The Sony DCR-PJ5 has a better image stabiliser type than most small sensor size camcorders that have been available for a comparable time to it. This Sony camcorder has a Digital image stabiliser, whereas most small sensor size camcorders that were launched around the same time as it have an Optical image stabiliser. Some compact cameras have digital Image stabilisation only, which simply boosts camera sensitivity (ISO) to obtain a faster shutter speeds to help prevent blur. No hardware is involved.
A Digital image stabiliser is actually the worst image stabiliser type across all comparable spec camcorders that were released more than two years ago.
An Optical image stabiliser is the best image stabiliser type amongst similar types of camcorder.
