It also features a minimum focusing distance of just 25 centimeters that, combined with 0.34x maximum magnification, will let you get close and explore details. If you want to be prepared for a wider range of subjects the SAL1855 is the perfect companion for the SAL55200-2, the pair providing excellent optical performance from 18mm to 200mm. • Weight (approx): 210 g • Dimensions (Dia. x L): 69.5 x 69 mm • Max. magnification ratio: 0.34x 22 S mode, 1/250 sec., F6.3, +1.0 EV, ISO 3200, Auto white balance; Photo: Shinya Morimoto High magnification zoom DT 18-200mm F3.5-6.3 SAL18200 Two ED glass elements and three aspherical elements for superior image quality Broad zoom range in a compact, lightweight lens Circular aperture for attractive defocusing Internal focusing for fast autofocus and short min. focus distance 35mm equivalent focal length: 27-300mm At 18 mm 100 80 60 40 20 Aspherical lens At 200 mm 100 ED glass 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 It will take you from a wide scene-spanning 18mm to far-reaching 200mm telephoto that will let you zoom in on distant subjects, yet the SAL18200 weighs only 405 grams and is no larger than many zooms of more limited range. For these reasons it is an excellent choice for photographers who want to cover as many situations as possible without having to change lenses. In addition to being an outstanding one-lens solution, it features a refined optical design that ensures excellent sharpness and contrast throughout the image at all focal lengths, so you can shoot with confidence in any situation that arises. • Weight (approx): 405 g • Dimensions (Dia. x L): 73 x 85.5 mm • Max. magnification ratio: 0.27x 23
