Notes:

1. Throw distance does not affect image quality, provided these ranges are taken into account.

2. Only the Proteus D, E and F lenses can be used with the optional CineWide (secondary anamorphic) lens. Doing so affects the throw distances as shown here.

Throw Ratio - Standard CL-810:The standard CL-810 offers a throw ratio of between 1.80 and 2.38.

Throw Ratio - Standard CL-810/CineWide: The standard CL-810/CineWide offers a throw ratio of between 1.90 and 2.38. It uses a prismatic-style anamorphic lens that compresses the image height (as opposed to the cylindrical anamorphic lenses used with the CL-810 Ultra, which stretch the image width).
