Sigma 16-28mm f/2.8 DG DN Contemporary Lens for Sony E Mount - Black

The Sigma 16-28mm f/2.8 DG DN Contemporary Lens for Sony E is a small, lightweight, high-performance ultra wide zoom designed to enhance a photographer's toolkit by offering a flexible range of focal lengths without sacrificing optical quality. Due to its tiny depth of field, a fast f/2.8 constant aperture is particularly helpful for close-up images and enables the use of faster shutter speeds in low-light situations.

For better clarity and color accuracy, this lens uses a sophisticated configuration of specialized aspherical and low dispersion glass elements to successfully reduce chromatic aberrations. While working in bright lighting situations, super multi-layer and nano porous coatings have also been used to enhance contrast and color rendering by lowering lens flare and ghosting. The internal zoom and focus mechanism maintains the lens's size over the entire zoom range and at all focus distances. It is the perfect tool for travel, landscape, and video graphy because of the design element that permits nearly no balance point shift and a fixed front element.

Features:

• A nine-blade rounded diaphragm contributes to the bokeh's smooth and pleasing quality.
• The 72mm front filter thread makes it possible to use standard screw-in filters rather than specialized setups.
• The maximum aperture of constant f/2.8 is ideal for working in the available lighting.
• For improved sharpness and precise rendering, two aspherical elements with large diameters control distortion and spherical aberrations.
• Built to withstand the elements and featuring a brass bayonet for increased mounting rigidity and accuracy
• Photographers and videographers alike benefit from a stepping AF motor's rapid, precise, and nearly silent performance. You can also select manual focus control for the entire time.
