The Zacuto Gratical Eye has become my EVF of choice since picking one up last month. The smaller form factor is perfect on a variety of cameras, including popular models like the C300 and FS7.
The build quality seems excellent but I’m not volunteering to drop test it to find out if it survives. Luckily Steve and Jens from Zacuto have decided to do just that and film it for our benefit. Very reassuring.
