Hi again everyone, thanks for comments, went to the zoo again this afternnon, the Lionesss & cub were out again (poor old male Lion was locked inside), I could watch them for hours, in fact I did!, I was glad when they moved so we all rushed to another point because my legs were starting to get stiff.
Simmontino, I was quite pleased with the IQ yesterday with the 2x converter on the 70-200, I also have a 1.4x, today I thought I'd experiment & stacked the converters, results were pretty good, but good light levels were needed, auto focus worked fine & fairly quick on animals not taken through a fence, but for the Lions I switched to manual focusing.
I'll post an image up soon.
Regards Kevin
was nice to talk with other Togs there
