Nowadays all the cameras bring a built-in screen to frame and visualize what we immortalize, but many of us continue to cling, with nostalgia, to the traditional viewfinder, putting one eye on the camera while we wink the other. Both screen and viewfinder have their respective advantages and disadvantages, but did you know that the viewer itself is divided into several types, also each with its strengths and disadvantages?
VIEWFINDERS: OPTICAL VS. ELECTRONIC
Mainly we find two types of viewfinders in current photo cameras, optics and electronics. The first, optical, as its name suggests, use a combination of mirrors and prisms inside the camera to bring the image to the viewfinder. The electronics, on the other hand, transmit the same image of the sensor, in a kind of mini-screen, exactly as if it were the screen on the back of the camera. Each of us will have a different preference, but both the optical and electronic viewfinders have their advantages. On a personal level I prefer optical viewfinders because they offer a clear, real, unmodified or treated image, a virtually identical copy of what our eyes see. Another advantage is that, when reflecting a real image, they do not present that small delay that some cameras with electronic viewfinders could present. On the other hand, optical viewfinders better manage high contrast situations between illuminated and dark areas (what is known as the Dynamic Range). Imagine a scene where there is too much light in one part of the image, but the other part of the image is too dark. This would not present any inconvenience with the optical viewfinder, but with an electronic viewfinder the image would be slightly modified. It is a limitation of the camera itself. In favor of the electronic viewfinder it must be said that it shows the image exactly as the sensor would take it. Keep in mind that the electronic viewfinder is a kind of "repeater" of the sensor. The image you see through the optical viewfinder is an image that has not yet passed through the camera's sensor. The one you see through the electronic viewfinder, however, has already passed through the sensor. This allows you to know with certainty the final result before shooting, which, with the optical viewfinder, there are times when it may not give the same result. Another advantage of the electronic viewfinder is that, through it, the image is not interrupted at any time. With a traditional optical viewfinder you can view the frame and make all the adjustments but at the time of shooting you lose your vision momentarily. It is a mechanical limitation, typical of all cameras with optical viewfinder and mirror. This with the electronic viewfinder does not happen.THE BEST VIEWER?
Most SLR cameras usually carry an optical viewfinder. The electronic viewfinder is usually found more frequently in bridge , bridge, mirrorless and compact cameras . There is no general rule by which one type of viewer is better than the other by default. I've seen good optical viewfinders and I've seen them bad. With electronics I have had a very limited treatment but I have photographic friends who use them without any problem.
