Other notable features include: Super-Multi-coated optical elements for a bright, clear view of the subject; an inner-focus design for objective lenses; a long eye relief (22mm); extendible helicoid eyepiece rings; click-stop diopter adjuster; durable rubber-coated outer housing; eyepiece caps which double-function as rain shields; and a tripod socket for extended viewing.
