Nokia 7 Reviews: Zeiss knife not old |

If you close your eyes now and think about the Nokia brand, what would you think of? Saipan, smashing walnuts or WP, polycarbonate? But think about these keywords are a few years ago, Nokia's landmark element , So what can we think of today's Nokia? Today we come together to experience the latest flagship of Nokia - Nokia 7, to see what it can give us the impression.

Configuration, the Nokia 7 equipped with a Qualcomm Snapdragon 630 processor, GPU image processing capabilities than the previous generation to enhance more than 25%. Has 4GB + 64GB and 6GB + 64GB memory combination of two pre-installed Andrews 7.0 system, battery Capacity of 3000mAh, support dual SIM dual standby full Netcom.Photo, Nokia 7 equipped with a 16 million pixel Carl Zeiss certified camera, front camera for 5 million pixels.

Nokia has always been the most proud of its industrial design capabilities, whether it is the Saipan era of a variety of 'subversive three' cool models, or the era of WP plastic to play tricks to polycarbonate, Nokia In the serious homogenization of the mobile phone market can stand out .However, I am sorry Nokia 7 did not see the kind of revolutionary mobile phone design elements.

Appearance, the Nokia 7 has black and white color, while the overall fuselage nowadays the mainstream of the double-sided glass + metal box 'sandwich structure'.

Nokia 7Positive coverage of a 2.5D Corning third generation gorilla glass, The screen is a 5.2-inch LCD screen, followed by the distribution of the front camera, handset, distance sensor and the Nokia brand logo.

Back of the fuselage is a hyperbolic arc glass, fit with one hand when holding the palm of your hand, feel comfortable.Here the back of a protruding camera, The 'ZEISS' logo on this logo represents the Carl Zeiss certified camera, Although Nokia did not follow the mainstream with dual cameras, but Carl Zeiss certification is still a lot of ability to take pictures of this phone a lot, while the camera just below, there is a silver edge of the circular fingerprint recognition area, the back of the central location Printed with Nokia brand logo.

Nokia 7 fuselage in the middle of the frame with 7000 series aluminum frame, compared to 6000 series aluminum material durability better, and the fuselage left and right borders with the hyperboloid of the rear shell also has the corresponding curvature of the contraction, one hand holding Feel excellent.

The top of the fuselage has a 3.5mm headphone jack, body Left side Have a SIM card slot, Right From top to bottom in order to distribute the volume keys and power button.The bottom of the fuselage for the speaker and Type-C interface.

Overall, the Nokia 7 industrial design overall does not look out of color, think of the past two years, the popular cell phone ring full screen, dual camera and other design elements, Nokia 7 even outdated. Maybe 'back to the blood' takes time and look forward to Nokia Re-lead the trend of mobile phone design that day.

The above is about Nokia 7 product evaluation reports, the Nokia 7 appearance, screen, camera, battery life, performance and other follow-up content, please continue to focus on Zhongguancun Online Nokia 7 evaluation report.

Nokia 7 uses a 5.2-inch, resolution of 1080P, 424PPI screen, whether the overall brightness or detail of the fine can be satisfactory, the following we BM-7A through the actual test.

The data show that the maximum average brightness of Nokia 7 screen 536nits, the basic daily use of outdoor no problem; color temperature 7300, although some of the data on the cold, but I use these two days down, even if the phone at night no significant discomfort; Domain is quite satisfactory, 83%.

In short, the LCD screen used by Nokia, whether it is used under outdoor glare, or watch for a long time under normal circumstances can make the user 'pleasing.'

The essence of the photo is inseparable from several dimensions, such as resolving power, color orientation, white balance, tolerance and so on. Therefore, our evaluation standard starts the standard photographing environment and sets up a dataized photographing template. At the same time, Imatest software quantifies the experimental data and finally obtains Truly credible evaluation results.

The next shading test was based on the actual shading in a standard light source D65 environment and the actual performance of the commercially available model was scored for the type tested by Imatest's objective comparison.Imatest is a pretty good digital imaging test software covering SFR, color, noise, and also for full testing of printers, scanners, etc. The system is based on Matalab, a well-known math computing platform with high reliability and very deep drawing content. Here we use Imatest and 24 color standard colors Card and grayscale test chart to quantify the color reproduction, white balance and dynamic range of the test shots.

1, resolution

Resolution refers to the ability to distinguish the details of the original photographed, the better the resolution of the control of the details of the better, the more natural part of the screen transitions. There are many ways to test resolution, here we choose linear test mode, it The advantage is very intuitive, with the naked eye can be observed, we intercept part of the test sample position as a test area, test the resolution of the Nokia 7 camera.

2, white balance

White balance is an indicator of the whiteness of a mixture of three primary colors, red, green and blue, and many people experience the problem of using a digital video camera: images taken in a fluorescent room Green, the scene photographed under the incandescent tungsten light will be yellow, while the photos taken in daylight shade are somehow bluer, the reason is that the 'white balance' on.

3, color reproduction

The 24 Color Check test card in the studio environment was taken and analyzed by Imatest to get the color deviation ΔE and the white HSV saturation Color difference ΔE is actually the difference between the measured color and the true color.

4, dynamic range

In photography, the dynamic range refers to the brightness range of the subject - the brightness span of the darkest point to the brightest point in the subject, and the shading color card in the studio environment, which is calculated by Imatest to analyze the camera's dynamic range.

Camera parameters, the Nokia 7 equipped with a 16 million pixel Carl Zeiss camera certification, f / 1.8 large aperture, with dual color temperature LED fill light front camera pixel 500 million, f / 2.0 aperture, the unit pixel area of ​​1.4μm , 84 ° wide angle, to support dark light landscaping.

Speaking of the past, Nokia's cell phone, the most representative is the 'Carl Zeiss' certification lens, Nokia 7 also live up to expectations 'Carl Zeiss' certified lens, the sensor for the Samsung S5K2P7SX, specifications and Sony IMX298 is very close, vivo X9s is also used after this, 16 million pixels, the unit pixel 1.12μm, aperture F1.8, but no optical image stabilization.

Then Carl Zeiss certification strength how? We take a look at proofs.

Daytime proofs

Night proofs

Taken together, the Nokia 7 'Zeiss lens either daytime color reproduction, white balance or night details can be accurately demonstrated, without losing the details of the screen transparent, big backlighting environment also has a strong adaptability.

However, somewhat regrettable that the Nokia 7 does not use now flagship standard 'dual camera', so Nokia 7 also do not have the ability to bokeh, imagine, if Nokia 7 in 'Zeiss' blessing under the camera to join the double shot, both 'Merge into one 'there will be amazing performance.
