are greatly reduced by FUJINON’s multi-layer EBC (Electron Beam Coating) lens coating. Breathing (an unwanted change in image size when focusing) has been minimized, as has color fringing, through the use of extraordinary dispersion glass. Lightweight zooms are also becoming popular for 3D applications. Having a zoom instead of a prime lens on a 3D rig allows easy adjustment of focal length without time- consuming lens changes, rig readjustments and calibration. Since 3D rigs are inherently cumbersome affairs, regular studio zooms tend to be too large and heavy, whereas the lightweight Alura Zooms are ideal. In addition, their compatibility with the ARRI Lens Data System allows vital lens information and image metadata to be recorded.
