Check Out the Advantages of 4/3″ Format 12mm Fixed Focal Length Lens
Check out the fundamental benefits of a fixed-focal-length lens before planning to purchase from the best megapixel lens manufacturers:
- Floating Mechanism Design
The camera’s focal length remains fixed at 12mm. Generally, compact camera lenses with the same focal length promise improved image quality, larger apertures, and better image quality compared to zoom lenses.
- Extra Low Dispersion
The wide-band multi-coating on this lens helps to prevent glare and other reflections. It goes a long way in reducing color fringing, and images come out naturally sharp and well-balanced.
- Low Distortion
The lens design minimizes distortion. A straight line will appear straight, giving an image with a realistic look and high definition. Big Image A Φ23mm Large Image Format (C-mount) with a larger imaging area and perfect image compatibility with high-resolution sensors.
- Consistent Megapixel Resolution
The megapixel resolution remains consistent, even when the iris is fully open. It ensures that no corners are cut in images.
Key Features of 4/3″ Format 12mm Fixed Focal Length Lens
Let’s check out some fundamental features of the 4/3″ Format 12mm Fixed Focal Length Lens that you must know before purchasing from the megapixel CCTV lens manufacturers:
- Designing the Floating Mechan
The optical focal length of the camera is fixed at 12mm. The general purpose of compact cameras, regardless of focal length, is to deliver clearer images, larger apertures, and improved image quality than zoom lenses.
- Extra Low Dispersion
The wide-band multi-coating on this lens minimizes glare and other reflections. Nevertheless, this characteristic ensures minimal color fringing and that images are naturally sharp and balanced.
- High Maximum Aperture (Variable)
Although individual apertures vary by maker (for example, aperture values may be f/1.4, f/1.6, and so on for f/2.0), such lenses usually have a fixed maximum aperture.
- Low-light performance
- Shallow depth of field
- High Optical Quality
High megapixel camera lenses are designed with advanced optical components, such as extra-low dispersion (ED) and aspherical elements, to reduce aberrations, flare, and distortion.
- Low Distortion
Many 12mm lenses are designed for low distortion, ensuring that lines remain straight, which is particularly significant for architectural photography.
Camera & Sensor Compatibility Section of 4/3″ Format 12mm Fixed Focal Length Lens
4/3″ Format 12mm Fixed Focal Length Lens is designed for users of high-resolution industrial cameras. Nevertheless, this 12mm fixed-focus lens is based on a 4/3″ format and a C-mount. Fixed-focal lenses manufactured by leading megapixel lens manufacturers are easily compatible with any standard industrial camera, regardless of sensor size (4/3″, 1″, 2/3″, etc.). Additionally, because it has an image circle of 23mm, no corner darkening or loss of resolution occurs on a 4/3″ sensor.
However, fixed-focal-length lenses function effectively with typical global-shutter sensors, such as Sony IMX sensors, as well as with rolling-shutter sensors and high-resolution image sensors. They can be seamlessly connected with popular industrial cameras such as Hikvision, Dahua, or Uniview. Megapixel lens manufacturers ensure that the lenses’ effectiveness and efficiency will be evident in inspection systems, automation systems, and vision robots, with no performance degradation across varying image sensors.

Megapixel Lens Manufacturers
According to the above image, the mechanical drawing provided, the 4/3” format 12mm fixed focal length lens is designed for seamless and accurate integration with the industry. The lens length is 77.00mm, which is appropriate for mounting in even miniaturized automation systems. The size of the front lens is given as an outer diameter of Ø64.0mm, while for the camera-side mounting, the size is a diameter of Ø44.50mm, compatible with the standard camera mount arrangement.
However, this lens uses a standard C-mount thread 1″-32 UNF and has a back focus distance of 17.53 mm. Thus, it provides the best back focus positioning for an industrial camera. The manual focus and iris focus loops, as in the figure, along with the screws, keep the settings accurately positioned so that focus drift due to vibration or continuous operation does not occur.
