Lens or camera fungus is the popular name for the infestation of optical devices such as lenses, low pass filter (OLPF) or the camera sensor, by fungal threads ().By germination of fungal spores and further spore formation, the infestation can spread beyond the initial fungal network.
The system consists of a very thin piece of filter glass placed in front of the image sensor; the area between the filter and the sensor is sealed, so no dust can enter. Whenever the camera is turned on, a piezoelectric driver induces a vibration in the filter glass, shaking dust off. A piece of adhesive located inside the camera traps removed ...
Such filters can be used both over color camera lenses, and to filter visible light from IR illumination sources. Such filter stock is most easily made available most simply by having any commercial color negative film developed after being fully exposed to light. The leaders of 35mm film are ideal for this, without wasting an entire roll of film.
The first digital camera to use a Foveon X3 sensor was the Sigma SD9, a digital SLR launched in 2002. [5] It used a 20.7 × 13.8 mm, 2268 x 1512 × 3 (3.54 × 3 MP) iteration of the sensor and was built on a Sigma-designed body using the Sigma SA mount.
The EOS M50, a crop-sensor (APS-C) mirrorless camera in Canon M series lineup introduced in February 2018. It is the first camera with DIGIC 8 processor. The EOS R, the first full-frame mirrorless camera from Canon, introduced in October 2018. The Canon PowerShot SX740 HS and SX70 HS cameras, introduced in 2018. The EOS RP, introduced in ...
Fujifilm FinePix X100. This is a list of large sensor fixed-lens cameras, also known as premium compact cameras or high-end point-and-shoot cameras.These are digital cameras with a non-interchangeable lens and a 1.0‑type (“1‑inch”) image sensor or larger, excluding smartphones and camcorders.
Modern ignition interlock devices use an alcohol-specific fuel cell for a sensor. A fuel cell sensor is an electrochemical device in which alcohol undergoes a chemical oxidation reaction at a catalytic electrode surface to generate an electric current. This current is then measured and converted to an alcohol equivalent reading.
To help extend the exposure range, some smaller sensor cameras will also incorporate an ND filter pack into the aperture mechanism. [46] The apertures that smaller sensor cameras have available give much more depth of field than equivalent angles of view on a DSLR. For example, a 6 mm lens on a 2/3″ sensor digicam has a field of view similar ...
