Viewfinder magnification and viewfinder field of view are important indicators to measure the performance value of the viewfinder. Do you understand? If you don't understand it, let's ask Xiaobian to answer the finder magnification. What is the viewfinder field of view? What is the viewfinder magnification? Viewfinder magnification refers to observing the angle of the subject's eye to the eye through the viewfinder and directly observing the ratio of the subject's angle to the eye with the eye, that is, the size of the subject seen through the viewfinder and directly seen with the eye. The ratio between the size of the subject. The magnification is large, the visual angle is small, and the scene seen when the scene is viewed is close to the original, and the realism is strong; on the contrary, the magnification is too small, it is difficult to observe the details of the object, which is not conducive to composition and focusing, and the object image is very different, and the framing is not Comfortable. The magnification of the camera is generally less than 1 times, mostly between 0.75 times and 0.95 times. The magnification of the viewfinder is one of the main indicators to measure the level of the camera. What is the viewfinder field of view? The viewfinder field of view is the ratio of the range of view of the camera viewfinder to the actual recorded image range of the film or image sensor. In order to minimize the size of the camera, the range of images we see in the viewfinder is mostly smaller than the actual range recorded by the film or image sensor, so we will see in the camera manual that "the camera has a viewfinder ratio of 93". Description text for the class. However, there are many advanced professional cameras whose viewfinders have a field of view of 100%. Most large-format cameras with rear viewfinders have a field of view of 100 on the frosted glass.
