aberration: A factor that adversely affects imaging in an optical system. The design of any optical system is dedicated to correcting various aberrations with different methods, such as: spherical aberration and chromatic aberration, vignetting, coma and distortion. agc automatic gain control: This is a built-in function used to automatically adjust the gain level.
A minimalist pendant lamp is a simple and sleek lighting fixture that focuses on clean lines and minimal decoration. It typically consists of a single pendant that hangs from the ceiling and provides direct lighting to a specific area. The design is often characterized by a minimalistic shape, such as a cylindrical or spherical shade, and is usually made from materials like metal, glass, or plastic. The lamp may also feature a minimalist color palette, such as black, white, or metallic tones, to further enhance its minimalist aesthetic. Overall, a minimalist pendant lamp is a stylish and understated lighting solution that can complement a variety of interior design styles.
A minimalist chandelier is a simple and sleek lighting fixture that features clean lines and a minimalist design aesthetic. It typically has a minimal number of elements and a streamlined shape, often made from materials such as metal or glass. The focus is on simplicity and functionality, with a design that is understated yet elegant. A minimalist chandelier can add a touch of modern sophistication to any space while still maintaining a minimalist and uncluttered look.

alc control Automatic light compensation: An automatic aperture setting, so that bright subjects will not affect the overall exposure. Adjusting to the peak (weakening) direction will increase the sensitivity; when set to averade (average) the sensitivity will decrease. Average is the general factory setting.
angle of view: The diagonal angle of the field of view taken by the camera lens is called the angle of view. Usually wide-angle lens has a larger angle of view;
The telephoto lens has a narrower angle of view.
Aperture: Originally means the opening of the lens. Generally refers to a device that controls the opening of the lens to control the amount of light passing through the lens. The size of the aperture can be fixed or variable. The size of the aperture also determines the depth of field. The use of a smaller aperture (such as f / 11 f / 16) tends to have a larger depth of field.
aspect ratio: refers to the aspect ratio of the shooting screen, the general 135 camera is 24x36mm, and the aspect ratio is 2: 3
aspherical lens: An optical element containing an aspherical surface. At present, there are a variety of methods for manufacturing aspheric lenses, such as: die casting molding, injection casting, composite molding, etc. These processes rely on high-precision manufacturing technology. Tamron has successfully developed a compound aspheric lens-a high-precision mold manufacturing and lens coating technology.
back focus (back focal distant): The distance from the second principal point of the optical element to the focal plane.
Barrel: A barrel-shaped structure in which lenses and other components are installed.
bbar multi-coating: Tamron's unique bbar multilayer coating. bbar is broad-band anti-reflective, which means wide frequency anti-reflection. Tamron has a technology of coating a very thin anti-reflection layer on the surface of the lens, which can greatly improve the sharpness and color reproduction ability of the lens.
depth of field: The clear area in front of and behind the focused subject.
field of view: The largest area captured through the lens.
finder: The viewfinder on the camera. Through it, the photographer can easily compose the picture.
fixed focal length: This lens has only a single focal length.
fixed focus (pan focus) fixed object distance: the shooting object distance of this lens is fixed, and does not provide focus adjustment capability.
flank back (flange back focal distance): The distance from the lens mounting plane to the focal plane.
f-number (f / #): f value, indicating the aperture size.
focal length: focal length of the lens
lens shade: lens hood
low dispersion (ld) hybrid aspheric element: low dispersion lens, this is a special optical material, referred to as ld. The role of the ld lens is to overcome the inherent dispersion of the lens.
minimun object distance: shortest focusing distance, abbreviated as: mod
Off-the-film-metering focal plane metering: This is an advanced metering method on the camera. The metering element reads light data directly from the focal plane.
quad cam zoom: 4 cam zoom mechanism. This is the zoom mechanism first adopted by Tamron on its af28-300 lens.
vignetting: The black corner phenomenon at the 4 corners of the screen.
wide angle lens: wide angle lens.
zoom lens: zoom lens
zoom rati Zoom magnification.
