ARRI-ALURA-LIGHTWEIGHT-ZOOM-15.5-45-T2.8-F

Alura Lightweight Zooms

Both, the ARRI Alura 15.5-45/T2.8 and the ARRI Alura 30-80/T2.8 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).

Features

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

The Lightweight Aluras were the only lenses I needed.

What I love about the 15.5-45 Alura is its versatility. The LDS feature is particularly useful when I'm shooting VFX work.
