New opera 16-28mm f/2.8 FF Lens for Canon EF Wide Angle

FEATURES:

Advanced AF and One-touch Focus Clutch – The new 16-28mm F2.8 FF is designed for a great user experience and to give photographers the confidence to create beautiful images. The lens includes a newly designed Silent Drive module using new GMR magnetic auto-focus (AF) sensors for faster, smoother, and quieter AF than the previous generation. Additionally, the directional rotation of the focus ring matches the direction of proprietary Nikon and Canon lenses.

The One-Touch Focus Clutch Mechanism makes switching from AF to manual focus (MF) simple. While in AF mode the user only needs to snap the focus ring back toward the camera to engage “real” manual focus control. This gives the photographers an authentic tactile MF feel with hard stops on either side of the focus range like traditional manual lenses.

Advanced Optical Design – The lens incorporates a complex optical design, with 15 elements in 13 groups. Using 3 aspherical lenses including a large aspherical P-MO element and 3 all-glass molded Low-Dispersion (SD) elements, the lens effectively suppresses chromatic and spherical aberrations. The large front element provides super-low distortion and low light fall-off for straight lines and minimal exposure vignetting. Perfect for architectural, landscape, and astro photographers.
