Olympus and OM-SYSTEM cameras are almost all Micro Four Thirds mirrorless cameras (there’s one exception – the waterproof Tough TG-6 uses a smaller 1/2.3-inch sensor and has a fixed zoom lens). Micro Four Thirds is a sensor standard and lens mount; the sensor itself measures 17.3mm x...
in doing so the effective focal distance changes. For example, a Canon APS-C format DSLR has a magnification factor, also known as a “crop factor,” of 1.6. Meaning that when used with a 50mm lens, it will capture an image that...

Canon has officially announced the RF 75-300mm F/4-5.6, a new entry-level telephoto zoom lens designed for its EOS R mirrorless system. This new RF-mount lens serves as the spiritual successor to the widely used EF 75-300mm F/4-5.6 III, which debuted in 1999. Targeted at beginner ph...

Folded Tele cameras comprising an optical path folding element (OPFE) for folding a first optical path OP1 to a second optical path OP2, a lens including N=8 lens elements, the lens being divided into three lens groups numbered, in order from an object side of the lens, G1, G2 and ...
The lens has focus, zoom, and aperture rings; the latter can be “de-clicked” for video shooting. There’s also a focus hold button, whose function can be customized. The lens is dust and moisture-resistant (but not 100%, Sony points out), and the front element has a fluorine coatin...

The matrix of intrinsic parameters does not depend on the scene viewed, and once estimated, the matrix can be re-used (as long as the focal length is fixed (in the case of zoom lens)). The joint rotation-translation matrix [R|t] is called a matrix of extrinsic parameters. It is ...
