5.3 Touch Screen Operation
All three IQ models incorporate a newly-designed 3.2 inch touch screen.
The screen lets you zoom, pan and browse through images fast and it is
easy to navigate between dierent menus and features. The IQ series backs
are designed with invisible controls that are context sensitive and appear
only when specic areas of the screen are touched. One example of this is
the unique instant zoom function, which allows you to zoom just by using
one nger. Small histograms and highlight warnings can be enlarged to full
screen view by simply touching them. Wide format display allows for a full
4:3 aspect ratio VGA resolution image next to histogram, highlight warning,
focus mask, EXIF data and touch controls. It is possible to operate the IQ
back using the touch screen display or the well-known and intuitive 4-but-
ton navigation.
