Sigma 28-45mm F1.8 DG DN Lens for L-Mount - Full Frame Zoom

Experience the flexibility of a zoom lens with the light-gathering power of a fast prime. The Sigma 28-45mm F1.8 DG DN delivers a constant f/1.8 aperture across the entire 28-45mm range, letting you shoot in low light and create creamy bokeh without swapping lenses. Designed for full-frame L-Mount cameras, this lens offers optical performance that rivals dedicated prime lenses. Sharpness, contrast and color fidelity remain consistent from the wide-angle 28mm end to the short telephoto 45mm, giving you professional-grade images in every frame. The inner zoom mechanism provides smooth, silent operation, perfect for video work or discreet shooting. Combined with Sigma's high-response Linear Actuator (LA) focus motor, autofocus is fast, accurate, and virtually noiseless, so you never miss a decisive moment. Sigma engineered the optical formula to minimize focus breathing, ensuring that perspective stays stable during focus pulls-an essential feature for filmmakers and portrait shooters alike. The result is a versatile, high-performance lens that adapts to creative demands.
