WebA lenticular lens is an array of lenses, designed so that when viewed from slightly different angles, different parts of the image underneath are shown. [failed verification – see discussion] The most common example is the lenses used in lenticular printing, where the technology is used to give an illusion of depth, or to make images that appear to change …

WebCanon has sold zoom and prime L-series lenses for the discontinued FD lens mount, for the current EF lens mount used on all Canon EOS SLR cameras and for the RF mount used on full-frame ... incorporating dust and water-resistant rubber seals on some models.

WebFor a 35mm camera with a diagonal of 43mm, the most commonly used normal lens is 50mm, but focal lengths between about 40 and 58mm are also considered normal.The 50mm focal length was chosen by Oskar Barnack, the creator of the Leica camera.. Note that the angle of view also depends on the aspect ratio.For example, a "normal" lens on …

WebIn nature. The lens of the eye is the most obvious example of gradient-index optics in nature. In the human eye, the refractive index of the lens varies from approximately 1.406 in the central layers down to 1.386 in less dense layers of the lens. This allows the eye to image with good resolution and low aberration at both short and long distances. Another …

WebIn photography, distortion is particularly associated with zoom lenses, particularly large-range zooms, but may also be found in prime lenses, and depends on focal distance – for example, the Canon EF 50mm f /1.4 exhibits barrel distortion at extremely short focal distances. Barrel distortion may be found in wide-angle lenses, and is often seen at the …

WebDepth of focus is a lens optics concept that measures the tolerance of placement of the image plane (the film plane in a camera) in relation to the lens. In a camera, depth of focus indicates the tolerance of the film's displacement within the camera and is therefore sometimes referred to as "lens-to-film tolerance".

WebThe Canon EF-S lens mount is a derivative of the EF lens mount created for a subset of Canon digital single-lens reflex cameras with APS-C sized image sensors. It was released in 2003. Cameras with the EF-S mount are backward compatible with the EF lenses and, as such, have a flange focal distance of 44.0 mm. Such cameras, however, have more …

WebThe M42 lens mount is a screw thread mounting standard for attaching lenses to 35 mm cameras, primarily single-lens reflex models. It is more accurately known as the M42 × 1 mm standard, which means that it is a metric screw thread of 42 mm diameter and 1 mm thread pitch. (The M42 lens mount should not be confused with the T-mount, which …

WebThe Fujifilm X-mount is a type of interchangeable lens mount designed by Fujifilm for use in those cameras in their X-series line that have interchangeable-lenses.These lenses are designed for 23.6mm x 15.6mm APS-C sensors.. Various lens manufacturers use this mount, such as Fujifilm's own XF and XC lenses, Carl Zeiss AG (Touit lenses), Samyang …

WebThe EF 100 mm f /2.8 Macro USM lens is a prime lens made by Canon Inc. It is of the EF lens mount that fits the EOS camera system.There are three versions, the original, a second that adds a USM autofocus motor, and a recently released L series version that incorporates Image Stabilization (IS).. It is a macro lens, meaning that it is capable of reproducing an …
