Cosmicar/Pentax 12mm f1.2 C Mount Lens (Pre-owned)

The Cosmicar/Pentax 12mm f/1.2 lens is a compact C-mount lens designed for various applications, including surveillance, machine vision, and micro-four-thirds camera systems. Here's what you need to know about it:

1. Focal Length and Aperture: The lens has a fixed focal length of 12mm, providing a wide-angle view suitable for capturing expansive scenes. The fast maximum aperture of f/1.2 allows for excellent low-light performance and shallow depth of field, making it versatile for various lighting conditions.

2. C-Mount Compatibility: The lens is designed with a C-mount, a standard type of lens mount used in surveillance cameras, machine vision systems, and some compact mirrorless cameras. It's important to note that while it's designed for C-mount, it can be adapted to micro four-thirds or other camera systems with the appropriate adapter.

3. Manual Focus: Like many C-mount lenses, the Cosmicar/Pentax 12mm f/1.2 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 compact and lightweight, making it suitable for use in compact camera setups, such as surveillance cameras, or for attaching to smaller camera systems.

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/1.2, it may exhibit some softness towards the edges of the frame, common with fast lenses.

6. Applications: Due to its wide-angle view and fast aperture, this lens is suitable for various applications, including surveillance, security systems, astrophotography, landscape photography, and even creative filmmaking.

7. Adaptability: The lens can be adapted to fit a range of camera systems, making it a versatile option for photographers and videographers looking for an ultra-wide-angle lens with a fast aperture.

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