Designed to rival the primes, this zoom's optics have been revamped to provide even greater resolution, clarity, and bokeh quality.
- Bright f/2.8 constant aperture allows users to capture images in dim lighting conditions and with a shallow depth of field.
- One Super ED (extra-low dispersion) and Two ED elements effectively suppress chromatic aberrations and color fringing for greater clarity and color fidelity.
- Five aspherical elements, including three extreme aspherical elements (XA), minimize spherical aberrations, distortion, and also reduce 'onion ring' bokeh.
