If you’re the kind of photo enthusiast who likes to carry a camera at all times, whether actively shooting or not, you probably want one small, lightweight lens that won’t be a burden while walking around but will deliver top quality and versatility when a photographic opportunity arises.The SAL1855 is the smallest and lightest zoom in this series, weighing in at only 210 grams while offering an 18–55mm focal length range that will cover most day-to-day subjects. 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.

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.
