The Gratical HD EVF is a complete electronic viewfinder that incorporates the very latest in OLED and processing technology. Unlike with an optical viewfinder or standard electronic viewfinder, with Zacuto and the Gratical HD EVF, you can trust you’re seeing a realistic visualization of your final image without having to look away from the eyepiece.
Recenlty, the company also added the SmallHD 501 monitor, which retains the features of the 502 except for the SDI In/Out but at a lower price point, allowing DSLR users and those who do not have SDI capacity on their cameras to take advantage of the incredible features of the 500 series monitors from SmallHD.
