As you may guess I am new to this site and New to Nikon. I've had a D5000 for about a year now with a 18-55mm lens and a 55-200mm lens. I am a week ender just taking pictures of the grandkids,my oldest grand daughter is playing field hocky and the 55-200mm lens is not enough most most of the time. I was checking out a Rokinon 650-1300mm lens I know on my D5000 it will only work as a manual lens but does anybody has this lens using it in this type of setup. I guess what I am asking is this a ok setup for a week ender will it give good results for hobby photographer.
