English (EN) A lens with a non-spherical curve used to compensate for a variety of aberrations, including spherical aberrations. Such lenses are effective in controlling the distortion prevalent in wide-angle ...
A system that uses multiple independently-moving lens groups to ensure that the image plane remains flat even at close distances.
A short form of “subject-to-camera distance information”, for use only where space restrictions prohibit use of the full term. Subject-to-camera distance information refers to the data supplied to ...
The image sensing area is reduced and images stored in a memory buffer, where a series of images is compared to calculate the amount of movement produced by the vibration and the image sensing area ...
Used in reference to objects that show little change in their refractive index at different wavelengths. Extra-low dispersion lenses are used in making ED (extra-low dispersion) lens systems with ...
A measure of the change in the angle of a lightwave or other wave traveling in a straight line when it passes across the boundary between two different mediums. “HRI” is an abbreviation of “high ...
system in which only the internal lens group shifts during focusing. IF benefits include focusing without changing the physical length of a lens body, faster focusing, reduced diameter of the ...
