The Sony HDVF-EL30 0.7" Full HD Color OLED Viewfinder with 3.5" Display is used with a wide range of Sony cameras that feature the 20-pin round HDVF viewfinder interface. It features quick pixel response for tracking and focusing on moving objects. The use of OLED (Organic Light Emitting Diode) display technology helps deliver excellent contrast and a wide dynamic range.The viewfinder's specially developed optical loupe provides a high eye-point, which allows operators to see a wider area of the picture if they stand back from the eyepiece.

The image displayed on the viewfinder can be downscaled via the menu or assignable button to avoid vignetting.The HDVF-EL30 is equipped with an additional 3.5" qHD (960 x 540) sub-LCD display for direct monitoring over a longer distance. Using both sub-LCD panel and OLED display offers full operational flexibility, enabling a camera assistant to monitor the sub-LCD display while the camera operator uses the OLED display.
