Nokia do this type of video better than any other conmpany, I think. Included below is a video demonstrating the internals of its 'PureView phase 2' camera, i.e with Optical Image Stabilisation (OIS), as used on the Lumia 920/925 and 928. The detail in the parts explosion is terrific and you have to wonder if they're not giving the competition a bit too much of an insight into how it all works (I guess Samsung, LG and Apple could just buy a device and tear it apart, but still...) Anyway, of interest to camera phone hardware geeks everywhere.
From the video below, there were a few stills worth commenting on. In the screengrabs below, you can see the intricate system of frames, springs and MEMS actuators that manipulate the entire optical assembly:
Being able to do this full assembly OIS while still providing moving-lens autofocus is very cool indeed, especially at this scale. Fascinating stuff, and we've seen the benefit of the OIS for video capture in particular (for example, here).
