D-10 Vicon MX Hardware System Reference
Table D-6 lists the image circle diameter produced by the C-mount
lens formats (1", 2/3", and 1/2") and the 35 mm SLR format lens
appropriate for use with Vicon cameras.
Table D-7 lists the necessary image circle diameter for each
MX Camera at maximum resolution.
By comparing the image circle details in these two tables, you can use
the information in the following sections to select a lens capable of
producing the image circle diameter required for the specified type of
MX Camera. For example, you can see from the tables above that no
C-mount lens format projects an image circle large enough to fully use
the sensor in an F40, MX40+, MX40, MX13+, or MX13 camera.
A 2/3" C-mount sensor format is appropriate for an F20 or MX20+
camera, and a 1/2" C-mount sensor format is appropriate for an
MX3+ or MX3 camera.
For the larger format F40, MX40+, MX40, MX13+, or MX13 cameras,
SLR format lenses are more suitable than C-mount lenses. SLR lenses
are designed for use with 35 mm film, or equivalent digital sensors.
This format projects a larger image circle than C-mount lenses. As you
can see from the tables above, lenses designed for these formats
