Axis 5800-791 Computer CCTV Lens – Black

The Axis 5800-791 is a high‑performance telephoto zoom lens designed specifically for Axis IP cameras that use the CS mount. With its compact form factor and robust optical construction, this lens delivers exceptional image quality across a wide range of surveillance scenarios.

Key Optical Specifications

Aperture: f/1.4 – provides a bright entrance pupil for low‑light performance and shallow depth of field control.
Focal Length Range: 12.5 mm to 50 mm – a 4× optical zoom that allows operators to switch from wide‑angle coverage to tight framing without digital interpolation.
Maximum Focal Length: 50 mm – ideal for long‑range monitoring, such as perimeter or vehicle tracking.
Minimum Focal Length: 12.5 mm – offers a generous field of view for broader area coverage.
Sensor Size Compatibility: 1/3" (3.0 mm) – matches the sensor format used in many Axis P1353, P1354, Q1602, and Q1604 series cameras.
Optical Zoom: 4× – ensures crisp detail at both ends of the zoom range.

Mechanical Design & Mounting Interface

The lens features a 46 mm diameter barrel and a total length of 58 mm, making it lightweight yet sturdy. It is engineered for the CS mount, which is standard on Axis’s P1353, P1354, Q1602, and Q1604 camera families. The black case color provides a neutral aesthetic that blends seamlessly with most installation environments.

Performance Highlights

Wide Aperture (f/1.4): Enables superior low‑light performance, reducing motion blur and improving image clarity in dim conditions.
High‑Quality Lens Elements: Constructed from premium optical glass to minimize distortion, chromatic aberration, and vignetting across the zoom range.
Auto‑Iris Functionality: The DC‑iris mechanism automatically adjusts the aperture based on lighting conditions, maintaining optimal exposure without manual intervention.
Consistent Image Quality: Maintains sharpness and color fidelity from wide to telephoto settings, ensuring reliable video analytics and facial recognition accuracy.

Installation & Compatibility

The Axis 5800-791 is a drop‑in replacement for the original lens on compatible cameras. Installation requires only the standard CS mount interface; no additional adapters or modifications are necessary. Once mounted, the lens automatically communicates with the camera’s firmware to enable full zoom and iris control.

Use Cases

Perimeter Security: The long‑range capability allows monitoring of fences, gates, or parking lots from a single point.
Vehicle Tracking: High magnification and low aperture provide clear identification of license plates even at night.
Crowd Management: Wide‑angle mode captures large crowds while the telephoto setting can isolate individuals for detailed observation.
Retail Surveillance: The lens’s versatility supports both broad store coverage and focused monitoring of high‑value areas.

Key Features
Aperture The f‑number (aperture value) of a camera lens or optical system, indicating the size of the aperture opening. It determines how much light enters the sensor and affects depth‑of‑field. Values are typically expressed as a numeric value prefixed with "F" (e.g., F1.2, F2.8) or as a single numeric value when the "F" is omitted.	1.4
Case colour The colour or combination of colours that a product’s outer shell or enclosure is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the case for consumers.	Black
Diameter The linear measurement across a circular or round object, taken through its center. It is expressed in units of length such as millimeters, centimeters, inches, or feet and represents the widest span of the item.	46 mm
Form factor Specifies the physical configuration or design of a product, such as ATX, Micro‑ATX, Mini‑ITX, tower, case with cover, etc. It describes how the device is built and what mounting or expansion options it supports.	Lens
Harmonized System HS code The Harmonized System (HS) code is a standardized numerical identifier used internationally to classify traded goods. It consists of up to six digits, where each pair of digits represents progressively more specific product categories. The HS code facilitates customs duties, trade statistics, and regulatory compliance by providing a common language for describing products across borders.	90021100
Height The vertical dimension of a product measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and applies to any item where height is relevant, including books, electronics, furniture and other objects.	58 mm
Lens type The classification of a camera lens, indicating its optical design and intended use such as prime, zoom, wide‑angle, telephoto, macro or specialty types (e.g., fisheye, polarizing). It helps buyers understand the lens’s focal range, aperture characteristics, and typical shooting scenarios.	Zoom
Maximum focal length The longest focal distance that a lens or optical system can achieve, expressed with a length unit such as millimetres (mm), centimetres (cm) or inches (in). It indicates the maximum field‑of‑view angle and zoom capability of the device.	50 mm
Minimum focal length The shortest focal distance that a lens or optical system can focus on, expressed with a length unit such as millimetres (mm), centimetres (cm) or inches (in). It indicates the widest field‑of‑view angle and is useful for understanding the camera’s ability to capture wide scenes.	12.50 mm
Optical zoom The multiplier that indicates how many times an image or field of view is enlarged by the optical system of a camera, lens or other imaging device. The value is expressed as a plain number with an optional "x" suffix (e.g., 2x, 5x). It represents the ratio between the magnified and the original size and does not include digital zoom effects.	4x
Pack quantity The total number of individual units contained within a single package or bundle. This value helps customers understand how many pieces they receive when purchasing the product, and it is useful for inventory, shipping, and comparison purposes.	1
