The E 30mm f/3.5 Macro Lens from Sony. Designed to work with APS-C-format E-mount cameras, this lens offers a normal-length 45mm equivalent focal length that makes it useful for a wide variety of subjects and its unique macro capabilities mean it's also well-suitable for close focusing on nearby subjects. Internal focusing design helps contribute to fast autofocusing speeds and prevents the lens' overall length from changing during use, helping to keep a consistent working distance when photographing close-up subjects. One extra-low dispersion glass element is featured in the lens design to help reduce chromatic aberrations and color fringing for improved clarity and color neutrality. The rounded seven-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
