SIGMA 28-105mm F2.8 DG DN Art Lens with Durable Construction and High-Speed Autofocus (L-Mount)

Description

The SIGMA 28 to 105mm F2.8 DG DN Art Lens for L-Mount is notjust another standard zoom lens. With a powerful wide-angle to medium telephotofocal length and a bright F2.8 aperture throughout, this full-frame mirrorlesszoom combines outstanding optical performance, superb build quality and a rangeof pro-grade features to make it one of the most versatile optics on the marketfor mirrorless systems. The lens is built to tackle a huge range of subjectsand situations, from expansive low-light landscapes to portraits with big,beautiful bokeh, and thanks to SIGMAs latest optical technology and the use oflarge diameter elements including FLD, SLD and five aspherical elements, it isable to do so with superb clarity and sharpness. This allows the lens todeliver exceptional versatility without compromising on optical quality. Thelens also includes high-speed AF with HLA technology, a rugged dust- andsplash-resistant structure, and various functions such as an aperture ring, allpacked into a compact and lightweight body weighing less than 2.2 lbs, makingit an exceptional all-round choice for both stills and video.
Constant F2.8 Aperture across a Versatile 28 to 105mm Zoom
Many conventional zoom lenses which have a reach up to 105mm do not offer aconstant F2.8 aperture, usually dropping to F4 at the long end. But the SIGMA28 to 105mm F2.8 DG DN Art delivers the same impressive light-gathering anddepth-of-field benefits across the whole focal range. The lens offers all ofthis along with extremely high optical performance thanks to the thoroughsuppression of optical aberrations within each lens group. And with itsoutstanding close-focusing capability when zoomed in, macro-style results arealso possible.
Versatile F2.8 Aperture Perfect for Portraits and Low Light
With its fast aperture across the whole focal range, the SIGMA 28 to 105mm F2.8DG DN Art is a true workhorse lens that can be used for almost any type ofphotography. Scenic photographers can shoot wide-angle landscapes, using theF2.8 aperture for low-light scenes and twilight urban views, while the middlefocal lengths tackle dimly lit documentary and street subjects, allowingshutter speeds one stop faster than comparable lenses. At the long end, popularportrait focal lengths from 85mm and 105mm, combined with the F2.8 maximumaperture, produce a shallow depth-of-field that will isolate a subjectimpressively against large and beautiful bokeh.
Fill the Frame with Superb Close-Up Performance
Achieving a minimum focus distance of just 40cm across its entire zoom range, theSIGMA 28 to 105mm F2.8 DG DN Art can get you closer to your subject, fillingthe frame with detail and texture. At its 105mm setting, this creates a veryuseful maximum magnification ratio of 1:3.1 for powerful macro-style results.
Superior Optical Performance across the Full Zoom and Focus Range
The SIGMA 28 to 105mm F2.8 DG DN Art operates without compromise, suppressingaberrations very effectively within each lens group, and throughout the entirezoom and focal range. This ensures the lens has a consistent performance evenwith such a long zoom range. This is thanks to the lenss premium opticaldesign, which includes two FLD, one SLD and five aspherical elements, the firstgrouping of which uses a large-diameter phi 66.4mm element that is extremelydifficult to produce and only available thanks to SIGMAs advancedmanufacturing technology at its sole production base in Aizu, Japan.
Designed to Minimize Flare and Ghosting
Using advanced simulation technology, flare and ghosting have been largelyeliminated, ensuring that the lens renders rich, high-contrast results in allconditions. In addition, SIGMAs Nano Porous Coating and Super Multi-Layer Coatinghave been applied to further suppress flare and ghosting.
