It features an extensive 11x zoom range, from wide 18mm to 200mm telephoto with impressive image quality all the way. The advanced Optical SteadyShot image stabilization system included in this lens will not only make it easier to shoot blur-free stills at long focal lengths, but it also has an automatic Active Mode that will help keep your movie images steady as you move around with the camera while shooting at the wide end of the zoom range. Another feature that contributes to high-quality movie production is extremely quiet autofocus and aperture operation that will keep your soundtracks free of unwanted camera noise. • Weight (approx): 524 g • Dimensions (Dia. x L): 75.5 x 99 mm • Max. magnification ratio: 0.35x 60 A mode, 1/20 sec., F5, -0.3EV, ISO 800, Auto white balance Telephoto zoom E 55-210mm F 4.5-6.3 OSS SEL55210 At 55 mm 100 80 60 40 20 Aspherical lens At 210 mm 100 80 60 40 20 0 3 6 9 12 Distance from optical center of lens (mm) 0 3 6 9 12 Distance from optical center of lens (mm) Spatial frequency Max. aperture R T 10 line pairs/mm F8 aperture R T 30 line pairs/mm R: Radial values T: Tangential values Compact, lightweight 3.8x telephoto zoom with high-quality metal exterior Two ED glass elements and two aspherical elements for superior image quality Ideal for shooting stills or movies Internal OSS (Optical SteadyShot™) image stabilization Built-in motor delivers smooth, quiet autofocus and aperture operation Circular aperture for attractive defocusing 35mm equivalent focal length: 82.5mm-315mm An ideal complement to the 18-55mm zoom range of the SEL1855, this 3.8x zoom lens takes you from 55mm out to 210mm with consistently outstanding optical performance all the way. In 35mm full-frame equivalent terms that's a wide zoom range of 82.5mm to 315mm, providing plenty of reach for outdoor sports or nature photography. 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. And if you shoot movies as well as stills, the built in motor contributes to quiet yet responsive autofocus and aperture operation that keep your movie soundtrack free from mechanical noise. • Weight (approx): 330 g • Dimensions (Dia.
