This is the 5" Ninja Blade monitor / external recorder. You gotta love it's ability to turn a Canon C100 effectively into a C300, and it's image is a vision of beauty compared to the C100's native LCD Screen.

In addition to the Ninja Blade Package (contents listed below), this package includes two (2) 256GB SSD Drives (which often are half of the rental cost through other providers), an HDMI Cable, and a basic mount that will mount the Ninja Blade onto a hot shoe mount.
