I have been using the NEX-5N for a long time. Since Sony released the NEX 5R, I have been paying attention to it. Although many people say that the image quality of 5R is the same as that of the previous generation 5N, and there is no significant improvement, they decided to drop 5N into 5R due to the flip screen, focusing, wifi and app functions, and started to use it for a few days. Today I will discuss with you a controversial topic: is 5R resistive screen a step backward or a step forward?
Resistance screen and Capacitive screen I don't want to talk about the concept of "DuNiang" here; In this era full of capacitive touch screens, in fact, most people have forgotten the resistive screen. Because the milkshake 5R we started with uses a resistive touch screen, many computer users said, "How come Sony's milkshake 5N upgraded 5R has changed the touch screen from a capacitive screen to a resistive screen? It costs more than 1000 yuan. Is this an upgrade?"
What is the difference between the two screens
① In terms of display effect: the indoor visual effect of resistance screen and capacitance screen can reach the same level.
② Touch sensitivity: The precision of the resistance touch screen shall at least reach a single display pixel, which can be seen when using the stylus. It is convenient for handwriting recognition and helps to operate in the interface with small control elements. The theoretical accuracy of capacitive touch screen can reach several pixels, but it is actually limited by the finger contact area. This makes it difficult for users to accurately click on targets smaller than 1cm. Sony's milkshake NEX-5N and NEX-5R are all three inch LCD displays with a 16:9 screen ratio.
③ As required by the working principle, the resistance screen can work at minus 15 ℃, while the typical operating temperature of the capacitive touch screen is between 0 ° and 35 °, requiring at least 5% humidity (limited by the working principle). Therefore, in the cold northeast, the capacitive screen is not very stable, and touch failure may occur.
From the above three points, on the same small area touch screen, the touch precision of resistance screen is higher than that of capacitance screen. Here is a description of Sony 5N and 5R screens.
In the process of daily browsing the main interface, the capacitive screen is more convenient than the resistive screen.
In the process of touch focus shooting, the resistance touch control of a single point is much more accurate than the capacitive screen. In the process of screen typing input, the phenomenon of mistakenly touching other letters and numbers will not occur.
Touch focusing+release shutter, the resistive screen can improve the sense of operation and reduce the false touch rate, which is one of the reasons why Panasonic uses the resistive screen. NEX only has touch to select focus and touch to automatically select focus. Now with touch focus+release shutter, it is natural to learn from Panasonic, which has done a better job in this area.
Students who have used the NEX 5N will know that the 5N capacitive screen is not sensitive and has poor accuracy. When using the screen, they often touch the function key at the lower right corner by mistake. The size of the NEX series options is about the same as the letters on the keyboard. If you want to select a certain item, it is easy to select another item because of the wrong touch.
The necessity of touch
Although the small editor seldom uses the touch screen when using 5N, touch control can quickly switch the focus, significantly improving the speed of composition, which is much faster than manually adjusting the focus.
Switching focus sometimes requires more accurate positioning, not just switching from one large area to another. Therefore, the smaller the touch contact area, the more accurate it will be. The resistance screen will be better than the capacitance screen at this time.
In addition, in the manual focusing mode, touch click zoom in is still very useful, which also involves the problem of fast composition. Manual focusing is a bit slow originally, and it will be even worse if the focus is selected slowly (the problem of capturing fast composition also exists in the manual focusing mode).
Summary
This article talks about the screen. Sony NEX-5R, as an upgraded version of NEX-5N, changes the screen from capacitive screen to resistive screen, which actually improves the controllability of the camera. The resistive screen is superior to the capacitive screen under certain circumstances. In the actual process of playing, because of the existence of the resistance screen, the phenomenon of mis touch or inaccurate focus that often occurs on 5N is reduced a lot. When the weather is cold, wear gloves, and you can also operate the 5R touch screen. It is not so easy to replace the NEX-5N.
