Thanks to all those who have replied. As a result of the responses, I've discovered some new advantages of digital zooming that I hadn't considered. Also I've been corrected on my misunderstanding about digital zooming requiring a faster shutter speed to cope with increased camera shake. That was a surprise to me! This must be different from using a teleconverter to increase the effective focal length of a lens. I assume this would require a faster shutter speed. My reason for starting this thread was not to slag off digital zooming, but to ask a question (admittedly in a provocative way!) which I hoped folks more knowledgeable than I am would be able to answer for me ( which you have). I don't think it's been pointless. Thanks again to everyone for your contributions.
