Bought it for use on the istD, and was quite dissappointed by the lousy AF performance. It failed to AF about 50% of the time, needing really good contrast/much light to succeed. The image quality was OK (considering the zoom range) with the expected sofness at the long end, but quite acceptible for snapshots and hollidays. I was about to sell it, but found it works a lot better on the K10D so I might keep it, much for the same reasons you stated ...
