Projection Lens

Projection lenses are a type of lens used in photography and cinematography to project images onto a screen or surface. They are commonly used in slide projectors, overhead projectors, and other projection systems.

In the context of the supply class "Photographic Equipment And Accessories" in the supply group "Photographic Equipment," projection lenses refer to the specific lenses designed for use in projection equipment. These lenses are typically designed to provide a sharp and clear image projection, with features such as adjustable focal length, aperture control, and image distortion correction.

Projection lenses come in various focal lengths and aperture sizes to accommodate different projection distances and lighting conditions. They are often interchangeable, allowing photographers and cinematographers to choose the most suitable lens for their specific projection needs.

When selecting a projection lens, factors such as the desired image size, projection distance, and the level of image quality required should be considered. Different projection lenses may have different characteristics, such as wide-angle or telephoto capabilities, which can affect the final projected image.

Overall, projection lenses are essential components of photographic equipment used for projecting images onto screens or surfaces, enabling photographers and cinematographers to share their work with others in a larger format.
