Clear picture, light weight, reliable - that's what I need in a field monitor and that's what I get with SmallHD. The DP4 is my go-to monitor for any situation where I want to be low profile, but need something more than the camera's on-screen LCD screen. Plus, with all the specialty camera gadgets I'm constantly using, the on-camera monitor is rarely even an option. Because the DP4 has HDMI loop-through, I can get my picture for framing and feed a signal out to several SmallHD AC7 monitors via a Teradek Bolt wireless video downlink for my focus puller, video village, etc. Regardless of the situation, I cannot think of one where my SmallHD monitors are not an integral part of my shooting setup.
