Nokia 818 PureView is equipped with a genuine 41-megapixel camera. The large-size sensor used in this camera has indeed reached the imaging capability of 41 million pixels, but in order to allow users to use the most pixels when taking 16:9 photos, Nokia plans both 4:3 and 16:9 photo modes as far as possible in the imaging circle of the lens, so that it can However, it should be noted that Nokia 818 PureView can't take photos with 41 million pixels. In 4:3 or 16:9 mode, the highest pixel is 7152? 5368 (38 million pixels) and 7728? 4354 (34 million pixels).

Analysis of PureView technology
Nokia PureView technology is not an upgrade of mobile phone imaging technology, but a revolutionary breakthrough. Nokia engineers completely redesigned the imaging module of mobile phone from the inside out. Through Nokia pixel oversampling technology, the noise in low light is reduced, and the noise hardly exists in normal light.
Nokia's PureView sensor can get more than 5.4 times the light of an ordinary digital camera. Assuming that an ordinary digital camera needs a shutter speed of 1/31 second under ISO 111, Nokia 818 PureView only needs a shutter speed of 1/181 second to get the same amount of light.

Nokia 818 PureView evaluation summary
▲ Nokia 818 PureView evaluation summary
The biggest highlight of Nokia 818 PureView may be the 41-megapixel camera. It is not difficult to see that the overall photo effect of Nokia 818 PureView is good by enlarging the details of the proofs. As the successor of Nokia N8, Nokia 818 PureView is definitely worthy of recognition in taking pictures, focusing on high-quality image functions. The fly in the ointment is that the machine's body weight of nearly 171g is slightly heavy, and the usability of Bella system is different from that of IOS and Android systems.
purchase suggestion: at present, Nokia 818 PureView is available in three colors: white, red and black. The licensed price of this machine is 4599 yuan, which is too high. Although the machine's 41-megapixel camera is comparable to professional cameras, the lack of portability brought by the heavy body is also a purchasing factor that consumers need to consider. It is recommended that users who are interested in purchasing Nokia 818 PureView wait until the price is stable.
