Two ED glass elements and two aspherical elements for superior image quality Extra-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: 27–375mm

Although similar to the SAL18200 in zoom range and performance, the SAL18250 offers a bit more “reach” at the long end that can make a significant difference if you’re shooting sports or wildlife, for example. The tradeoff is a small increase in weight and size, but if you need the extra range the difference is worth it.You get the same outstanding clarity and contrast from the wide 18mm end to full 250mm telephoto, making this lens one of the most useful and versatile for APS-C format cameras and an extremely wide spectrum of subjects.

* The SAL2875 received the

2010 TIPA Best Expert Lens award.

If you use a 35mm full frame format camera body, this award-winning* lens offers an ideal balance of brightness, zoom range and image quality for a wide range of situations you’re likely to encounter in everyday shooting.The fact that it features a constant, bright F2.8 maximum aperture at all focal lengths offers significant advantages for hand held and low light shooting, as well as for creating gorgeous defocused backgrounds. But you never know when you might need to go a bit longer, so if there’s room in your bag consider taking the 75–300mm SAL75300 along as well: the SAL2875 plus SAL75300 combination gives you a full-frame focal length range from
