Hi, I'm 16 and I'm a SERIOUS art student (currently in high school). I currently don't own a camera but have saved up some money and am looking to make a purchase. I want something that will be good for sports photography, but at the same time is rather versatile for different types of photos (especially people & macro). I am looking to spend around $1500, but because I want something that will last me and that I can use in my art portfolio and in art school while training with photography I will spend more if it is worth it. I have been looking at the Nikon D90 for a while now but I'm concerned after reading reviews about a slow shutter speed (for sports).. I am looking for both a camera and a lens or lenses, or a package where i can get a discount (but with good lenses please) would be great too. Any help or suggestions will be much appreciated. Thanks.
