A universal, high quality EVF that embraces modern technology and frees filmmakers to focus on Innovation, Inspiration and Creativity. That was our goal when we set out to create a new electronic viewfinder over three years ago. And now the Gratical HD and Gratical X EVFs are here! Electronic viewfinders are a pivotal tool in any filmmakers bag, providing accessibility, stability, focusability and so much more. The Gratical EVF is universal for all cameras incorporating both HDMI and SDI. Our bright, brilliant optics, FPGA dual core processor, and professional software features give you all the tools you need to stop focusing on your equipment and start creating!
