Eastman Kodak has introduced a telephoto version of its compact dual-lens camera that offers Bluetooth. AnswerParty!
Eastman Kodak Company, commonly known as Kodak, is an American technology company focused on imaging solutions and services for businesses. The company is headquartered in Rochester, New York, United States and incorporated in New Jersey. It was founded by George Eastman in 1888.
Kodak provides packaging, functional printing, graphic communications and professional services for businesses around the world. Its main business segments are Digital Printing & Enterprise and Graphics, Entertainment & Commercial Films.
Digital photography uses an array of electronic photodetectors to capture the image focused by the lens, as opposed to an exposure on photographic film. The captured image is then digitized and stored as a computer file ready for digital processing, viewing, digital publishing or printing.
Until the advent of such technology, photographs were made by exposing light sensitive photographic film, and used chemical photographic processing to develop and stabilize the image. By contrast, digital photographs can be displayed, printed, stored, manipulated, transmitted, and archived using digital and computer techniques, without chemical processing.
A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
There is no major difference in principle between a lens used for a still camera, a video camera, a telescope, a microscope, or other apparatus, but the detailed design and construction are different. A lens may be permanently fixed to a camera, or it may be interchangeable with lenses of different focal lengths, apertures, and other properties.
In photography and cinematography, a telephoto lens is a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length. This is achieved by incorporating a special lens group known as a telephoto group that extends the light path to create a long-focus lens in a much shorter overall design. The angle of view and other effects of long-focus lenses are the same for telephoto lenses of the same specified focal length. Long-focal-length lenses are often informally referred to as telephoto lenses although this is technically incorrect: a telephoto lens specifically incorporates the telephoto group.
Telephoto lenses are sometimes broken into the further sub-types of medium telephoto: lenses covering between a 30° and 10° field of view (85mm to 135mm in 35mm film format), and super telephoto: lenses covering between 8° through less than 1° field of view (over 300mm in 35mm film format).
A rangefinder camera is a camera fitted with a rangefinder: a range-finding focusing mechanism allowing the photographer to measure the subject distance and take photographs that are in sharp focus. Most varieties of rangefinder show two images of the same subject, one of which moves when a calibrated wheel is turned; when the two images coincide and fuse into one, the distance can be read off the wheel. Older, non-coupled rangefinder cameras display the focusing distance and require the photographer to transfer the value to the lens focus ring; cameras without built-in rangefinders could have an external rangefinder fitted into the accessory shoe. Earlier cameras of this type had separate viewfinder and rangefinder windows; later the rangefinder was incorporated into the viewfinder. More modern designs have rangefinders coupled to the focusing mechanism, so that the lens is focused correctly when the rangefinder images fuse; compare with the focusing screen in non-autofocus SLRs.
Almost all digital cameras, and most later film cameras, measure distance using electroacoustic or electronic means and focus automatically (autofocus); however, it is not customary to speak of this functionality as a rangefinder.
The Kodak DC215 is a discontinued model of digital camera produced in Japan by the Eastman Kodak Company. This model does not have internal memory (only CompactFlash I cards), but a 4MB card is supplied with the camera. The camera has a 1 Megapixel sensor, a fixed focus lens with 2x optical zoom (F/4 wide, F/4.8 telephoto) and macro-setting and a built-in flash. The viewfinder is optical, it is possible to use the 1.8" rear LCD monitor as viewfinder ("Preview mode"), though Kodak does not recommend that due to high battery consumption. There was also a "Millennium Edition" which had a gold rather than silver case and came with some additional accessories.
The Kodak DC215 had a notorious problem with its battery compartment. This compartment, which takes in 4 AA batteries, is made of plastic and breaks easily. People usually resorted to makeshift solutions such as using rubber bands or duct tape to work around this common problem
