I'm sure some Scarlet owners have the Canon EF-S 18-200mm F/3.5-5.6 lens, at least as part of a stills kit, and have tried it on the camera with the smart mount.
Without regard for its optical worthiness (I know it's inferior glass and that there are many lenses to recommend over it) here are two questions:
1. Does it work reliably with all of the camera functions, aperture manual and auto focus, Redmote focus etc.?
2. How's the coverage? I assume it covers 4K but are there any vignetting issues at 4k or 5k?
