After a lot of agonising, and after some helpful advice from BF members (like "buy it!") I now have a Canon IS lens, with a 1.4 x teleconverter. First impressions are very good. The image stabilisation is excellent and is especially useful with the teleconverter added, where camera shake is very obvious otherwise. The optical quality seems much better than that of my old Canon 75-300 f4.5-5.6 USM lens. Autofocus is quick and accurate, although does not operate with the teleconverter (I understand there is a way round this).
My local buzzards were an obliging first target. These pics were hand-held and manually focussed with the teleconverter giving 560mm focal length (equivalent to about 800mm with a film SLR; I use a Canon 300D digital SLR). Yes, I know one of them has an overexposed background!; that is because the buzzard was near the line of the sun (and I had to be careful not to blind myself). The little grebe was a fair distance away for the other attached shot.
