Capability of Sony Cyber-Shot DSC-RX1R II Full Frame Digital Camera


“Tokyo, the capital of Japan, is the world’s largest city. Located in the eastern part of Japan’s Honshu Island, the southern end of the Kanto Plain, and the international air port, it is the hub of Japan’s political, economic, cultural and transportation fields. For tourists, it combines Japanese tradition and modern civilization. There are many scenic spots and it is a super city worth visiting. “

No.1 42.4 megapixel backlit sensor

Sony Cyber-shot RX1 RII Digital Still Camera has about 42.4 million pixels, twice as many as the mainstream 20 million pixel level products. High pixels naturally have the advantage of high pixels, and the most obvious advantage is to support large-scale image output. But usually we rarely take pictures with such output. On the contrary, the most used high-pixel is flexible cutting function. The pictures after the cutting of the above two pictures still show high-sharpness details, and the pixels are also very high. Comparing with the original image, we can find that a large part of the image has been clipped, and only a part of it has been retained. Even so, the remaining pixels are still enough for network sharing and conventional size image output. That’s the magic of super-high pixels.
In Sony RX1RII, the need for high pixels is also reflected in the fact that it is a fixed-lens camera. 35mm can not meet the requirements of composition in some occasions. It is necessary to do secondary composition by cutting later. If the image pixels are insufficient, the practicability of the cut photos will be greatly reduced.

“Kyoto is one of my favorite Japanese cities. It retains a lot of historical traces. Of course, Kyoto itself is also included in the World Cultural Heritage, so the whole city makes people feel like Japan in the middle of the century. And early December is the season of red leaves. Cherry blossoms and red leaves are a favorite thing for Japanese locals, let alone foreign tourists. “

No.2 Variable Low Pass Filter

Low-pass filters are used to reduce the moire lines when shooting. Nowadays, more and more cameras adopt the method of removing low-pass filters, because the image after low-pass filters is processed will have a lower sharpness. Cameras that remove low-pass filters have been proven to be effective in enhancing image sharpness, and, of course, are more prone to moire lines when shooting certain scenes.
The first product of Sony RX1 series is with low pass filters, while the second product RX1R is a de-low pass filter version of the previous one. Now RX1RII uses the function of variable low pass filters developed recently. It can choose whether to use low pass filters according to different shooting scenes. When it does not shoot high-density regular scenes, closing low pass filters will enhance the sharpness of the picture.
The appearance of moire pattern in image is conditional. Firstly, it is necessary to arrange the objects regularly. The distance between the regularly arranged objects and the adjacent two pixels of the sensor is required to be close. At this time, the signal identified by the sensor is easily disturbed and false signal appears, that is, moire pattern. The output pixels of Sony Black Card RX1RII are about 42.4 million. Such high pixels make the distance between adjacent pixels very small, so the occurrence of Moire lines requires that objects be arranged regularly with very high photographic density. The RX1RII is used to take pictures of the screen of the display. When the low pass filter is turned on or off, the imaging performance is quite different.
It can be seen that the density of the display lattice is close to the pixel density of the camera sensor when the LCD screen is taken at a relatively long distance, so the moire lines appear. Whether RX1RII closes the low-pass filter or opens the low-pass filter effect, there are moire lines in the picture. But when the low-pass filter is opened, the moire lines in the picture are obviously reduced. However, as long as you carefully compare the details, you will find that the details become blurred after opening the low-pass filter, and the sharpness when closing the low-pass filter is much higher.
Pursuing high sharpness performance or reducing moire lines depends on actual needs. Sony RX1RII variable low-pass filters provide photographers with a choice, which is better than no choice. However, in reality shooting, the regular objects with high density such as the dot matrix of the display are always a few, so it is generally recommended that you turn off the low-pass filter to use, and open the low-pass filter if necessary. RX1RII also provides low-pass filter’s surround exposure function. It can take three low-pass filter standard photos at one time for later selection.

No.3 Built-in electronic viewfinder

“Shira-kawa is located at the foot of Baishan Mountain in Qifu County, central Japan. It is surrounded by mountains, paddy fields, and quiet mountain villages flowing by rivers. The special feature of the mountain village is the famous “hand-in-hand construction”, which is the traditional Japanese rural architecture. It refers to the combination of two building materials into a fork-handed triangle shape and the use of straw reeds to lay the roof, the roof is like an open book, the use of reeds to build the roof has the effect of warm winter and cool summer. “
Electronic viewfinder has always been the configuration of high-end cameras, because these cameras are usually large, it is not a problem to configure an electronic viewfinder. But adding an electronic viewfinder to a portable camera is difficult. For portable cameras, every millimeter of space inside the fuselage needs to be well utilized. RX1RII cancels the built-in flash and installs a pop-up electronic viewfinder at the original flash location, which can be retrieved into the fuselage when not in use. The display effect of the electronic viewfinder with 2.36 million pixels is very clear, and 100% visual field rate is very safe to use.
The electronic viewfinder on the card camera has been implemented on Sony RX100III, and the size of the black card RX100III is smaller. Although the electronic viewfinder on RX1RII is not the first one, it is more convenient in design than RX100IV. It can be directly used without pulling out the eyepiece after eyepiece pops up. The focusing device of the viewfinder is set on the side and can be focused by pushing forward and backward.
Sony Black Card RX1RII also provides the viewfinder’s eye mask, which is made of rubber. After installing the eye mask, the viewing comfort is improved obviously, and it will not be affected by the light outside the viewfinder. In addition, when the viewfinder is used directly, if the eye is pressed into the eyepiece, the eyepiece will be slightly compressed, which will cause the focus to move and blur the view. However, when the eyepiece is installed, the position of the eyepiece will be locked, and there will be no defocusing problem. Of course, the viewfinder cannot be retracted to the fuselage after installing the blindfold.

No.4 Picture quality test

Regarding picture quality, Sony Black Card RX1RII has the courage to output about 42.4 million pixels and set the highest ISO to 102400 because it uses backlit full-frame CMOS, improves the sensitivity of a single pixel, and uses backlit sensors. In fact, RX1RII’s high-sensitivity imaging performance is good at such a high pixel level. From the above screenshots, when the ISO is lower than 6400, the granularity of the screen is not very obvious, but the detail sharpness decreases when the ISO is higher than 3200. Because RX1RII uses 35mm fixed lens, the image output matching is better than that of the camera with changeable lens. It is not difficult to find that RX1RII has a very high sharpness at low pixels, even far more than the same configuration of SLR or no-reflex cameras. This is just a palm-sized portable camera. It is undoubtedly the best portable camera in imaging at present.
