Computar APC 25mm f/1.3 C Mount CCTV TV Movie Cinema Cine Lens (New in Box)

The Computar APC 25mm f/1.3 lens is a C-mount lens designed primarily for use in CCTV, TV production, movie, and cine applications. Here's what you need to know about it:

1. Focal Length and Aperture: The lens has a fixed focal length of 25mm, providing a moderately wide-angle view suitable for various shooting situations. The fast maximum aperture of f/1.3 allows for excellent low-light performance and shallow depth of field, making it versatile for various lighting conditions and achieving selective focus effects.

2. C-Mount Compatibility: The lens features a C-mount, a standard type of lens mount used in CCTV cameras, machine vision systems, and some compact mirrorless cameras. This makes it compatible with a wide range of camera systems, including those with smaller sensors like micro four-thirds.

3. Manual Focus: Like many C-mount lenses, the Computar APC 25mm f/1.3 lens typically features manual focus. This allows for precise control over focusing, but it requires adjusting the focus ring on the lens itself.

4. Compact Design: The lens is usually compact and lightweight, making it suitable for use in compact camera setups, such as surveillance cameras or smaller filmmaking rigs.

5. Image Quality: The lens is capable of producing sharp images with good contrast and minimal distortion, particularly when stopped down from the maximum aperture. However, wide open at f/1.3, it may exhibit some softness towards the edges of the frame, common with fast lenses.

6. Applications: Due to its moderate wide-angle view and fast aperture, this lens is suitable for various applications, including surveillance, security systems, machine vision, and filmmaking.

7. Adaptability: While designed for C-mount cameras, the lens can be adapted to fit a range of camera systems with the appropriate adapter, expanding its versatility for photographers and videographers.

8. Build Quality: Computar lenses are generally well-built and durable, designed to withstand regular use in industrial and professional environments.
