Brand: Sigma

Sigma 30mm f/1.4 DC DN Contemporary for Micro Four Thirds is a bright standard lens designed for modern mirrorless interchangeable-lens cameras, offering a fast f/1.4 aperture for low-light shooting and creative depth of field.

This compact Sigma lens is built for MILC systems and optimised for APS-C image sensors while featuring a Micro Four Thirds (MFT) mount interface for broad compatibility with MFT bodies. Its solid construction includes a 9-element/7-group optical design that balances sharpness and contrast across the frame.

With a diagonal viewing angle of 50.7° and a minimum aperture of f/1.4, the lens delivers strong subject separation and reliable performance in dim conditions. The aperture closes to a maximum of f/16 and uses 9 diaphragm blades to produce pleasing bokeh and smooth out-of-focus highlights.

The Sigma 30mm f/1.4 measures 73.7 mm in length, has a diameter of 6.6 cm, and weighs approximately 263.7 g, making it easy to carry for street, travel, and everyday photography. A removable lens hood is included to reduce flare and protect the front element.

Close-up work is practical with a closest focusing distance of 0.3 m and a maximum magnification of 0.14x, allowing you to capture detail and environmental portraits with attractive background separation. The lens accepts 52 mm filters for added creative control.

Typical use cases include low-light portraiture, street and documentary photography, and general-purpose walkaround use where a fast standard prime improves versatility and image quality. The compact dimensions and lightweight design make it ideal for photographers who prioritise mobility without sacrificing optical performance.

Key selling points are the fast f/1.4 maximum aperture, compact form factor, 9-blade diaphragm for smooth bokeh, and dedicated Micro Four Thirds mount. The lens’s black finish gives a professional look that integrates seamlessly with many camera bodies.
