ELICAR newly developed super telephoto lens is 2160~8640mm f/4.1~5.7, of

lens construction of 19 elements in 16 groups including 4 ED lenses, being perfect 

for very distant surveillance and observation.  Optical quality is so high that this

lens will not need a housing and  performs incredibly through the window of ofice,

house, observation post, etc.
