The mobile phone to be experienced today is the Samsung Galaxy S9+ [SM-G965N]. We specifically indicate the specific model in square brackets. SM-G965N is not officially sold in China S9+, Chinese version is based on Qualcomm Snapdragon 845 with Sony IMX345, and SM-G965N is Samsung's own Exynos 9810 processor with Samsung's own SAK2L3 CIS, which is mainly sold in South Korea, also known as the Korean version. Samsung's screen, Samsung's processor Samsung's sensor, the real Samsung family barrel, this handsome and rich phone's owner sent it to Soomal without hesitation. We are also very interested in this phone, because it is rare, but also very much want to know, Samsung's family support SM-G965N, how the camera can perform.

Overview

[Wpic]ID=00005258[/Wpic]

The S9+ uses a dual camera with long and short focal lengths. The main lens has an equivalent focal length of 26 mm and the sub-lens has an equivalent focal length of 52 mm. This focal length combination is similar to Note 8. The main lens has two adjustable apertures, F1.5 and F2.4 respectively, and F1.5 is the largest aperture in current mobile phones. When in a bright light scene, the aperture will shrink to F2.4 to obtain higher resolution, especially for edge imaging, and low light scene will expand to F1.5, which is helpful to improve the shooting success rate. These two apertures are physical apertures, not analog. Telephoto lens aperture F2.4. Both lenses of the S9+ integrate an optical image stabilization system. Lens configuration, all versions of S9+ are the same, no difference.

The G965N's CIS is not the same as the Qualcomm version S9+. It uses the Samsung ISOCELL SAK2L3. Like the Sony IMX345, the new three-stack architecture is used. It integrates LPDDR4 DRAM and ISP [Image Signal Processor] underneath the CIS. The two CISs are very close to each other, are 12 million total pixels, all have full-pixel dual-core focus, all support 960FPS video capture. But cannot simply think the same, according to long-term experience, at the same time the Samsung CIS to be weaker than the Sony CIS, the gap between the early years is obvious, Samsung is catching up quickly, but never more than. Will SAK2L3 be better than IMX345? Well, we don't have this expectation.

The camera is the big selling point of the S9/S9+ series. The S9 that we have already evaluated is one of the best integrated cameras in the current sale of mobile phones.

The G965N's CIS integrates full-pixel, dual-core focus and is fast and accurate, making it one of the fastest phones currently available. The pre-focus response is rapid, and the G965N can maintain high-efficiency focusing by refocusing in time, in various typical scenes under strong light or low light. The G965N will try to determine the user's intention, gently and slowly change the composition, will try to lock the focus instead of refocusing. The area of the central focus area is large, and the principle of real-time proximity in the area will be prioritized. This will help shoot stills, macros, etc. The telephoto lens of the G965N is also very fast, so we used telephoto lenses much.

The G965N's focusing experience is as good as the Qualcomm version of the S9. It is fast, accurate, and smooth.

The default light metering mode of the G965N is the center-weighted average, which can cope with the photometry of most typical scenes. The result is reliable. In bright light scenes, white objects may have slight spills, but they are more advanced than the previous generation. In the real-time blurring mode, the highlight overflow is relatively obvious. Photometry under low light is well controlled and results are seen close to the naked eye. In light of complex lighting, the light metering results are also basically reliable. Support focus and spot metering linkage, low linkage sensitivity, suitable for rookie use.

The G965N offers exposure compensation tools in both automatic and professional modes, with an exposure compensation range of plus or minus 2EV and stepping 0.1EV. The metering experience of the G965N is not different from the Qualcomm version S9
