Sigma Art 28-45mm f/1.8 DG DN
Delivering a constant f/1.8 aperture across its 28-45mm zoom range, this lens eliminates the need for multiple fast primes in a kit. Its robust, weather-sealed build and de-clickable aperture ring make it equally suited for hybrid video work, while the HLA motor provides fast, quiet autofocus. This lens is best for event photographers and gimbal operators who need prime-level light gathering in a single, flexible zoom.
