Formed metal bellows are made from tubing by the application of internal pressure. The convolutions are formed in parallel planes that are perpendicular to the longitudinal centerline of the bellows. The tubing is normally made from sheet or coil that is rolled and longitudinally welded. Seamless tubing is available for smaller diameters.
The flexible element of an expansion joint consisting of one or more convolutions.
The center section (usually in large format cameras) which connects the front (lens) to the back (camera body). The bellows is made of leather, cloth or plastic, and is accordion-pleated for flexibility and is lighttight.
An expandable, flexible, light-tight, accordion-folded instrument used in view cameras to connect the lens to the film plane, as well as in other formats for close-up photography.
A corrugated cylindrical container which moves with a pressure change.
Bellows are a flexible piece of material similar to an accordion which is placed between the lens and the camera body usually mounted on a parallel rail system. The rails allow the bellows to be adjusted to change the distance between the lens and the body. This can be used to enable macro photography and close focusing. See also: Macro Photography
a closed vessel with sides that can expand and contract, like an accordion
a cylindrical device that is usually ribbed and very flexible
A device used for macrophotography. It allows you to vary the distance between the film plane and the lens so that the subject can be brought close to the lens. The bellows is attached to the camera body and the lens is attached to the other end of the bellows. You then move the lens back and forth until the subject is focused. Also a light tight, folding sleeve between the lens and the film plane on large format cameras and other cameras that have tilts and swings. See: Extension Tubes, and Reversing Ring.
Hollow flexible lightproof 'box' of pleated thin leather. Used to minimize weight and size in folding cameras.
A specialty accessory that allows you to focus very, very close to your subject. Expensive. Consider “ extension tubes” as a more affordable alternative.
A thin metal cylinder with convolutions. It is flexible and is used as part of flexible tube components.
The flexible element of bellows form in some types of water hammer arresters which separates the displacement cushion from the surge chamber.
Accordion-like device mounted on cameras that allows the lens to move towards or away from the film/sensor-plane for greater magnification than with the lens alone. Usually employed for close-up or macro work. Nikon bellows are the PB-3, PB-4, PB-5 and the latest model PB-6 which can be extended further for higher magnification with the PB-6E extension bellows.
A flexible, accordion-like seal used where angular or lateral motions require a large degree of movement.
An apparatus for producing air currents in certain wind instruments (accordion, bagpipe).
The bellows is the flexible element of an expansion joint. Formed metal bellows are made from tubing by the application of internal pressure. The convolutions are formed in parallel planes that are perpendicular to the longitudinal centerline of the bellows - referred to as annular. The tubing is normally made from sheet or coil that is rolled into a tube and longitudinally welded.
A flexible, thin-walled cylinder made up of corrugations one next to the other that can expand or contract under changing pressures.
light tight, folding sleeve which can be fitted between the lens and the film plane.
Large format cameras: The folding (piano accordion style) part that connects the standards (lens and film back). Also a camera accessory for smaller formats that aids close focusing. (see Monorail & Standard)
A circumferentially corrugated cylinder that is flexible and thin-walled and may have integral ends that axially contract or expand when under changing pressure.
A folding sleeve-like device that fits between the lens and the camera that allows for extended separation of lens and film plane. A bellows is used in close-up photography, and performs a function similar to that of extension tubes, except that the tubes are fixed and the bellows is minutely adjustable.
An accordion-like, light tight device. On a camera, it goes between the lens and the camera body. When used as an accessory to a 35mm camera, it enables it to focus on a close subject and achieve a greater-than life-size magnification on film. On an enlarger, it goes between the lens and the enlarger head and the lens is focused by adjusting the length of the bellows.
An accessory with flexible pleated material that goes between the camera and lens to extend the lens-to-film distance for close-up photography.
An accordion-like device that expands and contracts when internal pressure changes.
The folding (accordion) portion in some cameras that connects the lens to the camera body (like the Mamiya RZ). Also a camera accessory that, when inserted between lens and camera body, extends the lens-to-film distance for close focusing or macro phtography. Some retains the automatic functions where some have to stopdown the lens for manual exposure reading.
