Sigma 24mm f/2 DG DN | Contemporary - Sony E, Leica L Mount

The Sigma 24mm f/2 DG DN Contemporary is a wide-angle prime offering a fast aperture in a relatively small package. Constructed with an all-metal barrel as part of the I-series, it provides excellent tactile feedback through its manual aperture ring and focus switch. The f/2 aperture makes it a strong choice for astrophotography and low-light street photography where a wider field of view is required. Ensure the aperture ring moves freely and the 'Auto' position locks correctly if applicable. Check the front filter thread for any damage, as the metal construction can be prone to denting if dropped. SDS verifies the integrity of the weather-sealing gasket at the mount and confirms that the stepping motor provides smooth, silent focus transitions during video testing.
