18-32 miles

I could do with a decent zoom.

It’s the equivalent of a 5200mm lens. Can you spot the camera?

The brochure says it will let you see 18-32 miles. A BoingBoing commenter wondered whether the curvature of the Earth might be a factor at that kind of distance.

It would fit onto my 400D. However, the digital sensor is smaller than 35mm film, meaning all lens sizes must be multiplied by 1.6. That makes it a 8320mm lens. To further sweeten the deal, it’ll focus up to ‘only’ 120m away, and weighs a mere 100kg. Via Kottke.
