Sigma 28-45mm f/1.8 DG DN Art - Sony E, L-Mount

The Sigma 28-45mm f/1.8 DG DN Art is a world-first large-aperture wide-to-standard zoom designed for full-frame mirrorless systems. It offers a constant f/1.8 maximum aperture across the entire range, providing the light-gathering capabilities and depth-of-field control typically reserved for prime lenses. The internal zoom mechanism maintains a constant length, making it a highly capable tool for video work and gimbal use where balance is critical. When inspecting a used copy, ensure the internal zoom and focus movements are smooth and silent, as the HLA (High-response Linear Actuator) motor should be nearly inaudible. SDS checks the weather-sealing gaskets for integrity and ensures the customisable buttons and aperture ring click-switch operate correctly. Check the front element for coating marks, as this is a large piece of glass.
