Hello. I bought this lens new in March 2025 from B&H Photo for $419. I ended up switching to a full-frame camera in December, and I haven't used this lens since. In the 8 or 9 months I owned it, I only used it maybe 5-6 times. It is in EXCELLENT condition, has barely been used. and I have all of the original packaging and papers. This is a great, lightweight lens that takes amazing photos and is incredible in low light. By the way, I am also selling the 16mm and 23mm from this same series - check out my other auctions. This item is being sold WITH NO RESERVE, so this is your chance to get a great deal! Happy bidding. 


Key Features

A fast, versatile prime, this 30mm f/1.4 DC DN Contemporary Lens from Sigma is designed for use with APS-C-format Sony E-mount mirrorless cameras. The bright f/1.4 maximum aperture benefits working in low-light conditions and also affords extensive control over depth of field for using selective focus techniques. The optical design features a pair of aspherical elements, along with one high-refractive index element, which significantly reduces spherical aberrations and distortion for increased clarity and definition for notably sharp image quality. Also, a Super Multi-Layer Coating has been applied to control lens flare and ghosting in strong lighting conditions. Additionally, benefitting both stills shooting and video recording, this compact prime also incorporates a stepping AF motor for smooth, near-silent autofocus performance. A rubber sealing at the lens mount helps protect against dust and other elements entering the lens or camera.

  • As part of the Contemporary line within Sigma's Global Vision series, this lens is designed to achieve a balance between convenience and performance, and meshes a compact, lightweight build and versatile handling with notable optical attributes.
  • Normal-length prime is designed for APS-C-format Sony E-mount mirrorless cameras and provides a 45mm equivalent focal length.
  • Bright f/1.4 maximum aperture excels in low-light conditions and also affords increased control over depth of field for achieving selective focus effects.
  • Two aspherical elements and one high-refractive index element are used to limit distortion and spherical aberrations and also contribute to greater overall sharpness and accurate rendering.
  • A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.
  • A stepping AF motor benefits both photographers and videographers with its fast, precise, and near-silent performance.
  • Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.
  • Constructed using a Thermally Stable Composite (TSC) material for greater precision and use in wide temperature variations. Additionally, a brass bayonet affords improved mounting accuracy and rigidity.
