In mathematics, a fusion frame of a vector space is a natural extension of a frame.It is an additive construct of several, potentially "overlapping" frames. The motivation for this concept comes from the event that a signal can not be acquired by a single sensor alone (a constraint found by limitations of hardware or data throughput), rather the partial components of the signal must be ...
The sequence of lens designations may differ in literature. See also full list of Nikon designations, Sigma designations, Tamron designations and Tokina designations.. Nikon AF-S/Sigma HSM/Tamron USD or PZD: The lens contains an integrated ultrasonic focus motor based on piezoelectricity, which enables quiet or low noise autofocus operation.
Standard codes are followed when designing (or manufacturing) a piping system. Organizations which promulgate piping standards include: ASME: American Society of Mechanical Engineers
The Megadap MTZ11 contains a focusing helicoid with 6.5 mm of extension which is used for autofocus. This range is sufficient to cover the full focusing range of lenses up to around 50 mm focal length. [119] The Techart TZM-01 is similar to the Megadap MTZ11 and enables autofocus with M-mount lenses. [120]
35 mm equivalent focal lengths are calculated by multiplying the actual focal length of the lens by the crop factor of the sensor. Typical crop factors are 1.26× – 1.29× for Canon (1.35× for Sigma "H") APS-H format, 1.5× for Nikon APS-C ("DX") format (also used by Sony, Pentax, Fuji, Samsung and others), 1.6× for Canon APS-C format, 2× for Micro Four Thirds format, 2.7× for 1-inch ...
