Well, surprise, I heard back from them not once, but twice via email. Unfortunately they were no help at all. The first response was, your camera apparently isn't fully compatible. Well duh, that's what I told them in my email. Wrote back, politely, and said either they need better instructions, a list of non fully compatible camera bodies, or a riser plate of some kind. The second response was, we'll forward your request to marketing, but we don't have any sort of riser, and maybe I could use a grip as a riser? Another duh, that's what I told them in my first email.
So, if you have a big body or grip, or multiple bodies, go for it. It'll still be useful to me, but not the ideal solution I was looking for.
