Not compatible with 35mm or "full-frame" digital SLR cameras
The 18-250mm f/3.5-6.3 DT Alpha A-Mount Wide-Telephoto Lens from Sony is great for nearly any situation, with focal lengths ranging from 18-250mm on cropped APS-C size cameras, with the 35mm equivalent of a long 27-375mm zoom. As it is a DT-series Sony lens, it has been optimized for these smaller image sensors, and is not recommended for use with larger 35mm full-frame cameras.
This lens is constructed of 16 elements in 13 groups, as well as 3x Extra-low Dispersion (ED) glass elements, which all help to deliver sharp, clear photos throughout the zoom range. It has a minimum focusing distance of 1.5' and a front-end filter diameter of 62mm.
Its aperture varies depending on the focal length you choose, and will slowly increase from f/3.5 to f/6.3, or f/22 to 40, as the chosen focal length increases. It also has an internal focusing system, zoom lock to prevent it from extending when you don't want it to, and 7x circular aperture blades that work to produce smooth, out of focus background effects.
Note! Not compatible with 35mm or "full-frame" digital SLR cameras.
