When using non-auto aperture lenses, a press of the AE-L button with the camera in manual mode will meter the scene and set the shutter speed. Some non-Pentax K-mount lenses have been reported not to mount on the camera, [citation needed] because a plate protecting the aperture stop-down lever is slightly deeper. [citation needed]
There are many techniques and pieces of commercially manufactured equipment for attaching digital single-lens reflex (DSLR) cameras and even basic point and shoot cameras to telescopes. Consumer-level digital cameras suffer from image noise over long exposures, so there are many techniques for cooling the camera, including cryogenic cooling ...

Full-spectrum photography is a subset of multispectral imaging, defined among photography enthusiasts as imaging with consumer cameras the full, broad spectrum of a film or camera sensor bandwidth. In practice, specialized broadband/full-spectrum film captures visible and near infrared light, commonly referred to as the " VNIR ".
All current film and digital SLR cameras produced by Canon today use the EOS autofocus system. Canon introduced this system in 1987 along with the EF lens mount standard. The last non-EOS based SLR camera produced by Canon, the Canon T90 of 1986, is widely regarded as the template for the EOS line of camera bodies, although the T90 employed the ...
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 ...
