Image-stabilized binoculars are binoculars that have a mechanism for decreasing the apparent motion of the view due to binocular movement. [1] Such binoculars are designed to minimize image shaking in hand-held applications. Higher-power binoculars magnify the image more, but the image shift is also increased. This means that even minor hand ...
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation about the optical axis (). [1]
Some binoculars use image-stabilization technology to reduce shake at higher magnifications. This is done by having a gyroscope move part of the instrument, or by powered mechanisms driven by gyroscopic or inertial detectors, or via a mount designed to oppose and damp the effect of shaking movements.
Images can be stabilized mechanically with optics mounted on the eye itself, or the image can be continually updated on a display to counteract the effects of eye movements. [5] Because no existing method creates perfect image stabilization, this leaves open the question of whether all perfectly stabilized images disappear completely. [6]
The Canon EF 75–300mm f / 4–5.6 III lens. Introduced in 1991, the Canon EF 75–300mm f / 4–5.6 lens is a telephoto zoom lens for Canon EOS single-lens reflex cameras with an EF lens mount. There are 3 basic types of the lens: the IS USM (Image Stabilization, Ultra Sonic Motor), the USM (USM, no IS) and non-USM (no USM, no IS).
The consumer version is also image-stabilized, but replaces the USM motor drive with STM, has a variable maximum aperture, and also lacks a macro feature. Canon EF 70–200mm lens has both image-stabilized and non-IS versions with maximum apertures of f/2.8 and f/4.0, and continues the 24–70mm's maximum focal length through 200mm
Canon in 2009 created the first lens with Hybrid IS (Image Stabilization) which compensates both angle camera shake and shift camera shake with the Canon EF 100mm f/2.8L Macro IS USM. Canon in 2010 was the first to create a lens with Fluoride coating. That lens was the Canon EF 70-300mm f/4-5.6L IS USM.
Introduced on 15 September 2016, Canon EF 70-300mm f / 4-5.6 IS II USM lens is the second Canon lens equipped with Nano USM technology, a focusing motor that combines the benefits of a ring USM (ultrasonic motor) for high-speed AF during still photo shooting and lead-screw type STM (stepping motor) for smooth and quiet video autofocusing (AF).
