The Sigma 1.4X Teleconverter EX APO DG for Canon

The Sigma 1.4x DG EX APO Teleconverter for Canon offers a 1.4x conversion factor with compatible telephoto lenses. When mounted, it reduces aperture speed by one stop. It features an apochromatic lens design through the use of Sigma’s special low-dispersion glass elements, providing images with high color accuracy and minimum optical aberrations. It also has Sigma DG multi-layer coating, which cuts down on ghosting from internal reflections.

PLEASE NOTE: The Sigma 1.4x Teleconverter does not mount to every lens. It has been optimized for performance on certain Sigma lenses.

Roger's Take

A handy little extender. It will vary depending on which lens is used, but in general terms Sigma converters are considered to be nearly as, but not completely as, good as their Canon counterparts.
