Camera lens properties i Camera lens properties A camera lens (also known as photographic lens, objective lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically. While in principle a simple convex lens will suffice, in practice a compound lens made up of a number of optical lens elements is required to correct (as much as possible) the many optical aberrations that arise. Some aberrations will be present in any lens system. It is the job of the lens designer to balance these out and produce a design that is suitable for photographic use and possibly mass production. A lens may be permanently fixed to a camera, or it may be interchangeable with lenses of different focal lengths, apertures, and other properties. More information...
Lens type i Lens type Bei Fotoobjektiven unterscheidet man weiter nach dem Bildwinkel, der bei gegebenem Bildformat die Brennweite bestimmt. More information...	Telephoto lens i Telephoto lens In photography and cinematography, a telephoto lens is a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length. This is achieved by incorporating a special lens group known as a telephoto group that extends the light path to create a long-focus lens in a much shorter overall design. The angle of view and other effects of long-focus lenses are the same for telephoto lenses of the same specified focal length. Long-focal-length lenses are often informally referred to as telephoto lenses although this is technically incorrect: a telephoto lens specifically incorporates the telephoto group. More information... , Wide angle lens i Wide angle lens In photography and cinematography, a wide-angle lens refers to a lens whose focal length is substantially smaller than the focal length of a normal lens for a given film plane. This type of lens allows more of the scene to be included in the photograph, which is useful in architectural, interior and landscape photography where the photographer may not be able to move farther from the scene to photograph it. More information...
Lens mount i Lens mount A lens mount is an interface — mechanical and often also electrical — between a photographic camera body and a lens. It is confined to cameras where the body allows interchangeable lenses, most usually the single lens reflex type or any movie camera of 16 mm or higher gauge. Lens mounts are also used to connect optical components in instrumentation that may not involve a camera, such as the modular components used in optical laboratory prototyping which join via C-mount or T-mount elements.

Focal length i Focal length The focal length of an optical system is a measure of how strongly it converges (focuses) or diverges (diffuses) light. A system with a shorter focal length has greater optical power than one with a long focal length. More information...	28 - 105 mm
Focal Length APS-C / DX (35mm film equivalent) i Focal Length APS-C / DX (35mm film equivalent) In photography, the 35 mm equivalent focal length is a measure that indicates the angle of view of a particular combination of a camera lens and film or sensor size. The term is useful because most photographers experienced with interchangeable lenses are most familiar with the 35 mm film format. More information...	43 - 161 mm
Sensor compatibility	Vollformat
Number of diaphragm blades	9 x
Filter thread i Filter thread Als Filtergewinde bezeichnet man ein Anschlussgewinde von Foto- und Video-Objektiven zur Aufnahme von optischen Filtern. Dieses Gewinde befindet sich meist an der Vorderseites kurz vor der Frontlinse. Für die Aufnahme von Streulichtblenden haben die meisten Objektive einen separaten Anschluss. More information...	62 mm
Number of lenses i Number of lenses A lens is an optical device which transmits and refracts light, converging or diverging the beam. More information...	15
Number of lens groups i Number of lens groups Gibt an, in wie viele Gruppen die Linsen aufgeteilt sind.	11
Zoom function i Zoom function The device has a zoom function.	Yes
Optical zoom i Optical zoom A zoom lens is a mechanical assembly of lens elements with the ability to vary its focal length (and thus angle of view), as opposed to a fixed focal length (FFL) lens. More information...	3.70 x

Focusing i Focusing In geometrical optics, a focus, also called an image point, is the point where light rays originating from a point on the object converge. Although the focus is conceptually a point, physically the focus has a spatial extent, called the blur circle. This non-ideal focusing may be caused by aberrations of the imaging optics. In the absence of significant aberrations, the smallest possible blur circle is the Airy disc, which is caused by diffraction from the optical system's aperture. Aberrations tend to get worse as the aperture diameter increases, while the Airy circle is smallest for large apertures. More information...
Autofocus i Autofocus Autofocus (or AF) is a feature of some optical systems that allows them to obtain (and in some systems to also continuously maintain) correct focus on a subject, instead of requiring the operator to adjust focus manually. More information...	Yes
Manual focus i Manual focus Es besteht die Möglichkeit manuell zu fokussieren. Der Autofokus wird somit nicht verwendet.	Yes
Minimum focus distance i Minimum focus distance Die kürzeste Distanz welche unterstützt wird.	50 cm
