So, my first post on this forum: My Olympus 45 mm f 1.8 (on the list) arrived today and performed nearly flawlessly in ground and flight tests. Being a longer lens, though in a smaller form factor, it did produce intermittent jello in a light gusty wind, but in a hover that smoothed out and produced some really useful imagery. I was able to count people on a beach nearly a mile away hovering at 200 feet. No issues whatsoever with calibrating or controlling the lens. It worked straight out of the box, UV filter installed but hoodless, with no additional weights or tweaks. Based on the discussion here so far, I don't think changing the balance will improve the occasional jello. With a 23 degree FOV (compared to 94 on the factory lens), any and all motion is magnified; it just doesn't show with a wide lens, is my theory, since the angular deviations are so small. The flight and camera controls can be softened up to smooth things out a bit, and the payoff is an image that is pretty dramatic. It is like having a whole new system. I like. So far, very good. If I run into problems, I'll update this post.
