Rainbow 4mm f1.4 TV Lens (IN BOX)

The Rainbow 4mm f/1.4 TV lens is a small, fixed focal length lens designed for use with television cameras or CCTV systems. Here's some information about it:

1. Focal Length and Aperture: The 4mm focal length provides an ultra-wide-angle view, while the fast f/1.4 aperture allows for good low-light performance and shallow depth of field.

2. Lens Mount: This lens typically comes with a C-mount, which is a common mount for CCTV and machine vision cameras. It's also adaptable to micro four-thirds and other mirrorless camera systems with the appropriate adapter.

3. Manual Focus: The lens usually has manual focus, meaning you have to adjust the focus ring on the lens itself to achieve sharp focus.

4. Fixed Aperture: It usually has a fixed aperture of f/1.4, which means you can't adjust the aperture. However, the wide aperture allows for creative depth of field effects and makes it suitable for low-light shooting.

5. Compact Design: The Rainbow 4mm f/1.4 TV lens is typically small and lightweight, making it suitable for use in compact camera setups or surveillance systems.

6. Field of View: With a 4mm focal length, the lens provides an extremely wide field of view, capturing a large area in the frame. This makes it suitable for surveillance applications or capturing wide scenes in TV production.

7. Image Quality: The image quality of this lens may vary, but generally, it's sufficient for its intended purpose, such as surveillance or monitoring systems. However, it may not offer the same level of optical quality or sharpness as more expensive lenses designed for photography.

8. Applications: This type of lens is commonly used in security cameras, monitoring systems, and industrial applications where a wide-angle view is needed.

9. Compatibility: While designed for television cameras and CCTV systems, the lens can also be adapted for use with mirrorless cameras, providing an ultra-wide-angle option for creative photography or videography.
