[QUOTE="aroy, post: 493875, member: 16090"] 55mm at 300 feet is asking for a lot from the system. At 28.5 degrees FOV, at 300 feet the view is at least 150 feet wide, that translates to 40 pixels per foot - the head will be just 20 pixels. At that distance the minimum you need is 300mm, which will give you a field of view of around 27 feet - 220 pixels per foot.

The 300mm F4 AFS is the least expensive Telephoto Prime that can be used wide open for distant objects. [/QUOTE]
