lens extension, measured from
front of corner post
* 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 measured when the lens
is focussed at in
fi nity 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 ).
