Product Description

True to its high-end G Lens heritage, the SELP18105G lens features two ED glass elements and three aspherical elements for high resolution and contrast throughout the entire zoom range.

From the Manufacturer

E PZ 18-105mm F4 G OSS Power Zoom Lens

The first Sony G Lens created specifically for E-mount cameras is true to its heritage, achieving outstanding resolution and contrast throughout the zoom range thanks to an advanced optical design incorporating two ED glass elements and three aspherical elements. From wide angle to medium telephoto, this power zoom lens covers approximately a 6x zoom range with a constant F4 aperture.

Technology

Circular Aperture

When changing your aperture to defocus the background, the light sources appear blurred. This ‘bokeh’ effect of the blurred background can be enhanced with circular aperture blades used in this lens. Conventional aperture blades have flat sides creating unappealing polygonal shaped defocussed points of light. α lenses overcome this problem through a unique design that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed by 2 stops. Smoother, more natural defocusing can be obtained as a result.

ED (Extra-low Dispersion) glass

As focal lengths get longer, lenses built with conventional optical glass have difficulties with chromatic aberration, and as a result images suffer from lower contrast, lower color quality, and lower resolution. ED glass dramatically reduces chromatic aberration at telephoto ranges, and provides superior contrast across the entire image, even at large aperture settings. Super ED glass provides enhanced compensation for chromatic aberration.

Aspherical lens elements

Aspherical lens design dramatically reduces spherical aberration while also reducing lens size and weight. Spherical aberration is a slight misalignment of the light rays projected on the image plane. This is caused by differences in refraction at different points on conventional spherical lenses which degrade image quality in large-aperture lenses. Specially shaped “aspherical” elements near the diaphragm restore alignment of light rays at the image plane, maintaining high sharpness and contrast even at maximum aperture and can also be used at other points in the optical path to reduce distortion. Well-designed aspherical elements can reduce the total number of elements required in the lens, thus reducing overall size and weight. Advanced Aspherical (AA) elements are an evolved variant, featuring an extremely high thickness ratio between the center and periphery. AA elements are exceedingly difficult to produce, relying on the most advanced molding technology to consistently and precisely achieve the required shape and surface accuracy, resulting in significantly improved image accuracy and quality.

Lens-based optical image stabilization

Gyro sensors built into the lens detect even the slightest movement, and the stabilization lens is precisely shifted to counteract any image blur that might occur. The use of precision, quiet linear motors and technology inherited from high-end Sony professional camcorders results in exceptionally quiet, effective image stabilization that contributes to high-quality movies as well as stills.

Additional Features

Internal focusing

Only the middle groups of the optical system move to achieve focus, so the overall length of the lens does not change. Other important benefits include fast autofocusing and a short minimum focusing distance. Also, the filter thread at the front of the lens does not rotate, which is convenient if you’re using a polarizing filter.

AA elements are exceedingly difficult to produce, relying on the most advanced molding technology to consistently and precisely achieve the required shape and surface accuracy, resulting in significantly improved image accuracy and quality.

Distance encoder

The distance encoder plays an integral part in ADI flash metering, which delivers high precision flash metering that is unaffected by the reflectance of subjects or backgrounds. The distance encoder is a lens component that directly detects the position of the focusing mechanism, and sends a signal to the CPU in order to measure distance to the subject. During flash photography, this data is very useful in calculating how much flash output is appropriate to the scene.

Lens-based optical image stabilization

Gyro sensors built into the lens detect even the slightest movement, and the stabilization lens is precisely shifted to counteract any image blur that might occur. The use of precision, quiet linear motors and technology inherited from high-end Sony professional camcorders results in exceptionally quiet, effective image stabilization that contributes to high-quality movies as well as stills.

Super Performance (SP) for Discriminating Shooters
Tamron SP (Super Performance) series is a line of ultra-high-performance lenses designed and manufactured to the exacting specifications demanded by professionals and others who require the highest possible image quality. In creating SP lenses Tamron’s optical designers put their foremost priority on achieving superior performance parameters – they are all designed to a higher standard with little regard for cost constraints. As a result, Tamron lenses bearing the SP designation feature impressive and innovative designs that have established an enviable reputation for excellence among those knowledgeable photographers that demand the very best.

A Full-Time Manual Focus Makes Fine Tuning Easy
All Tamron lenses have high auto focus precision and are designed to capture subjects easily and in almost any situation, yet sometimes a photographer wants to fine-tune and make adjustments on the fly. The integration of a full-time manual focus offers just that: instead of fumbling with switches, photographers can from auto-focus to manual-focus by simply adjusting the focus ring. This feature helps the lens produce impressive results even in telephoto situations where the depth of field is narrow.

Cleaner Crisper Images without Flare or Ghosting
The new BBAR (Broad-Band Anti-Reflection) reduce the lens reflection and dispersion that cause ghosting and flare. The coating enhances light transmission in both the short and long wavelength ranges, ensuring excellent performance in all photographic conditions. Additionally, internal surface coatings are applied to cemented surfaces of all lens elements to deliver sharp, high-contrast images and flawless color re-production.

Vibration Compensation (VC) Mechanism-Making Telephoto & Low Light a New Medium
The actuator and algorithms, developed in-house at Tamron, provide the power that gives VC (Vibration Compensation) it’s excellent tracking performance and smooth, stable viewfinder image. Tamron’s VC mechanism provides a three-coil system, whereby the three driving coils activate the shake-compensating VC lens groups electromagnetically via three steel balls. The VC lens elements are held in place only by contact with the steel balls, achieving smooth movement with little friction, helping to eliminate the blur from camera shakes for clean shots night or indoors, or in macro and telephoto situations, hand held has never been this easy.

Speed is Nothing if not Stable
Fast and accurate without so much as a whisper. The SP 70-300mm F4-5.6 Di VC USD is the first to boast Tamron’s new Ultra Silent Drive (USD). USD is Tamron’s latest autofocus motor technology rotor, converting, converting ultrasonic waves into torque to quietly deliver a new level of focus precision and speed. Because it’s still built on a rotor it’s full time manual focus is as easy as ever-allowing the photographer smooth manual focusing without having to fumble with a switch. With advanced motor technology and newly developed software, Tamron’s USD delivers a practical, precise, noiseless photographic experience at turbo speed. For those dynamic sports shots, moving vehicles, or fast moving subjects, there has never been a better option.

Extra Low Dispersion (XLD) Lens
Extra Low Dispersion (XLD) lens elements made from specialized ultra-high-grade glass allow Tamron lens designers to achieve much greater control over chromatic aberration (color fringing) and magnification aberrations, the two major factors that inhibit image quality enhancement. In combination with LD elements, XLD elements are used to achieve sophisticated lenses that deliver the highest possible contrast, the finest detail, and superior imaging performance throughout the entire zoom range.

Full Frame Sensor for Ulitmate Versatility
The SP 70-300mm F/4-5.6 DI VC USD is one of Tamron’s Digitally Integrated (Di) designs. The Di series is the mark of Tamron lenses that are format-versatile since they can be used on Digital APS-C, full-frame and 35mm SLR cameras.

Auto-focus/Manual-focus (AF/MF) Switch Mechanism on the Focus Ring
The ability to switch quickly between auto-focus (AF) and manual-focus (MF) is a great asset in many types of shooting, especially sports and nature photography. This is easily accomplished with Tamron’s ingenious AF/MF system. By simply sliding the focus ring back and forth between the two positions you can select either the AF or MF focusing position. In manual-focus mode Tamron lenses provide smooth, precise manual focusing by turning their wide, well-textured focusing rings.
