Hanwha SLA-C-E2470 Canon EF 24-70mm f/2.8L II Lens

Hanwha SLA-C-E2470 Canon EF 24-70mm f/2.8L II USM Lens

The Hanwha SLA-C-E2470 is a professional-grade zoom lens engineered for seamless integration with the Hanwha TNB-9000 camera system. This Canon EF-mount lens delivers exceptional optical performance and flexibility for demanding surveillance applications across commercial, industrial, and urban environments. The 24-70mm focal range combined with a constant f/2.8 aperture provides operators with the versatility to capture both wide-area monitoring and detailed close-ups without compromising image quality.

Key Features

• Versatile Focal Range: 24-70mm zoom enables seamless transition from wide-angle to telephoto coverage
• Constant f/2.8 Aperture: Maintains consistent light transmission and exposure across all zoom levels
• Low-Light Performance: Wide aperture ensures clear image capture in challenging lighting conditions
• Ultra-Low Dispersion Optics: Advanced optical design minimizes chromatic aberrations and color fringing
• Aspherical Elements: Reduces optical distortion for sharp, high-contrast imagery
• Ultrasonic Motor (USM): Delivers fast, silent, and precise autofocus operation
• Advanced Lens Coatings: Multi-coated surfaces reduce flare, ghosting, and reflections
• Robust Construction: Built for durability in demanding security deployment environments

Technical Highlights

Canon's optical engineering delivers superior image quality through the combination of ultra-low dispersion glass and aspherical lens elements that work together to eliminate optical aberrations across the entire zoom range. The constant f/2.8 aperture ensures that exposure and depth-of-field remain consistent whether monitoring at 24mm or 70mm, eliminating the variability often seen with variable-aperture zoom lenses. The Ultrasonic Motor provides near-silent autofocus operation critical for covert surveillance applications, while advanced multi-coatings ensure clarity even when capturing scenes with bright backlighting or complex lighting geometry.

Integration & Applications

Purpose-built for the TNB-9000 camera platform, this lens provides mission-critical reliability for 24/7 security operations. Ideal for monitoring expansive areas such as retail spaces, manufacturing facilities, parking structures, and perimeter security while maintaining the ability to capture fine detail on demand. The 24-70mm range eliminates the need for lens changes in fixed-installation scenarios, reducing downtime and operational complexity. Professional surveillance teams rely on this lens for applications requiring both situational awareness and forensic-level image capture.

The SLA-C-E2470 represents a significant step forward in surveillance lens technology for the TNB-9000 platform. The constant f/2.8 aperture is a critical differentiator—most surveillance zoom lenses sacrifice light transmission at longer focal lengths, but this lens maintains full aperture performance across the entire 24-70mm range. This means operators achieve consistent image brightness and depth-of-field control whether monitoring wide areas or zooming in for detail verification.

The optical design's use of aspherical elements and ultra-low dispersion glass is particularly valuable in environments with harsh lighting conditions, where chromatic aberration can degrade evidence quality. Canon's proven USM technology ensures responsive autofocus without the acoustic signature of mechanical focus motors, important for installations where audible operation could compromise security or user experience. For organizations investing in TNB-9000 systems for high-stakes security operations, this lens delivers the optical performance and reliability required for mission-critical deployments.
