[QUOTE="J-see, post: 428896, member: 31330"] You can not pick a cell mast at 2 miles and fine-tune focus to that. The advised distance for a 300mm is 50*300mm = 15 meters = 50 feet. You can go shorter or even a bit longer but 0.5 miles or 2 miles is surreal. If you shoot at infinity, how can you add +5 and check if it now focuses further. There's no infinity +. [/QUOTE]
