    Nokia 808 PureView 41 megapixel camera phone First Impression

    Nokia has obviously planned to revolutionize the world of camera smartphones . And they achieved it with the launch of new Nokia 808 PureView at MWC in Barcelona. The most revolutionary feature of this device is its 41 MegaPixel Camera with Carl Zeiss lens. Not even digital SLR cameras in the upper class can come up with such values. Current smart phones with cameras make very good present for up to 8 megapixels with it, enough is known completely.

    Nokia PureView 808 runs on New Symbian Belle OS and packed with 1.3 gigahertz single-core processor, four-inch touchscreen with a resolution of 360x640 pixels. In addition there is 512 MB RAM with inbuilt 16GB storage capacity and expandable. It also features micro-USB and micro HDMI sockets. Furthermore, USB On-The-Go, DLNA, Bluetooth 3.0 and an FM transmitter on board.

    The smartphone is able to save the photos as compact files, making it easier for sending e-mail and more. Video recording is available in full HD resolution. There is onboard sound recorder that records in Dolby CD-quality and a special technique, the surround sound is to perform tricks up all over headphones.

    The use of a 41-megapixel sensor is not so crazy as it sounds at first. The sensor is considerably larger than other mobile phones, surpassing even the most compact cameras. The phone uses the high resolution in order to create a high quality 8-megapixel image, or provide a zoom, which effectively makes the photo just different from others. While other mobile phones access to a digital zoom, which is always associated with loss of quality.

    Apart from the camera and lenses, processing and haptics worked well, the speed of the user interface could in most cases are equally impressive. Only the detection of finger entries appeared at one point or another not to work reliably, perhaps because of a not yet fully completed customization of the software.

    For image quality, the lens could also contribute. The Carl Zeiss lens offers a maximum aperture of F2, 4 Along with a real focal length of 8.02 millimeters, which corresponds to 26 millimeters in small picture equivalent, which should at least allow for close-up some creative depth of field shenanigans. After the sharp small area with the larger sensor, but also the demands on the auto focus - because at a shallower depth of field you can afford fewer mistakes. A real iris diaphragm that could increase the depth, there with the camera, appears not to also. After all, to reduce the amount of incident light is a neutral density filter on board.

    The intensity of F2, 4 should be important in practice to keep the shutter speeds as low as possible. For the high resolution shaky hands forgives nor Mayo marks on the lens. At least not if you want to enlarge the images still strong. A real optical or mechanical image stabilizer seems to Nokia mobile phones have certainly not missed.

    Another disadvantage is the combination of large image sensor and a small lens of the lack of macro mode. The minimum focusing distance of the camera is 15 centimeters. Closer you get to the wide-angle does not approach the subject. Lots of light and steady hands required, should the high resolution of the sensor support here but still many details to be orderly days. Otherwise, help the xenon flash of the Nokia 808 but certainly also further - according to the manufacturer, the range is 3.5 meters. For motion pictures is the way in addition a video LED integrated.

    To keep the cost in spite of the elaborate camera within limits, it is at the 808 next to the spectacular view Pure notches largely standard fare. The display is 4.0 inches tall and resolves to 640 by 360 pixels. For processing power provided by a faster 1.3 GHz single core processor. There are also 16 GB internal memory that can be expanded via microSD card up to 32GB. As a Symbian operating system is used. Who is not happy: Nokia plans to various reports , according to bring the Pure View technology on Windows phones. Android and iPhone fans look good at first but in the cold.
