200 yards is a long ways away. What power scope would you need to see a man's silouette (sp?) full frame at that distance? Probably more than a 3-9X scope could provide, I'm guessing.
Now, in photo terms, a 3-9X scope would be the 35mm SLR equivalent of a 150-450mm zoom. (When you read "X," think "power.") A camera lens with that range would be pretty pricey. Off the top of my head (and using Nikon as an example since that's the system I use in my jobs), while there are no zooms in that particular range, a new 200-400mm Vibration Reduction Nikon zoom lens runs just over $5000.
Surfing photographers who shoot from the beach set up 600 or 800mm lenses (and longer) to capture up-close images of their subjects. Believe me, those pieces of glass are worth more than my truck!
Also, from what I've been told, digital zooms produce very degraded images. If you're looking for sharp pictures, rely strictly on the glass, not a cheap computer program. HTH
