The Sony SAL-30M28 30mm f/2.8 DT Macro Autofocus Lens is a compact and portable macro lens meant to introduce novice photographers to close-up image-making. Its cost, design, and overall size all lead the tyro to comfortably accessorize their kit lens, and begin developing a library of optics for their camera.
Note! Not compatible with 35mm or "full-frame" digital SLR cameras
30mm lens (45mm equivalent in full/frame 35mm format) is an "everyday" focal length with the benefits of macro-ranged optical properties.
Focusing down to an impressive minimum focusing distance of only 5.1" (13cm) is aided by the inclusion of Sony's Smooth Autofocus Motor (SAM) smoothly driving the lens system.
