The camera is an important tool for us to record and convey the world, and the lens is the core component of the camera. The camera lens captures light and transforms the scene into an image, becoming a medium for the camera to interact with the outside world. Regarding SONY’s new FCB-EV9520L lens, we will introduce its functions, types and applications.
The role of the lens
The camera lens is a medium that converts external scenery into images. It focuses and adjusts light so that the camera can accurately capture the world it sees. The quality and characteristics of the lens directly affect the image clarity, color reproduction, viewing angle and depth of field. It is an important tool for the camera to interact with the outside world. SONY FCB-EV9520L adopts a 30x optical zoom and 12x digital zoom lens. With the optical zoom, the digital zoom is 360x.
Type of lens
Common lenses for cameras include the following types:
- Fixed focus lens: The focal length of a fixed focus lens is fixed and cannot be adjusted. It usually has high optical quality and a large aperture, and is suitable for shooting scenes that require high image quality and a large aperture, such as portraits, product photography, etc.
- Zoom lens: The zoom lens can adjust the focal length to adjust the distance of the target. It can switch between distant view and close-up view without changing the position. The advantage of a zoom lens is its flexibility, which is suitable for capturing scenes with diverse picture compositions, such as drone pods, ocean operations, etc. SONY FCB-EV9520L uses a variable-focus lens with a focal length of f= 4.3 mm – 129 mm, which can achieve a wider range of zoom to suit different industry needs.
- Wide-angle lens: A lens with a viewing angle of more than 90 degrees is called a wide-angle lens. It has a larger viewing angle and can capture a wider scene. It is suitable for scenes that require a wide field of view. The horizontal field of view of the SONY FCB-EV9520L can reach up to 64 degrees. Although it is still far behind the wide-angle lens, the field of view is much better than the standard lens.
- Telephoto lens: The telephoto lens has a longer focal length and can magnify distant targets and capture distant scenery. It is suitable for scenes that require a closer distance, such as wildlife photography, sports events, etc.
Security surveillance: FCB-EV9520L 30x optical zoom lens can achieve smooth zoom from wide angle to telephoto, capture targets from long distances, and provide clear, detailed images. This makes it very suitable for use in surveillance and security fields, such as large buildings, city surveillance, traffic monitoring, etc.
Drones: The 30x optical zoom lens of the FCB-EV9520L has a lightweight and compact design and is suitable for use in drone aerial photography, surveying, mapping, and inspections. Its high-magnification optical zoom capability can capture long-distance scenery and provide stable and clear images, making drone aerial photography, surveying and inspection more advantageous and practical.
Video conferencing and remote education: The autofocus and auto-exposure functions of the FCB-EV9520L 30x optical zoom lens can automatically adjust the focus and exposure setting according to the shooting environment, ensuring that images in video conferencing and distance education are always clear and bright. Its high resolution and clarity can provide lifelike images, making remote communication more realistic and efficient.
Marine operations: FCB-EV9520L 30x automatic zoom lens can capture marine life, vegetation and geological features from a long distance and provide clear, detailed images to help scientists and researchers observe, record and analyze.
Automation and machine vision: The 30x optical zoom lens of FCB-EV9520L can be connected to other equipment through electronic interfaces, such as machine vision systems, automation control systems, etc. It can provide high-quality image input, help machine vision systems achieve accurate identification and detection, and improve the efficiency and accuracy of automated production and control.
Camera lenses are an integral and important part of the photography process. Different types of lenses can meet different user needs. For example, fixed focal length lenses are suitable for high image quality needs, zoom lenses are suitable for diverse picture compositions, wide-angle lenses are suitable for showing a wide field of view, and telephoto lenses are suitable for capturing long-distance targets. Choosing the right camera lens requires comprehensive consideration of factors such as focal length, aperture, optical quality, brand and price.
