The Sony Vario-Tessar T* E 16-70mm f/4 SEL1670Z ZA OSS Lens is a mid-range zoom lens that provides a 35mm-equivalent focal length range of 24-105mm, covering wide-angle to short telephoto perspectives. A constant f/4 maximum aperture offers consistent performance throughout the zoom range and is especially beneficial when working with greater zoom magnifications in low-light conditions. Also benefitting working in dim light or at the long end of the zoom range is Optical SteadyShot image stabilization, which serves to minimize the appearance of camera shake by up to four shutter speed steps. Includes the leatherette lens bag, original box and original documentation, a lens cap and lens hood. *Please don't contact me expecting ££ off, the price is not negotiable. It's a brand new lens trending at £650 in other places, I'm not in a hurry to sell and would rather keep it than lose loads on it.
