Originally produced as Konica Minolta AF Zoom DT 18-200mm f/3.5-6.3 (D) by Konica Minolta in 2005, and currently produced by Sony, the Sony α DT 18-200mm f/3.5-6.3 (SAL-18200) is compatible with cameras using the Minolta A-mount and Sony A-mount lens mounts. The DT designation means this lens is designed to be used with a camera with an APS-C size sensor. When the 1.5× crop factor is considered, the lens has an effective equivalent 27–300mm focal length. The lens is derived from the Tamron AF 18-200mm f/3.5-6.3 XR Di II LD Aspherical [IF] (models A14M/A14S).

Zoom creep is a phenomenon in zoom lenses where the angle of view of the lens changes when gravity is allowed to freely act on it. If the lens has a zoom ring, holding it when the lens is held upwards or downwards will prevent this change. In lenses with push-pull zoom, creep is prevented by holding the extending part of the lens. Some lenses, such as the Tamron SP AF 17-50mm f/2.8 XR Di II LD Aspherical [IF] and Canon EF-S 18-135mm f/3.5-5.6 IS STM, have a zoom lock to stop the effect.
