The Sigma 18-50mm f/2.8 DC DN Contemporary Sony E-Mount is a zoom lens for landscape and portrait photography, for example. This lens is suitable for Sony mirrorless cameras with an APS-C sensor. The zoom range is similar to the 27-75mm lens on a full-frame camera. This lens has a compact size and weighs 290g, so you can easily take it with you for the entire day. The maximum aperture of f/2.8 makes the lens light-sensitive. This allows you to photograph in low-light situations without problems. You can also use the lens to while recording. It has a silent and fast autofocus that you don't hear in your videos. If your full-frame camera has an APS-C crop mode, you can also use this lens.
