Sigma 45mm f/2.8 DG DN Contemporary Lens (Sony E)

A versatile and remarkably compact prime lens, the Sigma 45mm f/2.8 DG Contemporary delivers a practical field of view ideal for everyday photography. Its slightly wider perspective than traditional 50mm lenses makes it exceptionally adaptable across portraits, landscapes, and detailed close-ups.

Complementing the unique field of view is a modest f/2.8 maximum aperture that is bright enough for working in available light conditions yet helps keep the overall lens size and weight down for everyday carry.

• Contemporary Line lens features a compact design that measures approximately 64 x 48mm and a weight of about 235g, making it portable enough for everyday shooting needs without compromising on optics or speed.
• Internal focusing design pairs with a stepping AF motor for responsive and fast focusing performance that's suitable for both stills and video applications.
• Optical design includes two aspherical elements, to optimize sharpness and limit aberrations, and a Super Multi-Layer Coating that controls flare and reflections.
• Rounded 7-blade diaphragm contributes to a smooth and pleasing bokeh quality when employing selective focus techniques.
• Dust and splash-resistant construction with a brass bayonet mount for ensured accuracy and durability.
