5.5mm-82.5mm f1.8 TV Zoom Lens C Mount Cine TV Lens

The 5.5mm-82.5mm f/1.8 TV Zoom Lens is a versatile C-mount lens designed primarily for use in television production, but it can also be adapted for other purposes such as filmmaking, surveillance, or even astrophotography. Here's what you need to know about it:

1. Zoom Range: The lens features a zoom range from 5.5mm to 82.5mm, providing a wide range of focal lengths suitable for various shooting situations. This allows you to adjust the framing and composition without changing lenses, making it convenient for capturing different scenes.

2. Aperture: With a maximum aperture of f/1.8, the lens offers excellent low-light performance and the ability to achieve shallow depth of field, especially at shorter focal lengths. This makes it suitable for shooting in dimly lit environments or achieving selective focus effects.

3. C-Mount Compatibility: The lens is designed with a C-mount, a standard lens mount used in surveillance cameras, machine vision systems, and some compact mirrorless cameras. While it's primarily designed for C-mount cameras, it can be adapted to fit other camera systems with the appropriate adapter.

4. Manual Focus and Zoom: Like many C-mount lenses, this lens likely features manual focus and zoom control. This allows for precise adjustments to focus and focal length, giving the photographer or videographer full control over the image.

5. Compact and Lightweight: Despite its zoom capability, the lens is typically compact and lightweight, making it suitable for use with smaller cameras or setups. This makes it a practical choice for portable or handheld shooting.

6. 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, image quality may vary across the zoom range, with some loss of sharpness or vignetting at extreme focal lengths.

7. Versatility: The wide zoom range and fast aperture make this lens versatile for a range of applications, including television production, documentary filmmaking, surveillance, and more. It can be used for capturing everything from wide establishing shots to close-ups with shallow depth of field.

8. Adaptability: With the appropriate adapter, the lens can be mounted on various camera systems, expanding its compatibility beyond C-mount cameras.
