Teleconverters & Lens Mount Adapters ThrustMaster

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 new 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. The 1.4x teleconverter will increase the focal length of the master lens by 1.4x and make the lens one f-stop slower. The 2x
