Arri Alura 15.5-45mm T2.8 Lightweight Zoom Lens - Feet

PL Mount Zoom Lens (Feet Scale)

Continuing its close collaboration with Fujinon, ARRI is adding two new lightweight lenses to its popular line of modern zooms: the ARRI/FUJINON Alura 15.5-45/T2.8 and the ARRI/FUJINON Alura 30-80/T2.8.

Both share the unique characteristics that have made the existing Alura studio zooms (18-80/T2.6 and 45-250/T2.6) already best-sellers: highest optical quality in a robust housing at an affordable price. While optimized for digital cameras, they are compatible with film cameras and include the ARRI Lens Data System (LDS).

Lightweight & compact

• For handheld, Steadicam and 3D rigs

ARRI Lens Data System

• Automatically provides lens metadata
• Increases efficiency of VFX and 3D post

Outstanding optical performance

• High resolution for 2K to 4K+ camera outputs
• High contrast through minimized flares and veiling glare (FUJINON multi-layer EBC coating)
• Greatly reduced chromatic aberration through the use of extraordinary dispersion glass
• Large image circle of 31.5 mm covers all current digital cameras
• Low geometric distortion and even field illumination
• Minimized breathing, especially at the wide end, where it counts
• Nine iris leaves for round, out-of-focus highlights and a pleasing, organic bokeh
• Consistent contrast, resolution and field illumination across the whole focus and zoom range
• Matched to all other ARRI zoom and prime lenses

Film Style Ergonomics

• Robust construction
• Large, easy-to-read precision focus scales on both sides
• Matching focus, zoom and iris scale positions
• 114 mm front diameter (like Master Primes)

Easy Servicing

• Feet/meter focus scales can be exchanged
• Zoom centering mechanism

• High resolution, high contrast
• Even field illumination
• T2.6 Consistent aperture over entire zoom range
• Minimized breathing, especially at the wide end where it counts
• 9 iris leaves for round, out-of-focus highlights and a pleasing, organic bokeh
