HDSLR cameras are taking off in a big way as cheap video rigs with quality interchangeable glass – but the more you get into SLR filmmaking, the more obstacles you find yourself working around. One of those obstacles is that you can't stick your eye to a viewfinder – you have to watch an LCD screen. And in harsh sunlight or wide aperture conditions, that makes it very difficult to get a tight focus on the action. And that's exactly why Zacuto's Z-Finder EVF was built; it's an alternative plug-in LCD screen for your DSLR that can be mounted on a frame or held separate to the camera. It's got higher resolution than your camera's screen, it's got a rubber eyepiece to block out ambient light, and a bunch of other pro video-friendly features that help move your DSLR closer to a proper video camera form factor.
