Sigma Art 17-40mm f/1.8 DC
A constant f/1.8 aperture across a 17-40mm zoom range delivers exceptional low-light capability and shallow depth of field, backed by an optical design with 4 SLD and 4 aspherical elements for sharpness. Its 25.5-60mm equivalent field of view on APS-C provides a versatile walk-around range, and the bundled filter kit adds immediate practical value. This lens is best for portrait photographers on Sony E-mount APS-C who prioritize subject isolation and handheld shooting in dim conditions.
