Two Lenses for All Formats

Two dedicated prime lenses are available for the HD-IVS and should be available in each rental house

to cover all shooting formats. The 4:3 lens is optimized for taller aspect ratios such as Super TV and

anamorphic formats. The entire 4:3 ground glass image is displayed on an HD monitor at 1440 x

1080 pixel resolution, leaving black vertical bars to the left and right. These black bars optionally

display metadata or the on-screen menu.

The 16:9 lens is optimized for aspect ratios of 16:9 or wider. A 16:9 aspect ratio image from the

ground glass is displayed on an HD monitor at 1920 x 1080 pixel resolution. While this would cut into

the image of tall formats such as Super TV or anamorphic (see orange lines in the image below), it is

perfect for wider formats such as HDTV or 1.85:1.

The use of two prime lenses ensures that the maximum aperture is maintained at all times, which would

not be possible with a zoom lens. The two prime lenses can be exchanged by the camera rental house.
