Characterized by classic appearance and high optical performance. A technology used for reducing or even eliminating the effects of camera shake. Gyro sensors inside the lens detect camera shake and pass the data to a microcomputer.
Then an image stabilization group of elements controlled by the microcomputer moves inside the lens and compensates camera shake in order to keep the image static on the imaging sensor or film. Lens name as indicated on the lens barrel usually on the front ring. With lenses from film era, may vary slightly from batch to batch. It has an aspect ratio of , and a diagonal measurement of approximately 43mm.
The name originates with the total width of the film which was the primary medium of the format prior to the invention of the full frame digital SLR. Historically the 35mm format was sometimes called small format to distinguish it from the medium and large formats. APS-C is an image sensor format approximately equivalent in size to the film negatives of Medium format is a film format or image sensor format larger than 36x24mm 35mm but smaller than 4x5in large format.
Angle of view describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view. As the focal length changes, the angle of view also changes. The shorter the focal length eg 18mm , the wider the angle of view.
Conversely, the longer the focal length eg 55mm , the smaller the angle of view. A camera's angle of view depends not only on the lens, but also on the sensor. Imaging sensors are sometimes smaller than 35mm film frame, and this causes the lens to have a narrower angle of view than with 35mm film, by a certain factor for each sensor called the crop factor.
This website does not use the angles of view provided by lens manufacturers, but calculates them automatically by the following formula: A lens mount is an interface — mechanical and often also electrical — between a camera body and a lens. A lens mount may be a screw-threaded type, a bayonet-type, or a breech-lock type. Modern camera lens mounts are of the bayonet type, because the bayonet mechanism precisely aligns mechanical and electrical features between lens and body, unlike screw-threaded mounts.
Lens mounts of competing manufacturers Canon, Nikon, Pentax, Sony etc. In addition to the mechanical and electrical interface variations, the flange focal distance from the lens mount to the film or sensor can also be different.
Lens construction — a specific arrangement of elements and groups that make up the optical design, including type and size of elements, type of used materials etc. Element - an individual piece of glass which makes up one component of a photographic lens.
Photographic lenses are nearly always built up of multiple such elements. Group — a cemented together pieces of glass which form a single unit or an individual piece of glass. The advantage is that there is no glass-air surfaces between cemented together pieces of glass, which reduces reflections. The flange focal distance FFD , sometimes called the "flange back", is the distance from the mechanical rear end surface of the lens mount to the focal plane.
The focal length is the factor that determines the size of the image reproduced on the focal plane, picture angle which covers the area of the subject to be photographed, depth of field, etc. The largest opening or stop at which a lens can be used is referred to as the speed of the lens.
The larger the maximum aperture is, the faster the lens is considered to be. Lenses that offer a large maximum aperture are commonly referred to as fast lenses, and lenses with smaller maximum aperture are regarded as slow.
In low-light situations, having a wider maximum aperture means that you can shoot at a faster shutter speed or work at a lower ISO, or both. The minimum distance from the focal plane film or sensor to the subject where the lens is still able to focus. Determines how large the subject will appear in the final image. For example, a magnification ratio of means that the image of the subject formed on the film or sensor will be the same size as the subject in real life.
For this reason, a ratio is often called "life-size". Provides highly accurate diaphragm control and stable auto exposure performance during continuous shooting. The lens has two rings, one is for pre-setting, while the other is for normal diaphragm adjustment. The first ring must be set at the desired aperture, the second ring then should be fully opened for focusing, and turned back for stop down to the pre-set value.
The lens features spring mechanism in the diaphragm, triggered by the shutter release, which stops down the diaphragm to the pre-set value. The spring needs to be reset manually after each exposure to re-open diaphragm to its maximum value. The camera automatically closes the diaphragm down during the shutter operation.
On completion of the exposure, the diaphragm re-opens to its maximum value. As a general rule, the more blades that are used to create the aperture opening in the lens, the rounder the out-of-focus highlights will be. Some lenses are designed with curved diaphragm blades, so the roundness of the aperture comes not from the number of blades, but from their shape. However, the fewer blades the diaphragm has, the more difficult it is to form a circle, regardless of rounded edges.

Lenses that accept front mounted filters typically do not have gaskets behind the filter mount. It is recommended to use a filter for complete weather resistance when desired. Helps keep lenses clean by reducing the possibility of dust and dirt adhering to the lens and by facilitating cleaning should the need arise.
