Sigma APO Teleconverter 1.4X EX DG for Nikon F &nbsptype_Instant Colour 5-stop neutral density filter designedThe Sigma APO Teleconverter 1. 4X EX DG for Nikon F mount is a good quality, compact teleconverter for use with many (but not all!) Sigma F mount zoom lenses. It may also work with other brands, but we can't guarantee it. Please check your lens instruction manual for compatibility: this is not a universal teleconverter and it won't work with everything. In excellent condition, with clean glass and good function. Includes softcase.
