And just to take things to extreme, this is the most detail I can get, zoomed to 420mm, 4x digital zoom. It would require more than 10,000 exposures to shoot the entire panorama at this level, ~40 TB. I don't think even irfanview would open that one.

That church steeple is .54 kilometers (.34 miles) away, according to Google Earth.
