An ideal complement to the 18-55 mm zoom range of the SEL1855, this 3.8x zoom lens takes you from 55 mm out to 210 mm with consistently outstanding optical performance all the way. Built-in Optical SteadyShot (OSS) image stabilization is a huge advantage when shooting at longer focal lengths or in low light, making it easy to capture crisp, stable images at up to four shutter speeds lower than would normally be possible.
