45mm Prime Lens for Full Frame Mirrorless

Although 45mm is a standard focal length, the lens from sigma is anything but, with excellent image quality and a super compact form factor that all but guarantees it a spot in your camera bag. The lens is optimised for full-frame mirrorless cameras, especially those with ultra-high-resolution sensors, and can produce razor sharp results.

Bright f/2.8 Aperture

With a bright f/2.8 aperture, the lens can capture more light, especially useful when it’s a little bit darker.

High-Resolution Optics

At the other end of the spectrum, when stopped down the lens is incredibly sharp, making it a perfect match for high-resolution images sensors. The impressive resolution uses 8 glass elements, arranged in 7 groups to deliver sharp results and controls spherical aberrations. The optical design also minimises flare and ghosting to capture images with excellent detail and contrast.

Boasting a classic manual aperture control ring with a satisfying click the lens barrel has an all-metal construction, as does the lens hood. Not only does this add to the ruggedness and robust design of the lens but also highlights the style and class of this excellent lens.
