In addition, lens hoods can offer some degree of physical protection for the lens due to the hood extending farther than the lens itself. Lens hoods are often designed to fit onto the matching lens facing either forward, for normal use, or backwards, so that the hood may be stored with the lens without occupying much additional space. For wide angle lenses, the length of the hood cannot be as long as those for telephoto lenses, as a longer hood would enter the wider field of view of the lens. Lens hoods are more prominent in long focus lenses because they have a smaller viewing angle than that of wide-angle lenses. In August 2020, I was invited to the Leitz Lens Test & Summer BBQ, at Leitz Park in Wetzlar, Germany, and wanted to share my experience and some photographs with the readers of Cinematography World.
This allows the lens hood to block stray light with the higher portions of the lens hood, while allowing more light into the corners of the image through the lowered portions of the hood. DP Alexis Castagna takes a mouth-watering tour around Leitz’s lens factory. The geometry of the lens hood can vary from a plain cylindrical or conical section to a more complex shape, sometimes called a petal, tulip, or flower hood. This stray light often comes from very bright light sources, such as the sun, bright studio lights, or a bright white background. Flare occurs when stray light strikes the front element of a lens and then bounces around within the lens. *) Source of data: Scarce manufacturer's technical data + own research.Ī lens hood or lens shade is a device used on the end of a lens to block the sun or other light source in order to prevent glare and lens flare.
