I am shooting a state high school basketball tournament in a large college arena. I shot there a year ago with a Nikon D300s and the 50mm f/1.4D. I have since added a full frame body (d700) and added the newer 50 f/1.4G. I shoot basketball year round and have figured out how to get what I need need in poorly lit gyms from the baseline with the 50. Photography is only part of my job but I have a dilemma for the upcoming event. With and extra body I am thinking of renting a second lens for the week. I've narrowed my options to the 85mm f/1.4G and the 200mm f/2.0. I plan on buying the new 85 later this year. The lighting at the Erwin Center is better than most high school gyms but I don't feel comfortable going with 2.8 zooms. From what experience I have most of my shots at 1/400-500th are at f 2.2 or wider. I've never used the 85 sonI'm wondering if it will give me a different enough perspective from the 50 or if I should spend a little more money on the 200. Thanks for the feedback.
