This means that if you see a critical moment happen in the EVF, it has already happened in the “real world”.

The disadvantage of an electronic viewfinder is that the electronic display has historically had a slight “lag time”, or delay, between the image being captured on the sensor and replayed in the viewfinder. There are many other advantages to an electronic viewfinder, including the ability to display much more information such as a live histogram, focus peaking, exposure warnings for highlight or shadow clipping, and other things. This aides the photographer in both eliminating technical mistakes, (such as accidental underexposure or incorrect white balance) and also in creative artistry, by showing what creative effects will look like such as dramatic, intentional high-key or low-key exposures. The advantages of an electronic viewfinder are that the “final image” is represented exactly as it will be captured, which is known as “what you see is what you get” or WYSIWYG.

An optical viewfinder can be viewed even while the camera is turned off, and consumes little to no battery power while the camera is on.Ī wealth of information can be displayed in an optical viewfinder, including exposure settings, metering information, flash and white balance information or warnings, and focus confirmation for manual focus lenses.Įlectronic viewfinders, also known as EVFs, use the image sensor itself to record what the sensor is seeing, and play it back on a digital display inside the viewfinder for the photographer to see. The advantages of an optical viewfinder are that the “real world” is represented exactly as it is, and exactly as it happens. Some cameras have different viewfinder designs, such as rangefinder cameras, which do not actually look “through the lens” (TTL) but instead have a separate viewfinder window. Most optical viewfinders use a mirror, a focusing screen, and a glass or mirror prism to allow a photographer to see through the lens itself. The viewfinder must be held up to the photographer’s eye to be seen, as it is built into the camera itself, as opposed to a LCD display or focusing screen that is visible from a distance, such as the ground glass of a large format camera, or the live view feature on a DSLR or mirrorless camera.įor many types of photographers, from action sports shooters to candid portrait shooters, having the camera raised to the eye is beneficial in that it allows the photographer to be fully involved in the viewing of their image before it is clicked, undistracted by other surroundings, as well as being discrete in certain ways. Most serious cameras have a viewfinder, whether it is an electronic display or an optical prism.
