Sigma 28-70mm F2.8 DG DN Contemporary - Sony E arrives as a versatile standard zoom designed for modern mirrorless cameras, offering a bright constant f/2.8 aperture in a compact, travel-friendly package.

This lens is built for MILC (mirrorless interchangeable-lens cameras) and mounts on the Sony E system, making it an ideal partner for Sony mirrorless bodies seeking a flexible everyday zoom.

Optically the zoom employs a sophisticated 16 elements in 12 groups construction to deliver sharp images across the 28–70mm focal length range while maintaining controlled aberrations and pleasing rendering.

With a constant minimum aperture of f/2.8 and a 9‑blade diaphragm, the lens excels in low-light situations and produces a smooth, rounded bokeh that flatters portraits and subject isolation.

Its compact dimensions — 103.5 mm length, 7.22 cm diameter and a weight of approx. 470 g — make it comfortable for long shoots and travel.

Designed without optical image stabilization, it benefits from Sony in-body stabilization on compatible bodies. Practical accessories include a lens hood, bag and lens cap, and the front accepts 67 mm filters for protection and creative filters.

Use cases span travel, street, event and portrait photography where a bright, lightweight zoom simplifies kit and speeds up shooting. The Sigma 28-70mm F2.8 DG DN Contemporary is a strong choice for photographers who want f/2.8 performance in a compact Sony E mount package.
