Sigma’s 135mm f/1.8 ART lens delivers high performance optics in one of the fastest options for a 135mm lens. With a fast f/1.8 aperture it’s outstanding in low-light and provides an nice shallow depth of field.
The lens creates smooth and visually pleasing out of focus elements (or Bokeh), and also uses aspherical elements to minimise aberrations and ensures a crisp, clear image. A Super Multi-Layer coating helps by suppressing flare and ghosting.
Complementing the imaging capabilities, the lens sports a Hyper Sonic Motor to produce quick, smooth, and quiet autofocus performance with full-time manual focus override. The physical design utilises Thermally Stable Composite material for durability in a wide range of environments, and a brass bayonet mount also offers rigidity and mounting precision.
