Lovely shots CGS. MyY fave is the second one even though I can't remember its name. I believe it's in the same family as the capybara and agouti but can't be sure. Superb focusing, which lens was that with? I am guessing the 70-200mm lens that you list in your Gear.
The tiger is also superbly focused, maybe just a tad tight on the cropping but stunning sharpness all over.
Really good work, well done
Cheers,
Rob
ps Which safari park was this? Woburn is close t you so am just guessing it could be there but maybe elsewhere?
