DT 18–55mm F3.5–5.6 SAM SAL1855
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.

DT 18–135mm F3.5–5.6 SAM SAL18135
Developed to provide the most ideal focal range for normal use—
covering frequently-used focal lengths between 18mm and 135mm—
the Sony SAL18135 mid-range zoom lens enables rich expression for a
wide range of shots. Direct Manual Focus (DMF) allows you to switch
between AF and MF without removing your eyes from the viewfinder
to seize fleeting photo ops with ease. Plus, enjoy smooth and quiet AF
thanks to the Smooth Autofocus Motor (SAM), which also improves AF
response when shooting moving subjects. And with a single ED glass
lens element as well as a pair of Aspherical lens elements, the SAL18135
delivers images with low levels of color aberration for excellent image
quality in any setting.
