An electronic viewfinder (EVF) is a camera viewfinder where the image captured by the lens is displayed on a small screen (usually LCD or OLED) which the photographer can look through when composing their shot. [1] It differs from a live preview screen in being smaller and shaded from ambient light, and may also use less power.

The LCD grid can mask effects of spatial and grayscale quantization, creating the illusion of higher image quality. [52] Is the cheapest display technology currently produced, with some entry-level models selling for less than $100. Screen-door effects are more noticeable than LCD when up close, or on larger sizes. [53]
As an inherently digital device, the LCD can natively display digital data from a DVI or HDMI connection without requiring conversion to analog. Some LCD panels have native fiber-optic inputs in addition to DVI and HDMI. [155] Many LCD monitors are powered by a 12 V power supply, and if built into a computer can be powered by its 12 V power supply.
LCoS display technology is a type of microdisplay that has gained popularity due to its high image quality and ability to display high-resolution images. LCos display systems typically consist of three main components: the LCos panel, the light source, and the optical system. The LCos panel is the heart of the display system.
There is a half mirror prism that reflect data from LCD to the optical viewfinder, so we can see both the shooting frame and the shooting data. A button can change the hybrid function to electronical viewfinder by blocking the image through the optical viewfinder with moving a half mirror prism to be a straight up mirror. [5]
The larger, advanced digital cameras offer a non-optical electronic through-the-lens (TTL) view, via an eye-level electronic viewfinder (EVF) in addition to the rear LCD. The difference in view compared with a DSLR is that the EVF shows a digitally created image, whereas the viewfinder in a DSLR shows an actual optical image via the reflex ...
