Thanks for all your kind comments. I did not have much time to reajust the camera setting....tigers move so fast in the wild and just the adrelalin of seeing one in the wild made my heart race and I just hoped to be able to get a picture. It was quite a distance away too and the camera was not too up to date. However, have now brought the new Canon 40D and a few lenses in the hope that my next attempts are better able to capture what I want....and in proper focus too!
Thanks all and happy snapping
