Chapter 2 Getting Started — Setting upENGLISH - 41Formula to calculate projection distance per projection lensTo use a projected image size not listed in this manual, check the projected image size SD (m) and use the respective formula to calculateprojection distance.The unit of all the formulae is m. (Values obtained by the following calculation formulae contain a slight error.)When calculating a projection distance using image size designation (value in inches), multiply the value in inches by 0.0254 and substitute itinto SD in the formula for calculating the projection distance.For PT-RZ670r Standard zoom lensProjection lens Model No. Throw ratio Aspect ratio Projection distance (L) formulaMin.
