The Nikon I am selling is a 300mm f2.8 and a 70-200mm f2.8 lens both beautiful lenses.
You are right about sports photographers poor pay. I would guess 80% of photographers sitting at the side of the pitch at games are not full time and have other jobs.
I Have a couple of high end Nikon lenses perfect for sport photography for sale if you are interested? who knows maybe this could be the beginning of a new career path for you!
Great Pictures by the way!
