lens, and does a very effective job.
But Sony ran into problems when they used this mechanism for stabilizing
movies (like on their first SLT, the A55). Having the sensor move
constantly for extended periods of time (instead of just the duration of the
exposure) tends to generate a lot of heat, and long movies on the A55
would often terminate prematurely due to thermal shutdown.
The solution? Keep the sensor perfectly still during movies. Record a
slightly larger image area than what your viewfinder tells you you’re
shooting, and then use the same kind of in-camera image alignment
technique used in the HDR feature. The extra overlap is used to fill in the
edges of the frame so you don’t have fuzzy edges with an unsteady hand.
This technique may be CPU-intensive, but at least it’s better than the heat-
intensive method used in the A55.

Normally this would be the part of the explanation where I give the
disclaimer, “If your camera is on a tripod, turn SteadyShot OFF because
you might have some phantom sensor signal correction”. However, having
tried this in movie mode, I actually don’t see any phantom motion
correction. It’s as steady as a tripod. Therefore, I can think of no good
reason to ever turn this feature off.

Digital cameras can only store numbers, not colors. And so it is very
important that everyone agree on a way to represent colors so that what
looks like red in the real world also looks like the same shade of red on
your monitor and on your printer as well.
