)
Geotagging (on/off)
Image stabilisation (on/off)
Audio recording (on/off)
Video review (on/off)

Performance
The Nokia N8's camera was easily
activated and ready to start shooting just by pressing the shutter
release. With the
autofocus area fixed in the centre it was necessary to rely on half
pressing the shutter and then recomposing the scene to ensure the
right part of the scene was in focus. The exception to this was when
face detection was active which would detect faces in any location
on the screen. The N8 had no touch focus feature. Such a feature has
value and would come in useful if the phone was (somehow) mounted on
a tripod and an off centre object was to be focused on. There were
times this feature was missed but the centralised AF was efficient
in operation and rarely gave cause for concern.
Image Formats
The N8's image sensor has a
native aspect ratio of 4:3 and only at this aspect is the full 12
megapixel resolution realised. The wider aspect of 16:9 (which fills
the N8's screen) seemed to be more suited to
landscapes and scenic views. The most popular 3:2 aspect ratio was
missed as it would of been the preferred aspect to shoot the test
photos with.
4:3 Format - 4000 x 3000 pixels
16:9 Format - 4000 x 2248
pixels
Image Sharpness
The combination of the larger
than standard 12 megapixel sensor, Carl Zeiss Tessar optics and
respectable image processing have produced images with a great
amount of detail with nice gradations in the colours. The colour
rendering appeared to be quite neutral. This combined with the fact
that the autofocus system very well meant that photos could be
produced that would look respectable on an A3 print. Considering
that on the whole the majority of prints people make are no larger
than A4 then the photos derived from the N8 will impress many.
f/2.7 @ 160 sec, ISO 105
Centre area - 100% crop
Left area - 100% crop Image is a little softer in the corner but still acceptable.
Centre area - 100% crop Plenty of detail is shown as well as good contrast. The image has
not been overly sharpened.
Left edge - 100% crop Detail has become soft and there is noise in the shadows.
Right edge - 100% crop Detail has become indistinct.
Exposure modes
The only form of exposure
adjustment was via exposure compensation. Unfortunately, the user
interface made it awkward to use and when implemented there was no
indication of it being active when back to the main screen. The
aperture being fixed at f/2.8 meant that correct exposure was
determined by the automatic setting of the shutter speed. Examining the photos taken during tests
showed the shutter speeds ranged from 1/8 sec to 1/640 seconds. These figures will be
revised when weather conditions improve here in the UK.
The auto ISO
seemed to adjust the ISO sensitivity across the whole range from ISO
100 to ISO 800. Manual adjustment of ISO offered only setting of
100, 400 and 800 which although not comprehensive was very practical.
Flash Photography
The xenon was did its job well
considering its size. Its power output was limited and so offered
less of a flash range than a digital compact camera but it had
sufficient power to illuminate the typical people portrait shots.
Xenon flash lit subject
Face Detection
The face detection mode was active
by default and was able to detect several faces at a time quickly.
The face that is determined as the point of focus and exposure has a
yellow border with other faces surrounded by white borders. Face detection
removed
(or at the very least) reduced the need to focus and re-compose
should the subject be located off centre.

Low Light Photography and
Image Stabilisation
The Nokia N8 lacks image
stabilisation when shooting stills. With its shutter speed capable
of dropping down to 1/8 second it can be difficult to get a steady
shot. Image sharpness reduces as the ISO sensitivity increases.
f/2.7 @ 1/8 sec, ISO 524
Centre area - 100% crop
Right edge - 100% crop The effects of noise reduction is evident with low noise at the
expense of image detail and sharpness. Note the water paint effect.
Left edge - 100% crop
Centre area - 100% crop The detail in the trees branches is almost lost against the night
sky.
Centre area - 100% crop High lights are totally blown out.
Provided a steady shot can be
obtained the high ISO images are usable as long as it is not
required to print full size or heavily crop.
Geo-tagging
Photos were able to be taken with
their location embedded
in the photos exif file when the geo-tagging feature was activated.
An icon appears when it was activated and indicated the status of the
GPS. As is usually the case with GPS, when it is initially powered
up it takes time to establish the location accurately but after that
detection was very prompt.
Panoramas
The Nokia N8 does not have a built
in panorama mode but via Nokia's Ovi Store Nokia provides an app
that performed this task. The was provided free of charge and worked
reasonably well but at times lost track of the N8's position as it
was panned. In comparison to that in the Sony Ericsson Satio
it did not seem as reliable but then it was not limited to stitching
together one three shots.
High Definition Video
The video mode produced
impressive results. The results looked detailed no doubt aided by
the N8 allowing bitrates up to 12Mps. As with the stills images
colour rendering was on the neutral side. This would be of benefit
for those who wish to post process their video images. The cameras
lens in video mode was set to provide sharp focus from 60cm to
infinite but in practice the minimum focus distance seem more like
90cm or a meter. The autofocusing was missed but the fixed focus
ensured that there was no problems with focus hunting (which can
happen when an autofocus loses track) or the need to refocus. The N8
was not suitable to do macro shots in video mode which makes filming
subjects likes insects out of the question. One possible mitigation
for this was to use the digital zoom. It provided x3 magnification
without apparently degrading the image.
The N8's two microphones didn't produce the typical
stereo left/right field due to their unusual placement at the front and back of the N8.
Certainly the microphone on the back had its sound panned towards
the right side which helps to separate any narration. The two mics
showed good sensitivity and an extended frequency response which
helped to produced a full bodied sound track. The 128kbps bit rate
for the sound track was put to good use. On a few occasions low
level clicking sounds could be heard. The cause of it was not clear
but it may of been due to other tasks being performed in the
background.
The Nokia N8 Short Movie
Shown below is a short movie
called The Commuter which was filmed using the N8, directed by the
McHenry Brothers and features Pamela Anderson, Ed Westwick, Dev
Patel and Charles Dance.
The Travel Companion
The N8 looks set to be a worthy travel
companion. It's multimedia credentials would keep a traveller
entertained especially with a 32GB microSD card in the phone to
boost the already sizable 16GB internal storage.
The built in RDS radio
was well designed and delivered clear and stable reception.
The phone can play back movies in the MPEG4
and H.264 format movies which it's AMOLED 16:9 screen is very suited
to producing a very colourful and detailed display.
The music player worked well and provided
impressive audio via the supplied ear bugs. Any headphone can be
plugged into the 3.5mm jack but it's worth noting that if the
headphone impedance is not correct the sound could be degraded. For
example the usually great sounding Sennheiser PX100 headphones
suffered a bit at the high frequency end of the audio spectrum. The
provided headphones also have the advantage that it has a controller
for adjusting volume, and transport controls to aid finding the
required track or moving to a different point in a movie.
Apart from keeping the traveller entertained
the Nokia N8 has Ovi Maps. The maps makes it possible to plan
destinations on a computer that is to be visited and then have the
maps downloaded to the N8. This ensures that roaming data charges
are avoided whilst overseas. Other locations can be visited can be
recorded on the maps as way points but its not possible to add
accompanying notes. The added waypoints can be shared (exported) via
email or sms but the format is not suitable for viewing the waypoint
on Google Earth. What is produced is a link to the online Ovi maps
which will show the area surrounding the waypoint. This is handy for
showing friends and family back home your current location. If there
is the need to document a journey then an application like Trip
Journal does this very well. Unfortunately it is not yet available
for the N8.
Speaking of apps, they can be obtained from
the Ovi Store. It's a growing collection of apps although some apps
are only provided direct from the developers website like in the
case of Skype.
When travelling a decent web browser is always
useful. In these days of extreme weather events and flight delays
being able to check the news, weather reports or alternative flight
details is always handy. The N8's web browser does well at rendering
pages but its interface is not user friendly and it will struggle to
handle large web pages.
Emails accounts were straightforward to set up
due to the built in email wizard. For the likes of Yahoo, Google,
and Hotmail the emails are going via Nokia's own servers. This had
the advantage that emails are straightaway set to the phone. The
disadvantage is that there seems to be a 4MB limit on emails being
sent out. Email accounts can be set up manually but then the phone
has to actively fetch at intervals that can be defined.
The SMS worked well and could form the
messages into conversations.
The phone function should not be be forgotten
and it felt strange to be using a Nokia phone without the physical
call and end keys. The result was the reliance on touch screen to
initiate and end calls. Making calls was simple enough but strangely
ending calls was initially confusing if the dialler was on the
screen. With the dialler displayed there was no provision for
directly ending a call. In order to end a call it would be necessary
to press the Back or the Green phone icon to get back to main call
screen where the end call button can found.
For the traveller a useful application was
Notes. The keyboard provided came in two forms. When the phone was
in portrait orientation the typical T9 keyboard was presented and in
landscape it became a qwerty keyboard. There was no option to have a
portrait qwerty keyboard.
Whilst travelling a useful addition to the N8
is to have a battery pack on hand. The N8's internal battery is the
BL-4D but it is sealed in the body. This means carrying a spare
battery is not an option. What can be done is to carry an external
battery pack. Nokia's Extra Power DC-11 is one such device but there
are other such packs designed to plug into the micro USB socket like
the Energiser XP2000 (2000mAh), Dexin BluePack S8 (3000mAh), and
range of other products on the market.
Compared with the Sony Ericsson Satio
The Sony Ericsson Satio, which was introduced
a year earlier than the Nokia N8 is perhaps the closest to the N8 in
terms of its key feature set. The Satios key feature is the camera
which sports a 12 megapixel sensor. Video capture is only at WVGA
(around 800 x 480 pixels) resolution. The N8 offers a better all
round feature set but there are areas that the Satio still does shine. The
Satio was designed with its camera in mind
and this is reflected in its controls. There are physical keys
provided to quickly change from stills to
video and back again. There is also a key that brings up the photo
gallery so it's not necessary to dig into the menus to get to the
photos. The lens shutter protects the lens as well as providing a
method to quickly activate the camera.
Both cameraphones sports screens with a
resolution of 640 x 360 pixels but the technology they use is very
different. Both screens are fine under indoor or subdued lighting
but outside in bright conditions the N8's AMOLED capacitve touch
screen remains easy to read where the Satio's resistive touch screen
struggles.
Where the Satio scores over the N8 is its
camera user interface. The N8 has the better and newer operating
system but the Satio's camera UI makes getting at the features
straightforward. Its a matter of touching the required icon and
selecting the mode. The N8 on the other hand required too many key
presses to get to the required feature and then get back to the
shooting screen. Also, the arrangement of the features did not
seem very logical in some instances. No doubt over time the user
would get use to the UI but it is a deterrent to making full use of
the cameras feature set. Hopefully this is something that will be
refined in future firmware updates.
The N8's photo gallery offers a lot of
flexibility as it allows photos and videos to be tagged or placed
into albums. The Satio doesn't have such features but its gallery is
very intuitive to use and auto collates the images into groups based
on the month the photos were taken. The N8 will indicate the month
only if the scroll bar is used when browsing the gallery.
An ace feature for the N8 is 'USB on the Go'.
The ability to connect a USB memory (via the supplied cable) direct
to the phone and access its contents or transfer media to it. This
feature worked well with USB memory sticks but did not work
with a portable hard drive like the Western Digital My Passport
unit.
The physical call keys on the Satio made it feel
more of a phone where as on the N8 the phone aspect felt to be
relegated to just another feature. However, both phones have good comms and call quality never seemed to be an issue.
The N8 offers the better all round image
quality especially in terms of lower noise and detail. The Satio
seems to of squeezed every drop of detail out of its tiny image
sensor but its images can look a little flat compared to those from
the N8. The
N8's photos seem to have more body which may be an indication of the
Carl Zeiss lens offering better contrast as well as the benefits of
having a larger sensor.
The N8 uses electronic image stabilisation for
video capture and unlike the Satio gives the choice to activate it
or not. Shooting without it allows the full 28mm view to be used
where as with it active the view is reduced. Strangely there is no
IS implementation when taking photos. Certainly the benefits of
electronic IS is very limited (especially compared to optical IS)
but on the Satio what little difference IS has made often made the
differences between having an unusable photo and one acceptable
sharp in low light conditions. The higher maximum ISO of the N8
(800 compared to 500) helps.
When it comes to video capture the N8 wins
hands down. The Satio does a good job with its WVGA resolution but
it cannot compete against 720p resolution. Also, the N8 renders the
colours a lot better. The audio track is also fuller as a wider
frequency range is captured.
The Satio has the more flexible AF system with
the inclusion touch focus but the N8 focuses faster and more
consistently under low light conditions. The Satio unfortunately
disengages its focus aid light when its xenon flash is switched off
but N8 does not do this ensuring the focus aid light is always at
hand.
Currently the Sony Ericsson Satio provides
better facilities for uploading photos to social networking sites
like Facebook. For the N8 rather than using the Facebook app the app
called Gravity is the better choice.

The Nokia N8 with its large sensor and Carl Zeiss lens produces images
to be proud of. As the phone is the device most people have with
them at all times the N8 may see a lot of use whether that be
shooting stills or videos. The N8's image quality helps to show that
a cameraphone need not be limited to taking mediocre quality images
that are only suitable for viewing on small screens.
The first N8 sample user for this review
unfortunately developed a fault were the phone would ramdomly
restart itself making use very difficult. The second sample worked
flawlessly. The phone has a lot more features than was covered
here such as the FM transmitter, the three home screens with
widgets, media editing applications, file manager, and music player
to name but a few.
The user interface is were the N8 could do
better. Symbian^3 is an improvement on Symbian S60 5th edition but
it does not have the finesse and speed of the likes of iOS and
Android. The OS is quite capable and has helped to make the N8
feature rich but it could do with an extra bit of polish. The scroll
bars remain from older Symbian versions remain but they are not
essential for scrolling now. When they are used they tend to act as
a kind of index.
The trend now is not to have protective
shutters on cameraphone lenses now and the N8 has followed that
trend. Unfortunately it was just too easily to get finger prints on
the lens leading to degraded images making it important to check the
lens before taking important photos.
The web browser was the biggest
disappointment. It does a great job of rendering pages and its
ability to show Flash was a nice bonus but its user interface is
unfriendly and it struggles to handle large or graphics heavy
webpages.
Despite the negatives, the Nokia N8 was a much
liked and useful product. Its photographic and audio capabilities
will ensure that it would make a useful travel companion. The
quality hardware gives Nokia a solid base from where to continuing
building and hopefully continue bringing updates and improvements.
