Dear Unk,

Many lenses are convertible, that is, by removing or switching a rear 
element, the focal length is changed.

My Nikkor T*ED lens is a 360/500/750mm lens. One shutter and front element, 
three rear elements. Very easy to carry.

My old Symmar 210 was a convertible. Removing the rear element turned it 
onto a 420mm lens if I remember correctly.
