Sigma APO Teleconverter 1.4X EX DG for Pentax K

Description

The Sigma APO Teleconverter 1.4X EX DG for Pentax K mount is a good quality, compact teleconverter for use with many (but not all!) Sigma K-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 very good condition, with light finish wear, clean glass, and good function.
