I've been shooting my daughters high school volleyball the last two years with just mediocre results. At the end of this season I rented a Nikkor 85/1.8 and was amazed at the improvement from this fast lens. I could use even more speed, but the 85/1.4 is just too expensive. So I'm trying to decide between the Nikkor 50/1.4 or the 85/1.8. If you shoot volleyball, or other indoor sports, I would appreciate your insights regarding these two choices. I should point out that I also shoot high school basketball, but the "need for speed" in volleyball is far greater than basketball. It's not difficult to freeze a basketball in flight, but the volleyball flys much, much faster. Ergo, the need for a very fast lense. Thanks.
