Tested the 1DX Mkii on the Letus Helix, so far all is good. Still sorting through the manual. Took some test shots over the weekend verse my Sony A7ii and A7Rii. The Canon is way cleaner, requiring far less gain to expose in low light conditions that either of the Sonys. Video look pretty good to my eyes, even in dark (not just low-light) conditions, whereas the Sonys produced unusable footage under the same condition. We did have some rain over the weekend, and I had no fear, safe in the knowledge that this body is fully weather-sealed.
