What is a rangefinder camera and how does it work?

A rangefinder camera is also a rangefinder camera. That is to say, the lens and viewfinder of this type of camera are separate. What is seen in the viewfinder is not the same as what is seen in the lens, but there is a certain parallax. Since the shutter is designed on the lens, most rangefinder cameras cannot change the lens due to mechanical linkage. The viewing channel of the SLR passes through the reflector and is consistent with the image on the film (or digital final), that is, what you see is what you get. Shutter: SLR: There are many gears. The shutter speed of modern SLR cameras can range from 30 seconds to 1/8000 seconds; relatively speaking, the vibration is relatively large and the sound is relatively loud. Rangeshaft: The number of gears is small, usually 1 second to 1/300. A few high-end machines can reach 1/500. The vibration is small and the sound is small. Viewfinder: SLR: No parallax rangefinder: Parallax exists Lens: SLR: Interchangeable lens rangefinder: Non-interchangeable lens Focus: SLR: Accurate and fast focus Rangefinder: Relatively difficult to focus Flash synchronization: SLR: The synchronization speed is relatively slow, general horizontal The curtain walking is 1/60, the vertical walking is 1/125, and the fastest is 1/250. Rangeshaft: Fully synchronized. In terms of volume: SLR: larger and heavier; rangefinder: small and lightweight. When shooting: SLR: Because the reflector flips up, it blocks the light from reaching the viewfinder through the pentaprism. Therefore, the viewfinder is black at the moment of shooting. Rangefinder: Because different light paths are used, the scene can be seen through the viewfinder at any time. Suitable for situations where you need to continuously observe the continuous movement of the subject. Consumer-grade digital cameras (DC) are a little different. Most digital cameras do not have an optical viewfinder. The light reaches the CCD through the lens and is then converted and displayed on the LCD screen. There is actually no parallax anymore. It can also be said to be equivalent to the SLR mode. And the DC shutter is different from the traditional shutter. There is no mechanical shutter. The "shutter" function is realized through circuit design. DC’s shutter sound is specially designed by designers to adapt to people’s traditional photography habits, so as to tell the photographer: “I have taken the picture.

” Digital SLR cameras are similar to traditional cameras, except that the film position is replaced by CCD or COMS
