The difference between optical framing and electronic framing

1, the working principle is different.

The optical viewfinder is realized by the pentaprism structure built in the fuselage, which directly reflects the scene in front of the lens through light and transmits it to the viewfinder without processing.

The electronic viewfinder has gone through the process of photoelectric signal conversion.

2, the shooting effect is different

What you see in the optical viewfinder is often different from the photos you take. Photographers cannot predict the exposure results and control the depth of field through the viewfinder, which requires higher skills and experience for photographers.

The scene displayed by the electronic viewfinder will change with the adjusted shooting parameters. You can view the histogram so that the photographer can adjust the exposure parameters immediately to obtain the desired effect, not based on photometer and experience.

Advantages and disadvantages of optical viewfinder:

Advantages: the eye socket is called by the viewfinder, and the motion range is small when taking a view, which is conducive to holding the camera steady. The viewfinder does not need electricity, and the camera saves electricity.

Disadvantages: there is parallax between the viewing range of the lens and the actual shooting range, that is, what you see is not necessarily what you get. When shooting a long-distance scene, the error can be ignored, but when shooting at a close distance, the parallax is larger, and the closer the shooting distance, the greater the parallax.

Disadvantages of electronic viewfinder:

The disadvantage of electronic viewfinder is that the display quality will be somewhat different from that of real SLR cameras.

Because of the low resolution, the color of the image is not as bright and delicate as the captured image itself. It looks rough and grainy. The smallest details of the captured image, such as whether the human eyes are open, cannot be displayed.
