The HDVF-EL20 is a 0.7-inch Full HD colour OLED viewfinder for Sony cameras fitted with the 20-pin round HDVF viewfinder interface. Quick pixel response keeps the image responsive when tracking and focusing on moving subjects, and OLED display technology delivers high contrast and a wide dynamic range. A specially developed optical loupe gives a high eye-point, letting the operator see a wider area of the picture when standing back from the eyepiece. The displayed image can be downscaled via the menu or an assignable button to avoid vignetting.
