Helicopter Parts Make For Amazing DIY Camera Stabilization

Iddo Genuth writes "Videographer Tom Antos developed an advanced DIY camera stabilizer which can hold almost any DSLR or mirrorless camera steady for video photography. Although this surely isn't as sophisticated (and super expensive) as the professional MVI M10 handheld 3-axis digital stabilized camera gimbal, its still quite impressive especially when you consider it only costs a few hundred dollars rather then tens of thousands — that is if you feel like building it yourself." Antos' design takes advantage of stabilized gimbal systems made for hanging cameras on remote-controlled helicopters, and does a very impressive job for its price.

      Are you sure that this is the most serious issue? If the vanishing point is on screen, I'd think it would be stabilized as well. What's much more interesting is the perspective change in wide angle shots - that's the one thing you can't compensate with changing the crop window. The vanishing point is simple to deal with because it's just a point (it's a 0D object), but the altered perspective can change a rectangle into a parallelogram or vice versa. You'd essentially be creating a digital version of a shift lens which is not what you want in a video, unless you're aiming for psychedelic.

      There's also the issue of the view finder. If you're using an EVF it's not an issue, but with OVFs, the view you're getting is still as jerky as it was without stabilization, which can make it a challenge to frame what you like. Sure, it cuts down on some of the blurriness, but you lose out on a lot of the benefits.

      Which is rather unfortunate. I've got a Canon lens with optical IS built in and I can really tell the difference, I can go from being unable to frame a shot, to being able to get a reasonably sharp image, when I turn on the IS. It's a shame that it comes with the nasty drawback of requiring the hardware in each lens that I need stabilized.
