EVF is an abbreviation for Electronic View Finder. In a digital camera which lacks a reflex finder, a live video image from the sensor may be streamed to a small monitor display with an eyepiece, typically as an alternative to a larger back LCD display.

Early EVFs were prone to many faults, such as poor resolution, slow refresh rates, and smearing of the image. However the technology of EVFs is advancing rapidly; many users find a 1.4 million dot display (found in the Olympus VF-2 or the Fujifilm FinePix X100) to be a viable replacement for an optical SLR viewfinder.
