Cross section of SLR camera. Until the development of SLR, all cameras with viewfinders had two optical light paths: one through the lens to the film, and another positioned above (TLR or twin-lens reflex) or to the side (rangefinder). Because the viewfinder and the film lens cannot share the same optical path, the viewing lens is aimed to ...
A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that combines the optics and mechanisms of a single-lens reflex camera with a solid-state image sensor and digitally records the images from the sensor. The reflex design scheme is the primary difference between a DSLR and other digital cameras.
These cameras use the Sigma SA-mount, for which Sigma makes a line of lenses. The Sigma DSLR cameras that use the SA mount are the Sigma SD9, SD10, SD14, SD15 and SD1 Merrill. These cameras are noteworthy for their use of the Foveon X3 sensor, an image sensor that works on quite different principles from the sensors used in all other digital ...
Normal operation in an SLR camera involves flipping the mirror up out of the light-path just before the shutter opens, and then returning it when the shutter closes (although very early SLR's required the shutter to be cocked for the mirror to return). This causes vibration of the camera, particularly when the mirror slaps into the top of the ...
A "top camera" which will be used to take the photograph. Typically this is a digital SLR or digital compact camera with a macro lens or macro function. A "contraption" to link the two cameras and block out any excess light. The contraption may be a simple cardboard tube, or an open ended box that fits around the bottom camera.
These Pentax 6 × 7 series cameras resembled huge 35mm SLR camera in look and function. In 2010 Pentax introduced a digital version of the 645, the 645D, with a Kodak-built 44X33 sensor. Pentax Medium Format 6×7 SLR from the 1980s. Used 120/220 roll film and featured an electronically timed focal plane shutter and interchangeable lenses and ...
This is the extent of self-timer release available. All functions are activated by the left-hand front located threaded shutter release button. A film-cutting device is located inside the camera. It enables a partially exposed film to be removed from the camera in daylight for processing provided the left-hand take-up spool was placed in a ...
Basically a stripped down Minolta SR-2 with shutter speeds reduced to 1/500 of a second rather than the SR-2's 1/1000 of a second. Next came the Minolta SR-3. The camera had an ability to mount a selenium meter, which was then linked to the shutter speed. This particular camera was released in 1960, two years before the release of the SR-7.
