Having gone to a few airshows this year and been fairly pleased with my results, I looked at a telephoto converter for my S9600. However, negative reviews and disappointing availability mean I'm ready for the plunge into a proper SLR. I like the look of the 30D and 40D and should have the budget for either (seen great shots with a 1D Mk III, but that IS over budget ). What is making my choice difficult is I have no idea where to go for a good telephoto lens for either of these cameras. I am looking at a total budget of around £1000 at the moment, but that's flexible for the right kit.
Any suggestions appreciated.
