Tamron 17-70mm F/2.8 Di III-A VC RXD Lens (B070S) (Sony E)
The Tamron 17-70mm f/2.8 Di III-A VC RDX is a 25.5-105mm-equivalent lens for APS-C-format Sony E-mount mirrorless cameras. The wide to the short-tele range is ideal for everyday shooting and the fast f/2.8 constant maximum aperture suits working in difficult lighting conditions and offers improved control over depth of field. Complementing this design is a series of specialized optics, including aspherical and low dispersion elements, that produce well-corrected imagery with high sharpness, clarity, and color accuracy. Also benefitting handling, an RXD stepping motor enables quick, near-silent autofocus performance along with full-time manual focus override and a minimum focusing distance of 7.5". Suiting this lens's use in inclement weather conditions, it also features a moisture-resistant construction along with a fluorine-coated front element to protect against fingerprints and smudging. Bright constant f/2.8 maximum aperture affords consistent brightness throughout the zoom range a
