Notes:
1. Throw distance does not affect image quality, provided these ranges are taken into account.
2. Only the Proteus 2, 3, 4, 5 and 6 lenses can be used with the optional CineWide (secondary
anamorphic) lens. Doing so affects the throw distances as shown here.
3. The Proteus 2, 3 and 4 lenses cannot be used with the small (3.82 cylindrical, aka “Rainier”)
anamorphic lens.
