Telephoto lenses are usually a preference because you can't frame close enough without them.
On a typical airball field, the instances where you'd actually be giving players away are pretty few and far between. Everyone hits a primary bunker off the break and stays there. Once they start leaving those positions, I stay off them unless a) they start shooting at someone, b) someone starts shooting at them, or c) a coach calls their position. One of those usually happens. It's pretty much just common sense, don't point at anyone being sneaky.
