** Actual available lens shift is subject to limitations of the lens
mount (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 measured when the lens is
focussed at infinity and fully extended. At other focus settings,
the extension could be up to 10mm less.
It is important for calculating throw distance accurately (see
Useful lens calculations , in Section 2. Installation ).
