Inside the lens are different types of glass elements arranged in special groups. It has 5 Special Low Dispersion glass elements and 3 aspherical elements which banish chromatic aberrations and optical distortions respectively.

High Speed AF + HLA

With lightning speed, this lens can quickly and accurately focus on your desired subject. Capturing sports or wild animals has never been easier! Additionally, the lens’s built-in High-Response Linear Actuator helps the 28-45mm F1.8 Art Lens do its thing smoothly and quietly, particularly useful when you don’t want to hear it move around while filming.

Practical Build and Premium Weight

Unlike other zoom lenses that change length when you zoom in or out, this lens stays the same all throughout. Such a detail makes the lens easier to handle and less likely to lose focus. Even with its high-quality parts and build, it’s not too heavy. In fact, it weighs less than one kilogram!

Aperture Ring with Click Switch and Ring Lock Switch

The Sigma 28-45mm F1.8 Art Lens offers both a click switch and a ring lock switch which gives photographers more control and confidence in adjusting exposure settings.
