Tamron Lens Marking The Japanese company Tamron belongs to the second-tier manufacturers, releasing lenses for the most common systems. Like its competitors, Tamron has its own markings to indicate the most important qualities and characteristics of a lens. Di (Digitally integrated) is a generation of Tamron lenses optimized for use with full-frame DSLRs. They will work great with both film and cropped SLR cameras. Di II (Digitally integrated II) is a series of lenses designed for cameras with an APS-C matrix format (crop factor 1.5). Using such lenses on full frame cameras will result in severe vignetting in the image. Di III (Digitally integrated III) is the newest and smallest series of lenses for mirrorless cameras. AF (Autofocus) - in the old fashioned way, Tamron still indicates the abbreviation in the marking, indicating the presence of automatic focus. At the moment, all Tamron lenses have autofocus (only the type of motor differs). It is worth mentioning here the owners of Nikon cameras without a screwdriver drive, who are always interested in the question “Will autofocus work with my camera?”. Yes, all current Tamron lenses will work with the D40 / D40x / D60 / D3000 / D3100 / D3200 / D5000 / D5100 / D5200 except for the SP 200-500mm f/5-6.3 Di LD (IF), SP 180mm f/3.5 Di LD (IF) Macro 1:1 and 28-80mm f/3.5-5.6 Aspherical. By the way, earlier in the marking of lenses designed for Nikon cameras, the abbreviation BIM (Built-In Motor) was used. USD (Ultrasonic Silent Drive) - ultrasonic drive of the autofocus system of the lens. Such a drive is characterized by high focusing speed, low power consumption, and low noise level. PZD (Piezo Drive) - the same as USD, only in profile. IF (Internal Focusing) - lenses in which focusing occurs by moving only the internal lens groups. Because of this, IF lenses do not change their size when focusing, and their front element does not rotate, which makes it convenient to use gradient filters. Most Tamron lenses have this feature. VC (Vibration Compensation) is an optical lens stabilization system. Allows you to shoot at shutter speeds up to three stops slower than usual. The abbreviation VC is also indicated on the lens barrel near the mount. SP (Super Performance) is a series of lenses with improved optical and mechanical characteristics. Outwardly, they do not have any special differences. 60mm, 18-270mm is the focal length of a specific lens. In zoom lenses, the minimum focal length is listed first, followed by the maximum focal length. F2.0, F3.5-6.3 are the maximum possible aperture values for a particular lens. All zoom lenses specify two values: for the minimum and maximum focal lengths. In the simplified labeling of zoom lenses, the aperture value is not indicated. The following are abbreviations and abbreviations that indicate the optical properties of the lens, which Tamron often likes to boast of: XR (Extra Refractive Index) - an abbreviation for the use of glass lenses with a high refractive index. LD (Low Dispersion) - lenses with low dispersion. Used in most Tamron lenses to minimize chromatic aberration. XLD (eXtra Low Dispersion) - abbreviation indicates the use of lenses with extra low dispersion. AD (Anomal Dispersion) - indicates the presence in the optical design of lenses with anomalous dispersion. Aspherical or ASL - lenses have aspherical lenses in their design to combat spherical aberrations and distortion. Macro is Tamron's macro lens designation. It is indicated both on the lens body and in the marking. In addition to specialized macro lenses that shoot at 1:1 scale, there are also telephoto zoom lenses that, in the appropriate mode, allow you to shoot at a scale of 1:2, 1:3.5, 1:3.9, etc., as well as with a shorter focusing distance. ZL (Zoom Lock) - lock (lock) of the zoom ring. Some zoom lenses change their size when changing the focal length (zooming): the front of the lens moves forward (it is also called the “trunk”), and the lens becomes longer. To prevent the “trunk” from moving forward spontaneously (for example, when the camera hangs with the lens down), special blockers are used.
ASL Aspherical hybrid elements are used to reduce spherical aberration and distortion in the lenses.
A.S.P. The lens uses aspherical lenses.
DI, DIII DI - lenses designed to meet the requirements of digital cameras, can be used in film and full-format cameras. DI II - only for work with matrices of type (APS-C) and less.
HID The HID glass element minimizes chromatic aberration along the axis and at the corners of the frame. Chromatic aberration is known to be the biggest obstacle to high optical quality.
DG(defocus image control) - enlightenment of the rear lens to reduce reflections from the matrix. They differ from Sigma DC in that they can be installed on cameras with a full-format matrix and on film cameras.
IF(inner / internal focusing) - a lens with internal focusing of the optical unit, i.e. front lens does not rotate.
HSM(hyper sonic motor) is Sigma's term for a proprietary ultrasonic autofocus motor.
LD LD elements are made of special glass, which has an extremely low color scattering coefficient, which effectively combats chromatic aberration.
SHM Lightweight and extremely durable Tamron lens mount mechanism.
SP(Super Performance) - This line of lenses features improved performance and innovative design.

All topics in this section:
What is the diaphragm?
Aperture is usually understood as a changing round hole in the lens. The hole opens and closes with petals. The petals in this case are called aperture blades.
Exposure is the time from opening to closing the shutter doors, during which the light manages to get on the photosensitive element of the camera
Exposure is measured in seconds, minutes, hours, days. Usually, even a second is too long a shutter speed, therefore, shutter speed is almost always indicated in fractions of a second. For example, 1/60
Long exposure
Long exposure is usually used in low light conditions - indoors, at night or twilight. This shutter speed is more suitable for creative experiments - for example, at night
white balance
In short, it is simply called BB (white balance), in the English literature you can find WB (White balans), which does not change the essence. This is very important
Lenses
The lens is the most important part of the camera; it lets light into the device, transmitting information about the object being shot. A lot depends on the quality of the lens, first of all - clarity.
Nikon lens markings
D - D-series autofocus lenses transmit focus distance information to the camera. This allows the distance to the subject to be taken into account when calculating the exposure, which helps
Canon lens markings
AL Aspherical lenses. CA(Circular Aperture) - CaF2 circular aperture The lens uses Fluorite glass lenses.
Sigma lens markings
APO The lens design uses apochromatic lenses to correct chromatic aberration. ASP The lens uses aspherical lenses.
Tokina lens markings
ASTo eliminate spherical aberration, Tokina uses aspherical all-glass elements in many optical devices. Aspheric lens element surface right
Filters for lenses
The main purpose of a light filter is to change (absorb, polarize, refract) the light flux directed into the camera lens. In connection with this change in the luminous flux can
Canon lens designations
L- (Luxury) the lens belongs to Canon's line of professional lenses. Canon's high-end lenses using fluorite or special ED glass lenses, often dust- and water-resistant, are marked with a red ring
EF- designation of the mount (mounting the lens to the camera) of Canon EOS autofocus cameras.
EF-S- (short backfocus - short back working distance) - the designation of the bayonet mount for Canon EOS 300D, 350D, 400D, 20D, 20Da, 30D digital cameras with a non-full frame sensor. The Canon EF-S mount has a shorter working distance than the EF. Canon EF-S lenses have a protruding optical element and its mount at the back, which makes it impossible to mount EF-S lenses on cameras with an EF mount (film cameras, Canon 1Ds, 1Ds Mark II, 5D full-frame cameras). Attaching EF-S lenses to EF mount cameras may damage the camera or lens depending on the models!
USM- (Utlrasonic Motor) - an ultrasonic focus drive (motor) built into the lens and based on the conversion of ultrasonic vibrations of a piezoelectric element into mechanical energy. They have increased speed and focusing accuracy, they work almost silently. They have noticeably better performance in tracking autofocus (servo-AF) than conventional motors.
IS- (Image Stabilizer) - an optical image stabilization system built into the lens. Based on the shift of the corrective lens group inside the lens. It makes it possible to shoot handheld at shutter speeds 2-3 steps shorter without blurring pictures.
DO- (Diffractive Optical Elements) - the use of diffractive optical elements in the optical design of the lens. Allows you to reduce the weight and size of the lens, while maintaining outstanding optical performance. Differ in small size and weight, marked with a green ring.
TS-E- (Tilt-Shift) - special lenses with the possibility of perspective correction due to tilts and shifts of the optical unit.
FT-M. Full Time Manual - constant manual focus. The lens does not need to be switched to manual focus mode, because it is available all the time
I/R. Internal Focus Rear Focus - lenses with internal focusing or focusing of the rear lens group (with a non-rotating front lens)
The Canon EF series comes from film cameras, and although a digital camera sensor is smaller than a film frame, lenses can also be used with digital cameras. EF series lenses are compatible with all EOS series cameras.
The Canon EF-S series is relatively recent. The letter S (from the word Short - short) in the marking means "short rear working segment." The rear element of the lens is located closer to the image sensor. These lenses can be distinguished from EF lenses by the white mark on the lens mount (the EF has a red mark). In addition, the EF-S has a rear rubber ring to protect the lens from mounting on an incompatible camera, i.e. on a film camera, or a camera with a full-frame sensor (Canon EOS 5D, Canon EOS-1D series).
USM system.
Among the lenses of both series there are lenses equipped with the USM system. USM (UltraSonic Motor) is an ultrasonic ring motor that achieves fast and quiet focusing. In addition, these lenses are equipped with additional features that improve image quality, bringing it closer to the quality of professional L-series lenses.
Nikon lens designations
DX are short-rear, non-full-frame lenses designed specifically for use with Nikon digital cameras. Cannot be used with film cameras!
The designation of the lens may contain AF or AF-S(e.g. "Nikon AF Nikkor 50mm f/1.4D" or "Nikon AF-S Nikkor Micro 105mm f/2.8G IF-ED VR"). In the first case (AF), the lens is not equipped with its own autofocus motor, and a motor built into the camera (the so-called "screwdriver") is used to focus. In the second case (AF-S), the lens is equipped with its own autofocus motor (usually ultrasonic).
Please note that the new Nikon D40 does not support auto focus with AF lenses. Autofocus requires an AF-S or AF-I lens.
AF- Nikon autofocus lenses with a mechanical focus drive with a motor located in the camera.
AF-S- Nikon autofocus lenses with an ultrasonic focus drive built into the lens and based on the conversion of ultrasonic vibrations of a piezoelectric element into mechanical energy. They have increased speed and focusing accuracy, they work almost silently. They have noticeably better performance in tracking autofocus (servo-AF) than conventional motors.
D- the presence of a processor in the lens that transmits information about the focusing distance from the lens to the camera. It is necessary for the correct functioning of the modern i-TTL flash algorithm.
G- electronic control of the diaphragm. Improved aperture setting accuracy in 1/3-stop increments. There is no aperture ring on the lenses. Includes all D features.
VR- (Vibration Reduction) - an optical image stabilization system built into the lens. Based on the shift of the corrective lens group inside the lens. It makes it possible to shoot handheld at shutter speeds 2-3 steps shorter without blurring pictures.
IF- (Internal Focusing) - lens design, in which focusing occurs due to the movement of elements only inside the lens. Lenses with internal focusing do not change their size when focusing, they focus faster and are more convenient when using filters for which their position is important (polarizing, gradient, etc.).
DC- (Defocus Control) - special lenses with the ability to control the degree and nature of blurring the blur zone
PC- (Perspective Control) - special lenses with the ability to correct perspective due to tilts and shifts of the optical unit.
Micro- Special lenses for macro photography up to 1:1 scale.
Ai/Ai-s/Ai-D- Nikon non-autofocus lenses.
DX- Specially designed for digital SLR cameras.
The compact and lightweight DX Nikkor produces a smaller image and is specially designed and optimized for use with Nikon D2, D1, Nikon D100, D200, D80, D70s, D70, D50, D40 series digital SLR cameras. It is ideal when shooting landscapes with Nikon DSLRs, as well as when shooting scenes in tight spaces and for dramatizing perspective.
Note from aldus.ru: We do not recommend using the DX Nikkor lens with 35mm (135) or IX240 format cameras.
Optical glass type ED: An integral part of Nikkor telephoto lenses.
Nikon has developed ED type (Extra-low Dispersion) optical glass to be able to produce lenses with excellent sharpness and color correction achieved by minimizing chromatic aberration. Lenses with ED glass elements provide stunning sharpness and contrast even at maximum lens aperture.
SIC- Nikon's "Super-Integrated" Coating, delivers exceptional lens performance / Achieved by using a multi-layer lens coating that reduces ghosting and flare to negligible levels.
A.S.P.- aspherical lens elements. Aspherical lenses can almost completely solve the problem of coma and other types of aberration, even at the maximum value of the relative aperture of the lens. They are especially useful for eliminating distortion in wide-angle lenses. In addition, the use of aspherical lenses allows to reduce the weight and dimensions of the lens.
CRC- (Close-range Correction) Corrective focusing system for close objects, provides excellent image quality at close focusing distances and expands the focusing range.
The CRC system is used in fisheye lenses, wide angle lenses, the Micro series, and some Nikkor brand telephoto lenses.
RF- (Rear Focusing) "Rear" focusing: all optical elements of the lens are divided into several lens groups, and only the rear lens group moves to adjust the focus. This makes the auto focusing process smoother and faster.
SWM- silent wave motor; converts "traveling waves" into rotational energy to adjust focus. This makes it possible to realize a high-speed autofocus system featuring extremely high accuracy and ultra-low noise in operation.
M/A- advanced manual / automatic focus mode switching system; Allows you to switch from autofocus to manual focus almost instantly, even when AF tracking is in operation and regardless of the AF mode you are using.

Di The Di code stands for a new generation of lenses specifically adapted to the requirements of digital SLR cameras. As you know, digital SLR cameras impose more stringent requirements on lenses. The use of special technologies does not at all prevent the use of Di-marked lenses with film SLR cameras, and for digital SLR cameras, it is better to give preference to Tamron lenses marked Di or Di II (depending on the size of the sensor of your camera).
Di II Tamron's Di II designation refers to lenses designed exclusively for use in a reduced sensor digital SLR (sensor 24x16mm or smaller). The optical systems of these lenses are optimally adapted to the technical characteristics of digital SLR cameras.
Di II lenses take measures to prevent ghost images and reflections, for example, by applying special anti-reflective coatings to the surfaces of the optics. In addition, vignetting has been minimized to ensure uniform brightness in digital photography from the center to the corners of the frame. The zoom range of the Di II ZOOM lenses is ideally suited to the preferences of DSLR users.
SP Tamron's SP (Super Performance) series is a line of lenses designed to meet the highest design demands. The main priority of SP lenses are excellent technical parameters. In Tamron's product palette, SP lenses stand out for their impressive, innovative design.
XR In comparison with models of the past, it was possible to create an XR-Megazoom lens (models A03 and A06), which differs not only in a shortened overall length, but also in a reduced diameter, while maintaining the same optical power and aperture ratio. This outstanding achievement has been realized thanks to the use of lenses made of special glass with an increased refractive index (XRGlas). The result was lenses with very small image errors, but with reduced overall dimensions.
ASL To achieve optimum image quality and compactness, Tamron uses several aspherical hybrid elements in the Tamron 18-200mm, Tamron 28-200mm, Tamron 28-300mm and Tamron 24-135mm lenses. With the latest technology, Tamron's fast zoom lenses know nothing about spherical aberration and distortion.
The use of "hybrid aspherical" technology (for several optical elements of the lens) made it possible to obtain high image quality with minimal dimensions.
LD Chromatic aberration is a form of optical noise that reduces the sharpness of an image. LD elements are made of special glass, which has an extremely low color scattering coefficient (this parameter indicates the ability of glass to split a beam of light into components of the color spectrum).
As a result, effective compensation for chromatic aberration is provided, i.e. a problem that is especially relevant in telescopic lenses with a long focal length.
AD Anomalous scattering glass is a special variant of optical glass that has an abnormally large partial scattering ratio (the amount of scattering in a certain wavelength range within the visible light spectrum) relative to a specific wavelength. Combining AD glass elements with conventional optical glass with different scattering characteristics allows you to control the scattering coefficient of specific wavelengths.
This leads to effective compensation of axial chromatic aberration for telescopic lenses, as well as lateral chromatic aberration for traditional wide-angle lenses. AD elements are used in autofocus lenses of the Tamron AF 24-135mm and Tamron AF 28-300mm models.
HID The HID glass element minimizes chromatic aberration along the axis and at the corners of the frame. Chromatic aberration is known to be the biggest obstacle to high optical quality.
IF, ZL Tamron's internal focusing system improves optical performance by minimizing vignetting and suppressing focus-induced aberrations.
In addition, reducing the maximum distance from which focusing is possible allows you to perform macro photography in the Megazoom range (28-200 mm = 1:4; 28-300 mm = 1:2.9 and 24-135 mm = 1:3.3).
A useful feature that prevents the lens barrel from moving out during transportation is the original ZOOM lock mechanism developed by Tamron. This convenience is highly appreciated by experienced practical photographers as it eliminates the risk of inadvertent damage to the lens.
SHM Tamron's lightweight and extremely durable mechanism for mounting a lens on a camera. Significant weight savings and strength gains have been achieved by moving away from brass and switching to special high quality injection molded plastic reinforced with a stainless steel plate.
