Product Description

The Sigma APO Teleconverter 1.4x EX DG for Nikon F is a high-quality optical accessory designed to extend the reach of compatible Nikon F-mount lenses while maintaining strong overall image performance. By multiplying the focal length by 1.4x, it allows photographers to achieve greater telephoto reach without the need for an additional dedicated lens, making it ideal for wildlife, sports, and distant subject photography. Its apochromatic (APO) optical design helps reduce chromatic aberrations and maintain sharpness, ensuring improved clarity and color accuracy even at extended focal lengths.

Built with Sigma’s EX DG multi-coated optics, the teleconverter helps minimize flare and ghosting while preserving contrast and detail. It is designed to maintain autofocus functionality and EXIF data transmission when used with compatible lenses and camera bodies, providing a seamless shooting experience. The durable all-metal construction ensures reliability in the field, and its careful optical engineering helps minimize image quality loss, making it a practical and effective tool for extending the capabilities of Nikon F-mount telephoto systems.
