Middle Throw Zoom Lens (V12H004M01)
Image size: 60 to 600 inches (1.52 to 15.24 m)
Projection distance (focal range): 114 to 1791 in. (2.90 to 45.49 m)
■ To find the image size when you know the projection distance:
Maximum diagonal size = (0.5055 × projection distance) + 2.7
Minimum diagonal size = (0.3340 × projection distance) + 1.8
■ To find the projection distance when you know the image size:
Maximum projection distance = (2.9941 × diagonal size) – 5.3
Minimum projection distance = (1.9782 × diagonal size) – 5.3
