Re: 10x optical zoom?
32x on a camcorder/camera is not the same thing as 32x on binoculars.
32x zoom on a camcorder means the telephoto end of the zoom lens is 32x the wide angle.
32x zoom on binoculars would mean that at maximum zoom objects viewed through the binoculars are 32x larger than they would be in real life.
The two things aren't really comparable.
Also in this situation the digital zoom is important, the imaging sensor is about 4 megapixels. HD video is around 2 megapixels, that gets you from 10x to 15x without any up-scaling.
