The high-end DLA-NZ9 (RS4100) is equipped with an 18-element, 16-group all-glass lens featuring a full aluminium lens barrel*1. To project highresolution 8K images to every corner of the screen, the projector incorporates five ED lenses calibrated for differences in the R/G/B refractive index to reduce chromatic aberration and colour fringing when lens shift kicks in to deliver precise reproduction of 4K- or 8K-resolution*2 projection.
