Canon’s new EOS 7D has an 18-megapixel sensor (not full-frame), 8fps continuous shooting speed and 1920 x 1080 full HD video, plus a new 19-point autofocus system. The video mode has full manual control, and the camera has an external [...]
The level of random variation in the pixels of digital photos. The pixels (photosites) on sensors record the levels of light falling on them as an electrical signal. However, there’s always a certain level of random background electrical activity which [...]
Different types of digital camera use different sized sensors. Ignoring specialised studio cameras, the largest are in full-frame digital SLRs, the next largest are in APS-C format SLRs and Four Thirds cameras, while the smallest are in compact cameras.
The physical [...]
Digital SLR whose sensor is the same size as 35mm film. The majority of digital SLRs use a sensor that’s smaller than a 35mm film frame and closer to the size of an APS frame (which is why they’re sometimes [...]
