The world's first 17-70mm F2.8, large aperture standard zoom lens for APS-C mirrorless cameras
The 17-70mm F/2.8 Di III-A VC RXD (Model B070) is a large aperture everyday zoom lens for Sony E-mount APS-C and Fujifilm-X mirrorless cameras. This lens was created to achieve a broad zoom range and excellent image quality. With a focal length range of 17-70mm (a full-frame equivalent of 25.5-105mm), it’s the world's first F2.8 standard zoom lens with a 4.1x zoom ratio for APS-C cameras. The 17-70mm includes Tamron's proprietary VC (Vibration Compensation). Additionally, this lens focuses very close. It features an MOD (Minimum Object Distance) of 0.19m (7.5 in) at the wide-angle end and 0.39m (15.4 in) at the telephoto end. When shooting very close to the subject, the lens enables expressive imagery with highly blurred backgrounds, a feature unique to large aperture lenses. From portrait to landscape, and your everyday life, this lens captures all of the excitement and discoveries with the finest possible detail.
Features and Functions

VC for worry-free still photography and video capture
The 17-70mm F2.8 utilizes Tamron's highly regarded, proprietary VC image stabilization to maximize the inherent optical performance of the lens. It reduces the degradation of picture quality caused by minute camera shake that is likely to occur during handheld shooting at slow shutter speeds under low-light conditions indoors or at dusk. When shooting video, by leveraging AI technology, image stabilization performance improves compared to conventional models.

Superb AF keeps it sharp and quiet
The AF drive incorporates an RXD (Rapid eXtra-silent stepping Drive) stepping motor unit. RXD uses an actuator that is able to precisely control the rotational angle of the motor, allowing it to drive the focusing lens without passing through a reduction gear.The addition of a sensor that detects the position of the lens to a high degree of accuracy enables high-speed and precise AF, which allows you to maintain razorsharp focus when shooting continually moving subjects or filming video. The lens is also remarkably quiet, eliminating concerns of drive sounds being picked up while shooting video

Built with Mirrorless in Mind
Tamron’s new 17-70mm F2.8 zoom is compatible with many of the advanced features that are specific to mirrorless cameras. This includes:
Fast Hybrid AF
Eye AF
Direct Manual Focus (DMF)
In-camera lens correction (shading, chromatic aberration, distortion)
Camera-based lens unit firmware updates
Additional product features
- ASL
ASL
Asfærisk linse - Asfæriske linser korrigerer sfæriske afvigelser (fokusfejl) i zoomobjektiver. De kan erstatte flere andre optiske elementer uden tab af kvalitet, hvilket bidrager til et mere kompakt objektivdesign.
- VC
VC (vibrationskompensation)
Vibrationskompensation - TAMRON-udviklet billedstabilisering, der kompenserer for uønskede kamerabevægelser og giver skarpere billeder. Lukkertider på op til 5 EV-stop langsommere er mulige med VC-billedstabilisatoren.
- FLR
FLR
Fluorbelægning - Fluorbelægning beskytter frontlinsen mod forurening. Det forhindrer olie- og vanddråber i at sætte sig fast på overfladen. Fingeraftryk og snavs er lettere at fjerne.
- IF
System til intern fokusering (IF)
Intern fokusering - Intern fokusering forhindrer, at tønden forlænges og roterer under fokuseringen. Objektivet er lettere at håndtere og er velegnet til brug med polarisations- eller gradueringsfiltre.
- LD
LD (lav spredning)
Low Dispersion - LD-elementer har et særligt lavt farvespredningsindeks. De reducerer kromatiske aberrationer, der viser sig som farveskær på kontrastkanterne og reducerer billedskarpheden.
- XLD
XLD-glas (ekstra lav spredning)
Extra-Low Dispersion - XLD-elementer har et særligt lavt farvespredningsindeks. De reducerer kromatiske aberrationer, der viser sig som farveskær på kontrastkanterne og reducerer billedskarpheden.
- MR
MR
Fugtbestandig konstruktion - Linsen er modstandsdygtig over for stænk. Alle kritiske områder har særlige tætninger. Linser med denne funktion er ideelle til udendørs brug i dårligt vejr.
- RXD
RXD (Rapid eXtra lydløst drev)
Rapid Extra-Silent Drive - RXD-autofokus er meget responsiv, hvilket gør den ideel til optagelse af stillbilleder og video af motiver i bevægelse. En sensor registrerer konstant den aktuelle fokusindstilling, så den kontinuerlige autofokus (AF-C) lynhurtigt kan ramme den nødvendige rotationsvinkel for at fokusere.
