Manufacturer’s Description

Teleconverters, either 1.4X or 2X, are efficient tools to add focal length to the photographer's arsenal. However, universal-type teleconverters have certain limitations in performance when used with ultra-telephoto lenses of 200mm or longer as compensation of chromatic aberration alone becomes highly critical in this focal length range. The PRO-series teleconverters are specifically designed and optimized for use with such ultra-telephoto lenses to deliver maximum resolution, contrast and color rendition without degrading any aspect of the master lens performance.
