6 Perfect-Fit
The Perfect-Fit function improves the optical light engine including a fully-
programmable zoom, focus and lens shift feature, which enables a lens-free option to
create 2,40:1 images.
There is the possibility to save the settings for the positions of zoom and focus
corresponding to a video format for 10 different configurations.
To set the custom settings zoom and focus is necessary to enter the SETUP menu and
than in the Lens Functions menu.
To set the custom settings lens shift is necessary to enter the DISPLAY menu.
In the case of off-axis projection, zooming in and out, you get a changing of the center
of the image corresponding to the amount of the off-axis. This changing amount must
be compensated with the vertical and/or horizontal shift (regulated manually).
For non standard video formats such as 1,33:1 and 2,6:1 you need to accept compro-
mise for the final aspect ratio.
A correct setup for 2,35:1 image format, with a 16:9 format inside, is to do not have
an horizontal optical shift. The digital vertical lens shift has at maximum the 15% of
regulation, without loose in image resolution. The vertical optic lens shift reduces this
value.
The Lens Memory Save menu give you the possibility to store ten different configura-
tion of Zoom&Focus& Image Shift. Similarly, in the Lens Memory Load menu there are
ten different recall configurations: they are disabled until you will saved one. The
number of enabled memories, in the Load menu, corresponding to the number of
filled memories in the Save menu.
The F1, F2 and F3 buttons function, in the RC, have the possibility to recall one of the
first three Zoom&Focus&Image Shift memories.
