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. The binocular has the Bakelite dark brown rain cover. On the top case are embodied swastika and letters ‘K’ and ‘M’. Two pockets for filters are fitted into the case cover. 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. The original black leather case with embodied ‘E.Leitz Wetzlar’ logo and 1939 year. Lens hoods are more prominent in long focus lenses because they have a smaller viewing angle than that of wide-angle lenses. 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. 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.

All this makes the 28mm ELMARIT-R f/2.8 one of the most important working lenses, not just for the professional but for the amateur as well.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.

With bright light sources in the image field - still at full aperture. The lens is, therefore, outstanding for available light photography and for shots In color shots this means more saturated colors and greater color differentiation in the shadows. The system shows remarkable freedom from flare to yield brilliant and irradiation-free images even with high contrast subjects. And its remarkable freedom from vignetting (for an angle of this order) makes the 28mm ELMARIT-R an excellent lens for wide-angle color photography. The extreme angle of view with high speed and outstanding performance at full aperture make this lens particularly suitable for all these applications. It is of special value for feature photography in confined spaces - indoors or out - for architectural photography and for unusual perspective effects in creative publicity. Image definition is excellent over the whole field and the lens reaches its optimum performance at f/4 to 5.6 for distances between infinity and 3.5'. It is only a little over 1.5" long and weighs only 9.25 ozs. This new ultra-wide angle lens for the LEICAFLEX is not only exceptionally fast for its focal length, but also unusually compact.
