What is the camera policy at Citifield?
Are DSLRs OK?
What are the lens size limitations?
80-200mm f/2.8 OK ?
300mm f/4 OK?
The above lenses are consumer lenses about 10" long by about 3.5" in diameter. They are not as big as the lenses the pro photogs are using such which would probably be 200 f/2 or 300 f/2.8.
I saw fans at Yankee stadium last year with lenses that size.
