Sony SEL1617Z 16-70mm F4 zoom lens made by Carl Zeiss, with optical image stabilization. MC protector is also included! - Brand: Sony - Model Name: E 16-70mm F4 ZA OSS - Focal Length: 16-70mm - Maximum Aperture: F4 - Lens Construction: Carl Zeiss - Accessories: Original box, instruction manual, lens hood, lens cap This lens is attractive with its wide 16-70mm focal length and a constant F4 aperture. I found it very useful to have just this lens when traveling and wanting to minimize luggage. There is some minor dirt (see photo 6), but there are no operational issues. A protector has been attached since purchase, so there are no scratches on the lens.
