Throw distance and screen size
Seven separate bayonet style lenses can be used on this projector. Refer to the information on this page and use a
lens suited for the installation environment (screen size and throw distance). For installation and replacement of lens
units contact your distributor.
Each number provided in the table below means the throw distance between the lens surface and the screen.

TIP
• Calculation of the throw distance from the screen size
L2K-10F1 lens throw distance (m) = H × 0.93 : 78.7"/2.0 m (min.) to 822.8"/20.9 m (max.)
L4K-11ZM lens throw distance (m) = H × 1.24 to H × 1.73 : 105.9"/2.7 m (min.) to 1531.5"/38.9 m (max.)
L4K-15ZM lens throw distance (m) = H × 1.52 to H × 2.10 : 131.2"/3.3 m (min.) to 1866.1"/47.4 m (max.)
L4K-20ZM lens throw distance (m) = H × 1.98 to H × 3.34 : 185.0"/4.7 m (min.) to 2944.9"/74.8 m (max.)
L2K-30ZM lens throw distance (m) = H × 2.71 to H × 3.92 : 232.3"/5.9 m (min.) to 3484.3"/88.5 m (max.)
L2K-43ZM1 lens throw distance (m) = H × 3.91 to H × 5.52 : 338.6"/8.6 m (min.) to 4893.7"/124.3 m (max.)
L2K-55ZM1 lens throw distance (m) = H × 4.99 to H × 7.82 : 433.1"/11.0 m (min.) to 6937.0"/176.2 m (max.)
“H” (Horizontal) refers to the screen width.
* Figures differ by several % with the table above because the calculation is approximate.
Ex.: Throw distance when projecting on a 300" screen using the L4K-15ZM lens:
According to the “Tables of screen sizes and dimensions” in case of 4096 × 2160 (Aspect Ratio 17:9) ( → page 149 ), H (screen
width) = 265.4"/6.74 m.
The throw distance is 265.4"/6.74 m × 1.52 to 265.4"/6.74 m × 2.10 = 403.41"/10.24 m to 557.34"/14.15 m (because of the zoom
lens).
