In the current booming live streaming industry, the choice of repair lens is crucial, which directly affects the clarity and texture of the live streaming picture. Phonefix is well aware of this. Next, Phonefix will share with you how to accurately select high-quality lenses that meet the repair needs of the industry camera from a wide range of Live Streaming Lenses, so as to help the repair process be clearly displayed and the live streaming effect be taken to a higher level.
Related factor to consider:
Lens Mount: The lens mount is crucial for the application of live broadcast lenses. It not only affects the image quality, but also ensures the compatibility of the camera and lens, thereby ensuring the stability of the system and image clarity.
Common mounts in industrial cameras include:
C-Mount/CS-Mount: C-Mount: 17.526 mm flange distance. CS-Mount: 12.5 mm flange distance. These are the most prevalent standards for industrial and machine vision cameras. They share the same thread, but have different flange focal distances (the distance from the mounting flange to the sensor). A C-mount lens can be used on a CS-mount camera with a 5mm adapter ring. However, a CS-mount lens cannot be used on a C-mount camera.
S-Mount (M12): A smaller, board-level mount often used in compact or embedded cameras. It offers a wide variety of lens options, from fisheye to telephoto.
F-Mount: A bayonet-style mount originating from Nikon, used for larger sensors and high-resolution applications that demand superior image quality.
Sensor Size: Sensor size plays a key role in the live lens of industrial cameras. A larger sensor size can capture more light and details, improving image quality. At the same resolution, a larger sensor area can provide a larger unit pixel area, improving photosensitivity and imaging effects. In addition, sensor size also affects the field of view. For larger sensors, using a fixed magnification lens can achieve a wider field of view.
Focal Length: Focal length is measured in millimeters (mm) and determines the viewing angle and magnification.
Short focal length (e.g. 4 mm): Provides a wide field of view. Ideal for monitoring wide areas such as a production line, an entire room, or a wide conveyor belt.
Long focal length (e.g. 25 mm, 50 mm): Provides a narrow and magnified field of view. Ideal for inspecting fine details on a specific part, monitoring a distant process, or reading a meter at a distance.
Varifocal lenses: Available in a range of manually adjustable focal lengths (e.g. 5-50 mm). This provides flexibility during setup to build the perfect shot.
Varifocal lenses: Similar to zoom lenses, but are "parfocal" lenses, meaning they maintain focus even as focal length changes. Powered zoom lenses are ideal for live broadcasts where the field of view needs to be changed remotely.
Aperture (F-stop): Aperture is measured in f-stops. A lens with a large maximum aperture (low f-number) is critical for low-light industrial environments. It allows more light in, resulting in brighter, clearer images, and reduces digital noise.Depth of Field (DoF): This is the range of distances within a scene that appear acceptably sharp.
A large aperture (low f-number) produces a shallow depth of field, isolating a specific subject in focus.
A narrow aperture (high f-number) produces a deep depth of field, keeping both near and far objects sharp, which is often desired for general surveillance.
Lens construction quality: Live broadcast applications are often carried out in different environmental conditions, so the construction of the lens must be able to withstand vibration, shock, and dust. 2 Choose lenses that have been proven in industrial applications. For example, a lens with a metal housing may be more durable than a plastic housing.
Autofocus and stability: If the live broadcast requires moving lenses, autofocus functions and the stability design of the lens are equally important. This can help recorders keep the image clear and stable when the object is moving quickly.

Environmental factors:
Rugged: Look for lenses specifically labeled "industrial grade" or "rugged." With their metal housings and rugged construction, these lenses are built to withstand shock and vibration.
Focus and iris locks: Simple, yet critical features. Locking screws on the focus and iris rings prevent them from shifting due to machine vibrations, ensuring images are sharp and exposures are consistent.
High temperature resistance: Factories and outdoor facilities can experience dramatic temperature swings. Confirm the operating temperature range of the lens to ensure it will perform reliably in your specific environment.
Ingress protection (IP rating): If the lens will be exposed to dust or moisture, look for an IP rating that demonstrates its level of protection.
