Nokia 808 PureView

Nokia 808 PureView Following the success of the N8, Nokia has upped the ante by announcing the 808 PureView which boasts a whopping 41-megapixel camera sensor.

Jaw-dropping camera aside, the smartphone's specs are pretty ho-hum. Running on the Symbian Belle OS and powered by a 1.3GHz single-core processor, the 808 has a 4-inch ClearBlack nHD (640 x 360 pixels) display that's protected by Gorilla Glass. The handset also comes with Dolby Digital Plus technology for surround sound on headphones.
The handset's most compelling feature, however, has to be its camera, so that's what we'll be focusing on in this hands-on.

Upside

41 megapixels--that's more than the megapixel count on the full-frame Canon EOS-1DX and Nikon D4 dSLRs...put together.

However, as we all know, sensor size matters as well. The CMOS sensor on the Nokia 808 PureView measures 1/1.2 inches, which is larger than the N8's. In fact, that's larger than the sensors found in most advanced compact digicams such as the Panasonic Lumix LX-5 and Fujifilm FinePix X10. Like other high-end Nokia phones before it, the 808 uses renowned Carl Zeiss-branded optics, which features a molded glass aspherical lens. That's meant to give sharper images with higher contrast and brighter colors.
Combined, the camera is also supposed to perform well in low-light situations with less noise.

The camera app offers three modes: Automatic, scene (i.e., macro, landscape, snow etc.) and creative. Creative allows you more control over the camera's settings, such as white balance, ISO, ND filter and--this is where it gets interesting--sensor mode.
There are two settings you can choose in sensor mode: PureView or full-resolution. PureView allows you to shoot 3-, 5- or 8-megapixel images using Nokia's "pixel overlay" technology. In layman terms, up to seven pixels are oversampled to one pixel in a photo. This is said to produce a sharp image, even when completely zoomed in (viewed at 100 percent).
In full-resolution mode, the 808 is able to shoot in either 16:9 or 4:3 aspect ratio. The 16:9 mode allows you to get a wider 26mm panoramic view, while shooting in 4:3 provides you with a wide-angle 28mm perspective. The former captures photos at 34 megapixels, while the latter hits an amazing 38 megapixels.
The impressive part is, that's still not all there is to the 808's camera. Taking a leaf out of the Sony Xperia S' book, pressing the shutter button allows quick access to the camera app from the lock screen.
In our short time with the demo unit, the camera bootup time definitely takes less than a second, and is probably comparable to the Sony handset.

Another noteworthy feature Nokia has brought to the 808 is a one-finger swipe-to-zoom capability. This is particularly useful in the video mode (the handset is capable of full-HD 1080p recording, by the way), where you swipe upwards on the screen to the required crop factor. Once you lift your finger off the screen, the camera zooms in automatically, eliminating jerky movements that result from manual zoom.
The video recorder is touted to have "high-amplitude audio capture", which is able to record sounds of up to 140dB. You would, for example, be able to shoot a video at a rock concert, without sound distortion.

Downside

There's no denying the impressive specs on the 808's camera, but there are certain areas where it falls short as well. We may be nitpicking, but there's currently no burst mode function. The handset is also unable to capture images during a video recording, which the recently unveiled HTC handsets are capable of.
While the 808's sensor size is indeed large for a smartphone, it's still much smaller than the APS-C format found in most entry-level dSLRs. Even in those enthusiast-oriented cameras, manufacturers tend to avoid going beyond 20 megapixels as that would affect picture quality and low-light performance. This makes us wonder what the point of squeezing so many megapixels on a small sensor is, when most interchangeable lens cameras don't even venture there.
The improved optics has also added bulk to the phone's chassis. Measuring almost 18mm at its thickest point, the 808 is definitely not going to win any awards for slimmest or sexiest smartphone.
Above all, we think that its biggest letdown will potentially boil down to the Symbian operating system (OS) it runs on. Nokia's gradual transitioning to the Windows Phone (WP) OS--plus the fact that the company has yet to announce the next major Symbian update--could cause consumers to think twice about jumping on the OS.

Conclusion

As consumers increasingly rely on smartphones as their go-to camera, Nokia is making a smart play with the 808. In fact, the phone could possibly give compact cameras and dSLRs a run for their money with its larger-than-average sensor, complete suite of imaging features and comparatively lower price. It costs an estimated 450 euros (US$600) and will start to ship in May.
There's a huge "but" though, and that is its Symbian OS. Elop has previously announced that the company will only stay committed to Symbian until 2016.
At a group interview with Singapore media, Nokia's EVP of Sales, Colin Giles, declined to comment on what's next for Symbian after Belle, but stated that innovation on the platform will still continue.
Taking into account the popularity of the Nokia N8--and the fact that many are still using the device--we wonder if the 808 could be just the device to boost the longevity of the OS. We'll reserve that judgement until after we have an in-depth review of the handset.

Nokia 808 PureView Specs Review

Nokia 808 PureView Specs Review

What do we mean here? Well, first of all, the Nokia 808 PureView comes to succeed the N8 – the smartphone that kind of set the new benchmark for camera phones when it came out. Well, interestingly, the still largest handset manufacturer by volume seems to be aiming even higher this time by introducing a handset with a camera which has not 12, not 16... but an enormous 41 megapixels! Sounds pretty wicked, we know.

First of all, we should note that the handset looks like a typical Nokia, which isn't a bad thing, of course. It has a large 4" screen on the front, however, it still has Symbian's usual nHD resolution, which is 360x640 pixels. The display uses the AMOLED technology, and overall it looks cool, despite the relatively low resolution. Touch sensitivity is also pretty good.

Do not expect wonders from this device on the build quality front. Is's actually quite light, and doesn't feel as premium as the N8. Still, it's not bad either.

Design

The obvious drawback to having an enormous camera in a smartphone is that it physically takes up quite a lot of space. That is why the Nokia 808 PureView is pretty bulky by today's standards with a thickness of 14 millimeters. So yeah, sexy is far from the first terms one would use to describe the device. Also, it is definitely among the heaviest of smartphones as it tips the scale at 169 grams. And with that kind of weight, you will definitely be able to feel the 808 PureView in your pocket. Last but not least, its design is okay, yet surprisingly, the smartphone does not feel as that premium of a device as the Nokia N8, as it became evident from our Nokia 808 PureView hands-on review.


Display

With its 4 inches of display real estate, the Nokia 808 PureView hits the sweet spot for many smartphone users. It is neither too big, nor too little, and it is very usable with a single hand. The combination of AMOLED and ClearBlack screen technologies ensures that the display delivers rich colors and deep blacks even when used outdoors on a bright, sunny day. And to make things even better, the display's surface is protected by Gorilla Glass, meaning that it is well armored against every day wear and tear. However, there is something that we cannot overlook, namely that the display on the Nokia 808 PureView has a relatively low for its size resolution of 360 by 640 pixels, which translates into a usable, but unimpressive pixel density of 184 pixels per inch.

Hardware

In terms of hardware, there isn't much that can make the Nokia 808 PureView stand out. Inside it we have a 1.3GHz single-core processor based on ARM11 architecture and backed up by 512 megabytes of RAM. However, that is more than enough to deliver a smooth Nokia Belle experience, so don't worry too much about the smartphone's seemingly underpowered hardware. On-board storage is another thing that should not be much of a concern. You get 16 gigabytes, which is okay for a contemporary smartphone, and if those full-res snaps and HD videos start piling up, you can always expand the handset's storage with a microSD card. Last but not least, we have a 1,400 mAh battery under the device's back cover. It can provide 6.5 hours of talk-time on 3G or about three weeks of stand-by time, which is acceptable by today's norms.


Software

What runs on the 808 PureView is the Nokia Belle platform with Feature Pack 1 enhancements, which is the latest Symbian iteration to date. Thankfully, a lot has been done to its interface, which is why it now looks a lot more like a contemporary mobile platform than it did before. Multiple home screens, variety of widgets, even a drop-down menu reminiscent of that we have on Android – these are the new features that Belle introduced with its release. Besides, it runs noticeably smoother than previous versions as its code has gone through some serious optimizing. For more details, we happen to have a really nice Nokia Belle review.


Connectivity

Connectivity-wise, the Nokia 808 PureView supports everything that is essential for a modern smartphone. For web access there is Wi-Fi b/g/n, and for the times when a hot spot is not around, the 3G HSPA radio can reach peak speeds of up to 14.4Mbps. You also get Bluetooth 3.0, NFC, TV-out via Micro HDMI, and USB mass storage mode for fast and easy file transfer between the smartphone and a PC and vice versa.


Camera

The 41-megapixel camera is what makes the Nokia 808 PureView shine, and it shouldn't be surprising that thanks to it, the smartphone won the Best New Mobile Handset award at Mobile World Congress 2012. We have yet to test it out ourselves, but those Nokia 808 PureView image samples, which are also available in full resolution, look pretty good for a camera phone. Achieving that level of quality is a complicated process, so if you want to learn more about the way the 808 PureView's camera works, we have given it a full-blown overview right here. The camera experience would have not been completed if it wasn't for the xenon flash and LED light helping out in low-light situations. And when it comes to video, the handset can capture footage at 1080p resolution. 

Expectations

The Nokia 808 PureView may be pretty average as a smartphone, but as a camera phone, there doesn't seem to be anything else on the market that can beat it. Still, whether that is 100% accurate will become clear once we get our hands on a final unit and put it through its paces. The smartphone is expected to become available in May and will retail for about $600 off-contract.
