* Actual available lens shift is reduced when the lens is to be
shifted in two directions combined (see Shifting the image , in
section 2. Installation ).
** Lens extension is the distance from the outer end of the lens
to the front of the projector. It is important for calculating throw
distance accurately (see Useful lens calculations, in section
2. Installation ).
