I am looking into buying an entry level DSLR for use as my main camera for shooting indoor shots at events such as basketball games, hockey games, and also outdoor sports such as baseball. I need a lens that will allow me to make the correct zoom so that i do not have to do so much cropping. My question is do you think a 55-200mm lens would be adequate in situations such as these? What size would you recommend? I will be shooting using the Nikon d40, the reason i ask this question is because there is a package deal including a 55-200mm lens along with the stock kit lens of 18-55mm, and i need to know if I might be better off purchasing a different lens separately. I will be standing about anywhere from 10-100 feet away from the subject when i am taking these pictures.
