On the other hand, that of the SIGMA 150-600mm F5-6.3 DG OS HSM | Contemporary is to achieve a lightweight and compact construction for higher usability with similar specifications. The internal construction minimises optical aberrations throughout the entire focal range, while in-built optical stabilisation allows for sharp, precise images to be captured even in poor light.
Featuring water-resistant coating, an optical stabiliser and a rounded 9-blade diaphragm for pleasing bokeh, the Sigma 150-600mm is a superb all-rounder. With the enhanced AF algorithm, smoother AF is achieved.
KENKO Teleplus Pro 300 DGX converters are made with precision quality multi-coated optical glass supplied by Hoya Corporation, the worlds largest manufacturer of optical glass. These glass elements were designed to match the optical quality of the prime lens (even at the edges) and telephoto zoom lenses. The optical design of the elements and light path is wide enough not to cause vignetting.
