MANUAL FOCUS Macro Extension Tube Ring For NIKON Ai AF DSLR & SLR Camera House
features:
An extension tube is an accessory for
cameras with interchangeable lenses, used primarily for macro
photography. The tube contains no optical elements; its sole purpose is
to move the lens farther from the image plane.
The farther away the lens
is, the closer the focus, the greater the magnification, and also the
greater the loss of light (requiring a longer exposure time).
Lenses
classically focus closer than infinity by moving all optical elements
farther from the film or sensor; an extension tube simply imposes this
movement.
