After reading this blog, and checking out both the Peau Productions, & Carolina Dronz websites, I'm considering the idea of not only swapping the lens on my current CGO3+, but also the idea of purchasing a second CGO3+ and having that lens swapped. This way, I'd have two CGO3+ cameras...one with the 3.97mm lens (almost equivalent to the stock lens' focal length & field of view), and one with the 8.25mm lens (41 degree field of view). It might be considered by some to be an expensive way to go, but, considering the CGO3+ doesn't have interchangeable lenses, this could be considered the next best possibility.
Since I already have a SteadyGrip, how I thinking about this is to purchase a SteadyCam (ie. SteadyGrip with CGO3+ included). Then, I'd be able to simultaneously do aerial & ground-based footage...or, if I so chose, two ground-based cameras, with different focal lengths. "Changing lenses" on the Typhoon H would be as simple as swapping CGO3+ cameras/gimbals. If Peau Productions ever came out with an ultra-wide angle lens for the Typhoon H (say, something similar to their 1.21mm f/2.0 220d HFOV 16MP lens), which would be fantastic for straight-down shots, then that could potentially be considered a good reason to purchase a third CGO3+. Not saying I'd do that, as the final cost would be getting up there...but it would be worth considering.
