Good question about the tamron - I have no idea. Since Nikon apparently neither shares nor publishes their interfaces I have serious doubts that Tamron can effectively interact with the Nikon firmware for combined VR/IBIS.Thank you, does anyone know if this works with the tamron lenses as well, or just the Nikkors. I understand the literature says nikkor, but I wouldn't expect them to advertise that other lenses will work well. I know the tamron tap in lets you update their firmware, so if it's possible to update via that, I would think/hope it's either already working or would soon. provided nikon isn't blocking it somehow.
as for the scan banding, yeah, I had seen some of that with someone who shot a concert. The theater I have shot the most stuff with uses rgb leds for almost all their lights, which pose their own problems even without rolling shutters. I'll probably test it with silent shutter, to see if it's possible, but even the normal shutter will be significantly quieter than the D700.
Reverse engineering is a pain.
