135 Film
135 film, more popularly referred to as 35 mm film or 35 mm, is a format of photographic film used for still photography. It is a film with a film gauge of loaded into a standardized type of magazine – also referred to as a cassette or cartridge – for use in 135 film cameras. The engineering standard for this film is controlled by ISO 1007 titled '135-size film and magazine'. The term 135 was introduced by Kodak in 1934 as a designation for 35 mm film specifically for still photography, perforated with Kodak Standard perforations. It quickly grew in popularity, surpassing 120 film by the late 1960s to become the most popular photographic film size. Despite competition from formats such as 828, 126, 110, and APS, it remains the most popular film size today. The size of the 135 film frame with its aspect ratio of 1:1.50 has been adopted by many high-end digital single-lens reflex and digital mirrorless cameras, commonly referred to as " full frame".

Focal Length
The focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power. A positive focal length indicates that a system converges light, while a negative focal length indicates that the system diverges light. A system with a shorter focal length bends the rays more sharply, bringing them to a focus in a shorter distance or diverging them more quickly. For the special case of a thin lens in air, a positive focal length is the distance over which initially collimated (parallel) rays are brought to a focus, or alternatively a negative focal length indicates how far in front of the lens a point source must be located to form a collimated beam. For more general optical systems, the focal length has no intuitive meaning; it is simply the inverse of the system's optical power. In most photography and all telescopy, where the subject is essentially infinitely far away, longer focal length (lower opti ...

Double-Gauss Lens
The double Gauss lens is a compound lens used mostly in camera lenses that reduces optical aberrations over a large focal plane. Design The double Gauss lens consists of two back-to-back Gauss lenses (a design with a positive meniscus lens on the object side and a negative meniscus lens on the image side) making two positive meniscus lenses on the outside with two negative meniscus lenses inside them. The symmetry of the system and the splitting of the optical power into many elements reduces the optical aberrations within the system. There are many variations of the design. Sometimes extra lens elements are added. The basic lens type is one of the most developed and used photographic lenses. The design forms the basis for many camera lenses in use today, especially the wide-aperture standard lenses used on 35 mm and other small-format cameras. It can offer good results up to with a wide field of view, and has sometimes been made at 1.0. Extra wide aperture f/1.4 Double Gau ...

Leica M
The Leica M mount is a camera lens mount introduced in 1954 with the Leica M3, and a range of lenses. It has been used on all the Leica M-series cameras and certain accessories (e.g. Visoflex reflex viewing attachment) up to the current film Leica M-A and digital Leica M11 cameras. This lens mount has also been used by Epson, Ricoh, Minolta, Konica, Cosina Voigtländer, Rollei, Carl Zeiss AG and Rollei Fototechnic on some of their cameras. Overview The Leica M mount was introduced in 1954 at that year's Photokina show, with the Leica M3 as its first camera. The 'M' stands for ''Messsucher'' or rangefinder in German. This new camera abandoned the M39 lens mount in favour of a new bayonet mount. The bayonet mount allowed lenses to be changed more quickly and made the fitting more secure. Other innovations introduced by the M3 included a single window for the viewfinder (for composition) and the rangefinder (for focussing). With a double-stroke film advance lever (later models hav ...

Pope John Paul II
Pope John Paul II ( la, Ioannes Paulus II; it, Giovanni Paolo II; pl, Jan Paweł II; born Karol Józef Wojtyła ; 18 May 19202 April 2005) was the head of the Catholic Church and sovereign of the Vatican City State from 1978 until his death in April 2005, and was later canonised as Pope Saint John Paul II. He was elected pope by the second papal conclave of 1978, which was called after John Paul I, who had been elected in August to succeed Pope Paul VI, died after 33 days. Cardinal Wojtyła was elected on the third day of the conclave and adopted the name of his predecessor in tribute to him. Born in Poland, John Paul II was the first non-Italian pope since Adrian VI in the 16th century and the second-longest-serving pope after Pius IX in modern history. John Paul II attempted to improve the Catholic Church's relations with Judaism, Islam, and the Eastern Orthodox Church. He maintained the church's previous positions on such matters as abortion, artificia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guide Number
When setting photoflash exposures, the guide number (GN) of photoflash devices (flashbulbs and electronic devices known as "studio strobes", "on-camera flashes", "electronic flashes", "flashes", and "speedlights")The Nikon brand name for its camera-mounted electronic flash products, ''Speedlight'', is frequently used in lowercase form (''speedlight'' ) as a generic term for hot shoe-mounted electronic flash devices while Canon uses the trade name ''Speedlite''. is a measure photographers can use to calculate either the required fstop for any given flash-to-subject distance, or the required distance for any given fstop. To solve for either of these two variables, one merely divides a device's guide number by the other. Though guide numbers are influenced by a variety of variables, their values are presented as the product of only two factors as follows: ::Guide number = f-number × distance This simple inverse relationship holds true because the brightness of a flash decl ...

Hot Shoe
Canon EOS 350D Hot shoe Proprietary hot shoe used by Minolta and older Sony cameras (Konica Minolta Maxxum 7D">Sony.html" ;"title="Minolta and older Sony">Minolta and older Sony cameras (Konica Minolta Maxxum 7D) A hot shoe is a mounting point on the top of a camera to attach a flash (photography), flash unit and other compatible accessories. It takes the form of an angled metal bracket surrounding a metal contact point which completes an electrical connection between camera and accessory for standard, brand-independent flash synchronization. The hot shoe is a development of the standardised "accessory shoe", with no flash contacts, formerly fitted to cameras to hold accessories such as a rangefinder, or flash connected by a cable. The dimensions of the hot shoe are defined by the International Organization for Standardization in ISO 518:2006. Details such as trigger voltage are not standardised; electrical incompatibilities are still possible between brands. Design The h ...

Flexible Printed Circuit
Flexible electronics, also known as ''flex circuits'', is a technology for assembling electronic circuits by mounting electronic devices on flexible plastic substrates, such as polyimide, PEEK or transparent conductive polyester film. Additionally, flex circuits can be screen printed silver circuits on polyester. Flexible electronic assemblies may be manufactured using identical components used for rigid printed circuit boards, allowing the board to conform to a desired shape, or to flex during its use. Manufacturing Flexible printed circuits (FPC) are made with a photolithographic technology. An alternative way of making flexible foil circuits or flexible flat cables (FFCs) is laminating very thin (0.07 mm) copper strips in between two layers of PET. These PET layers, typically 0.05 mm thick, are coated with an adhesive which is thermosetting, and will be activated during the lamination process. FPCs and FFCs have several advantages in many applications: * Tigh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
