The Sigma APO Teleconverter 2x EX DG is designed to extend the capabilities of select Sigma Global Vision lenses for Sigma SLR cameras by doubling effective focal length while maintaining a compact and practical form factor. This added reach is valuable for photographers capturing distant subjects such as wildlife, outdoor sports, and action scenes where changing lenses may not be practical. Its optical construction includes Special Low Dispersion glass elements that help reduce chromatic aberration and maintain consistent color accuracy when magnification is increased. When used with compatible camera bodies and lenses, the teleconverter supports autofocus operation up to f/8, allowing continued use of phase-detection systems for precise subject acquisition. Built for real-world shooting environments, the teleconverter features a dust- and splash-resistant design that pairs well with weather-sealed Sigma lenses. Its small size and lightweight build make it easy to integrate into an existing kit without significantly impacting balance or portability. The Sigma APO Teleconverter 2x EX DG is an effective solution for photographers who need additional reach while staying within the Sigma lens ecosystem.Bundle IncludesSigma 2x EX DG APO Teleconverter Cleaning KitLens Cap Keeper
