Notes:
1. Throw distance does not affect image quality, provided these ranges are taken into account.
2. Only the Signature C, D, E, F and G lenses can be used with the optional CineWide (secondary
anamorphic) lens. Doing so affects the throw distances as shown here.
3. The “1.90:1” throw distances are for reference only. The SC-1 has a native resolution of 2048 x
1080, which is about a 1.90:1 native aspect ratio. With most source material, the SC-1 only uses
the center, 1,920 pixels in each row (1920
x 1080 = 16:9 or 1.78:1 native aspect ratio).
