Hey, so I bought a Nikon D7000 earlier this year and I have enjoyed it ever since, but I am quickly getting tired of the 18-105mm kit lens, its not a bad lens but I am thinking about picking up a prime lens possibly the (50mm f/1.4; the 50mm f/1.2 is a tad out of my price range). Does anybody have recommendations for any future lens purchases? I have family coming out from Indiana to my home soon, and since I live in Southern California we are doing the whole theme park shuffle thing, so any suggestions regarding an ideal lens for that situation would be greatly appreciated (I was thinking prime lens in order to be able to take photos on the darker rides, but I am sure most of you know better than I). Also take note that I'm not a professional photographer, and I only have a basic understanding of cameras and lenses, so I don't have the money to purchase a ton of expensive lenses and equipment nor the knowledge on how to use it all. Thanks.
