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. 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.
