Going to be shooting my wife's dance recital this year. I will have the Nikon D7000 or the D5100. Would it be better to have a fixed focal lens with a low f-stop like the Nikkor 50mm f/1.2 AI-S or the Nikon 135mm f/2D AF DC or to have a telephoto lens like the Nikon 70-200mm f/2.8 AF-S VR II.
I will have the Stock lens that comes with the camera already.
