Polycarbonate is the material used whenever TAMRON produces high-precision components that require the strength to withstand rigorous use

To insure the highest levels of performance and durability without adding additional weight, For example, TAMRON all-in-one zoom lenses make extensive use of engineering plastic (polycarbonate) materials in many critical mechanical components of the lens. Indeed, polycarbonate of this caliber is the material of choice whenever we produce high-precision components that require the strength to withstand rigorous use.

A several-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening even when stopped down by two stops from the wide-open aperture

A several-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening even when stopped down by two stops from the wide-open aperture. This produces a smooth-edged bokeh in background highlights.

Leak-resistant seals throughout the lens barrel help protect your equipment when shooting outdoors

For greater protection when shooting outdoors, leak-resistant seals throughout the lens barrel help protect your equipment. ※The structure is moisture-resistant but does not completely prevent the ingress of water droplets.

Innovative coating technology that prevents ghosting and flare

Second-generation BBAR-G2 Coating is a groundbreaking advancement that provides vastly improved performance compared to the original BBAR (Broad-Band Anti-Reflection) Coating. The coating corrects for ghosting and flare to an unprecedented extent and renders fine subject detail with true clarity and stunning contrast even under backlit conditions.

A highly durable protective fluorine compound that is water- and oil-repellant

With the highly durable fluorine compound that has excellent water- and oil-repellent properties, the lens surface is much easier to wipe clean and less vulnerable to damaging effects of dirt, dust, moisture, and fingerprints, and enabling your important lenses to be continually protected on a long-time basis.

Zoom Lock switch prevents undesired extension of the lens barrel when carrying the camera/lens unit on a neck strap

Zoom Lock switch prevents undesired extension (creep) of the lens barrel when carrying the camera/lens unit on a neck strap. This enhances responsiveness in the field and helps protect the lens.

The characteristic of less of a tendency to separate a ray of light into a rainbow of colors effectively compensates for chromatic and lateral chromatic aberration

LD lens elements in help reduce chromatic aberrations. Chromatic aberration reduces the sharpness of an image, but glass with an extremely low dispersion index has less of a tendency to separate (diffract) a ray of light into a rainbow of colors. This characteristic allows the lens designer to effectively compensate for chromatic and lateral chromatic aberration which are a particular problem at wide-angle and telephoto focal lengths.

XLD lens elements made from specialized ultra-high-grade glass allow much greater control over chromatic aberration and magnification aberrations

XLD lens elements made from specialized ultra-high-grade glass allow much greater control over chromatic aberration and magnification aberrations than LD lens elements. XLD lens elements deliver the highest possible contrast, the finest detail, and superior imaging performance throughout the entire zoom range.

GM lens elements have a significant impact on minimizing distortion and enhancing the sharpness of the image at its periphery

GM lens elements are capable of efficiently correcting aberrations in the angle of view that changes significantly with an ultra wide-angle zoom lens. It has an especially significant impact on minimizing distortion and enhancing the sharpness of the image at its periphery. Furthermore, the molded-glass manufacturing method allows the fabrication of a wider range of lens shapes than the composite aspherical lens method.

TAMRON's unique VC mechanism effectively minimizes the effect of camera-shake and delivers a stable viewfinder image

TAMRON's unique VC mechanism uses a proprietary actuator and algorithms to deliver an extremely stable viewfinder image with excellent tracking by minimizing the effect of camera-shake, when shooting handheld under low-light conditions such as indoor or when shooting at night. It effectively reduces the degradation of picture quality.

The mechanism uses a three-coil system to electromagnetically drive the lens element that compensates for vibration, which glides smoothly on three balls with little friction. This simple mechanical structure is one of the secrets to TAMRON's compact lenses.

Also, the latest lenses applies AI technologies, that the lenses will choose the compensation characteristic for videography.

A linear motor focus mechanism for the highest levels of autofocus speed and precision

VXD is a linear motor focus mechanism that enables you to easily achieve focus from the MOD (Minimum Object Distance) to infinity, even at the fast-aperture, thanks to the speed and precision of this highly accurate autofocus system. Focus tracking is also extremely precise so you can capture sudden movements by your subject. The linear motor also suppresses drive noise and vibrations during focusing, making it ideal for shooting both still photos and video in environments that demand quietness.
