Rent NowThe Sony DT 18-55mm f/3.5-5.6 is a compact standard zoom for Sony A-mount cameras with APS-C sensors. It covers a 27-82.5mm equivalent focal range, from wide-angle to short telephoto. That makes it a practical everyday lens for travel, family photos, landscapes, interiors, street shooting and casual portraits. It’s small and light, so the camera stays easy to carry for long stretches.
The DT designation means the lens is optimized for APS-C sensors. That lets it stay compact while matching the smaller image circle of Sony’s crop-sensor Alpha DSLR and SLT bodies. On full-frame A-mount cameras, it’s meant to be used in APS-C crop mode.
The optical design uses 8 elements in 7 groups to give clean, consistent image quality across the zoom range. A 7-blade circular diaphragm gives a smooth, natural background blur when you shoot toward the longer end or focus on nearby subjects. The aperture ranges from f/3.5-5.6 at its widest to f/22-36 at its smallest, giving you enough control for most everyday shooting.
Autofocus is driven by Sony’s SAM (Smooth Autofocus Motor), which sits inside the lens. That gives smooth, quiet focusing that suits both stills and casual video. An AF/MF switch on the barrel lets you change to manual focus when you want full control.
Close focusing is one of this lens’s strengths. Minimum focus distance is just 0.25m (9.8″) throughout the zoom range, with a maximum magnification of 0.34x. That makes it useful for flowers, food, products and small details. The lens takes 55mm filters.
