Description
Eliminate blind spots and conquer challenging low-light environments with our professional-grade 2MP 2.8mm CS-Mount Fixed Focal Lens. Specifically optimized for mainstream 1/2.7″ image sensors (such as the OmniVision OV2715), this high-performance Wide Angle Lens captures a sweeping 139° diagonal field of view, making it an excellent standalone solution for large-area monitoring. Engineered with an ultra-bright F1.2 aperture, it gathers maximum light to deliver crisp Full HD 1080P imagery even in near-pitch-black conditions. Combined with advanced IR Corrected optics that prevent focus drift during night vision transitions, this Fisheye Lens stands out as a dependable, budget-friendly asset for extensive CCTV Lens grids, rugged Industrial Lens setups, and heavy-duty Automotive Lens blind-spot integrations.
Key Highlights & Advantages
- 139° Sweeping Panoramic View: The ultra-short 2.8mm focal length yields a wide 139° diagonal and 116° horizontal coverage, allowing a single camera to replace multiple narrow lenses in tight or sprawling spaces.
- Ultra-Bright F1.2 Aperture: Maximizes light intake on 1/2.7″ sensors, drastically reducing digital image noise in low-illumination environments and keeping colors vivid longer before switching to night mode.
- Day/Night Optimized IR Correction: Advanced anti-reflective coatings force both visible and near-infrared wavelengths onto the exact same sensor plane, ensuring razor-sharp 2MP resolution 24/7 without manual focus adjustments.
- 0.3m Minimum Object Distance (M.O.D.): Supports crystal-clear macro focus as close as 30cm, making it ideal for close-range visual inspections and near-field obstacle detection.

Applications & Compatible Equipment
Core Application Scenarios
This fast-aperture Fixed Focal Lens is purpose-built for comprehensive perimeter protection and extreme low-light situational tracking. It excels as a 1080P industrial CCTV Lens for wide-area indoor monitoring in retail stores, banking lobbies, corridor intersections, and parking garage entrances where uneven lighting poses a constant problem. Its robust mechanics also qualify it as a dependable Automotive Lens asset for commercial transport cabin surveillance, heavy machinery rear-view tracking, and logistics truck blind-spot detection systems. Additionally, with its short 0.3m M.O.D., it functions excellently as an Industrial Lens inside compact automation enclosures to monitor wide conveyor fields or entry gates from close distances.

Frequently Asked Questions
Q: Will the 2.8mm focal length introduce significant barrel distortion?
A: Yes, a 2.8mm lens naturally introduces a curved visual perspective, characteristic of a wide-angle Fisheye Lens. For tracking and security deployments, this layout is preferred as it maximizes coverage area; if required, the distortion can be corrected via camera-side software dewarping.

Q: What is the benefit of an F1.2 aperture compared to standard F2.0 lenses?
A: An F1.2 aperture allows significantly more light to strike the 1/2.7″ sensor. This results in much brighter images, less electronic gain noise, and clearer color details in dark environments before the camera needs to switch on its IR illuminators.

Q: Does this lens require focus adjustments when night-vision IR activates?
A: No. Being an IR Corrected Lens means its glass elements focus both visible and infrared light onto the exact same sensor plane, eliminating focus shift and keeping your 2MP feed sharp 24/7.

Q: Can I use this 1/2.7″ lens on a larger 1/1.8″ format sensor?
A: No. Using a 1/2.7″ lens on a larger 1/1.8″ sensor will cause heavy vignetting (black circular corners) because the lens’s optical light circle is too small to cover the larger sensor surface.

Q: Can this CS-mount lens be directly threaded into an M12 board camera?
A: No, this is a native CS-Mount Lens. Its physical thread diameter and back focal distance require a standard CS camera body; it cannot fit directly onto miniature M12 camera modules without an external chassis adaptation.

Q: Is the manual focus mechanism secure enough for high-vibration automotive use?
A: Yes, the manual focus ring includes an industrial locking screw. Once you adjust and tighten the mechanism during initial setup, it easily withstands the constant vibration of commercial trucks or transit vehicles without drifting.
