Tamron 17-70mm F/2.8 Di III-A VC RXD
Photographers who own Sony E-mount APS-C mirrorless cameras should seriously consider the Tamron 17-70mm F/2.8 Di III-A VC RXD (Model B070) lens. It’s a terrific all-around zoom lens that’s relatively compact – 4.7 inches in length; 18.5 ounces in weight – and relatively affordable – $799. I tested the Tamron 17-70mm F/2.8 Di III with the A6600, which is Sony’s premium E-mount APS-C camera, and found it be a killer combo for a variety of shooting situations. The 17-70mm is Tamron’s first fast aperture zoom lens for mirrorless cameras with APS-C sensors and I appreciated the constant maximum aperture of f/2.8 across the entire 4.1x zoom range, which is equivalent to 25.5-105mm on a full frame camera. Tamron’s reliable VC (Vibration Compensation) optical image stabilizer helped reduce camera shake when capturing still photos while added AI (artificial intelligence) technology helped stabilize footage when shooting video. The Tamron 17-70mm F/2.8 Di III-A VC RXD features 16 elements in 12 groups and there are two GM (Glass Molded Aspherical) lens elements and one hybrid aspherical lens element. That’s a pretty impressive set for a zoom lens with a constant f/2.8 aperture that retails for under $800. The best things about the Tamron 17-70mm though are its portability and its versatility. I put it on the A6600 and didn’t take it off for weeks, capturing everything from landscapes to covered bridges to zoomed in shots of wildlife. My images were sharp, while the fast f/2.8 aperture was great in low light and created beautiful bokeh.
