Zoom lens by ARRI and Fujinon with constant T-stop across the focal length range. Change focal length without losing light — the go-to choice for premium productions where consistency matters.
Definition
The ARRI/Fujinon Alura is a series of high-quality zoom lenses, born from the collaboration between European optics specialist ARRI and Japanese lens manufacturer Fujinon. This zoom series embodies the fusion of Japanese optical precision with European cinematographic demands, offering an excellent alternative to ultra-specialists like Variable Primes.
The Alura zooms are characterized by their wide zoom ratios, constant apertures, and a distinct, cinematic look that remains consistent across the entire zoom range. They are highly flexible and reliable – ideal for professional productions that demand both quality and practicality.
Technical Specifications
Focal Length Ranges
The Alura series includes several models with particularly wide zoom ratios:
- Alura 18-80mm (4.4:1 Zoom): Universal standard zoom from wide-angle to slight telephoto
- Alura 45-250mm (5.5:1 Zoom): Extended telephoto range for portraits and details
- Alura 18-250mm (13.8:1 Zoom): Ultra-variable super zoom element with an extreme zoom range
- Alura 8-80mm (10:1 Zoom): Specialty zoom with an extended wide-angle for architecture and landscapes
Aperture and Light Values
- Constant aperture: Typically T2.8 to T3.5 across the entire zoom range
- Some models can achieve T2.0 at mid-focal lengths
- Wide-angle models: T2.8 to T3.4
- Telephoto models: T3.5 to T4.5
- Minimum focus distances: 0.3-0.6 meters depending on the model
- Focus breathing: Significantly minimized through optical design
Optical Characteristics
- High-quality Fujinon glass formulations
- Multi-coating technology for flare reduction
- Compensated spherical and chromatic aberrations
- Natural vignetting (not corrected, but subtly utilized)
- Optimized bokeh characteristics with 8-10 iris blades
Use in High-End Productions
The ARRI/Fujinon Alura Zooms are ideal for:
Television series and streaming content: The wide zoom ratios allow for quick changes between different framing. Perfect for episodic storytelling under time pressure.
Documentaries and reality formats: The optical flexibility and reliability are essential for situations that cannot be repeated. Documentary cinematographers trust the consistency of these zooms.
Commercials and music videos: High-end commercials utilize the creative possibilities of wide zoom ratios in combination with professional optical quality.
Corporate and event production: For live broadcasts and event coverage, the Alura Zooms offer the right balance between flexibility and visual quality.
Arthouse and independent cinema: Directors with smaller budgets appreciate the optical quality at a lower cost compared to Variable Primes.
Premium Zooms vs. Prime Lenses
Why Premium Zooms like the Alura are Superior to Standard Zooms:
Optical Consistency: While standard zooms often exhibit light loss when zooming, Alura zooms offer consistently constant aperture and optical quality. This means no lighting re-adjustments during zoom moves.
Minimal Aberrations: Focus breathing when zooming is minimized. A focus puller can focus to infinity, and sharpness remains consistent at close distances when the focal length is changed.
"Kodak" Character: The Alura zooms produce a warmer, more "cinematic" look than many modern zooms – with soft bokeh and natural colors reminiscent of classic Kodak film stock.
Alura vs. Variable Prime:
| Feature | Alura | Variable Prime |
|---|---|---|
| Zoom Range | 4.4:1 - 13.8:1 (wider) | 2.5:1 - 5.5:1 (narrower) |
| Aperture | T2.8-T3.5 (good) | T1.9-T2.8 (better) |
| Focus Breathing | Minimal | Ultra-minimal |
| Optical Perfection | Very high | Ultra-high |
| Cost | Moderate rental | Premium rental |
| Practicality | Very high | High |
The Characteristic Look – Alura Aesthetics
The ARRI/Fujinon Alura Zooms have a recognizable, sought-after optical character:
Color Rendition: Warm and natural, with subtle golden tones in the highlights. Excellent color fidelity across all focal lengths, especially for skin tones.
Bokeh: Creamy, soft bokeh with a natural fall-off. The 8-10 iris blades create organic, smooth out-of-focus areas without a polygonal effect.
Contrast: Natural, balanced contrast without aggressively boosted midtones. The look feels cinematic, not digital.
Flare Character: Subtle, golden-warm lens flares when shooting into the light. This is a subtle design feature that makes the overall look warmer.
Sharpness Transition: Smooth, natural transition between in-focus and out-of-focus areas. No unnatural sharp edges or points.
Vignetting: Slight, natural vignetting, especially in the wide-angle range – subtle and not exaggerated, which frames the image.
Fujinon Heritage – Why Japanese Optics?
Fujinon has been legendary for broadcast zooms for decades. The collaboration with ARRI brought this proven optical engineering into the cinema sector:
- Precision Mechanics: Japanese manufacturing tradition with tight tolerances
- Glass Formulations: Proprietary Fujinon glass blends for warm, cinematic characteristics
- Reliability: Proven in broadcast environments, now optimized for cinema
Typical Production Workflows with Alura Zooms
Scene with Multiple Setups: A director can zoom from a wide shot (18mm) to a medium (35mm) to a close-up (80mm) within minutes without changing lenses – a gain in efficiency, especially in documentary shooting.
Live Components: For cinema with live elements or hybrid documentary approaches, Alura zooms offer the flexibility to react to unexpected moments.
Fast Dialogue Setups: In dialogue scenes, directors can quickly vary between different shot sizes without light loss, while the cinematographer remains focused.
Comparison to Other Zooms
vs. Standard Broadcast Zooms:
Alura offers higher optical quality, lower aberrations, and warmer colors. Standard broadcast zooms are more affordable but optically less refined.
vs. ARRI/ZEISS Variable Primes:
Variable Primes have narrower zoom ratios but higher apertures and ultra-minimal focus breathing. Alura zooms offer wider zoom ratios at moderately higher costs than standard zooms.
vs. Optimo Series (also Fujinon):
The older Optimo series was the predecessor. Alura improves the design with modern optical optimizations and slightly wider zoom ratios.
Conclusion
The ARRI/Fujinon Alura Zooms are the backbone of many professional cinema productions worldwide. They offer a balanced combination of flexibility (wide zoom ratios), optical quality (warm, cinematic, consistent), and practicality (reliable, easy to handle). They are ideal workhorse zooms for productions that require both quality and efficiency.
