What is the best handheld portable setup for digital camera for telephoto wildlife and sports photography, without having to get a huge lens which requires tripod. I am guessing 70-200mm 2.8, and for extra reach add a 1.7 teleconverter? I am not sure what else I can do other than paying 6500 dollars for the next steup up which is 200-400mm. Using Nikon D80
