World's First Full-Frame, F1.8 Zoom Lens

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.

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.
