Up for sale is an uncommon variant of a rare and exceptional vintage teleconverter, the Vivitar 2x Macro Focusing MC Teleconverter.

This lovely unit, manufactured for Vivitar by Kino Precision (Kiron), not only focuses as a standard, optically-excellent, 2x teleconverter, but it also incorporates a focusing helical that allows for closeup/macro magnifications using standard lenses. With a standard 50mm lens, this unit produces an equivalent 100mm with 1:1 focusing capabilities. On shorter focal length lenses, max magnifications will be even higher, and on longer focal length lenses somewhat lower.

This is the rare Pentax PKA mount variant with aperture pass-through, allowing for full open metering on Pentax A and later film bodies, as well as Pentax DSLRs.

Excellent vintage condition with light handling wear and excellent mechanics. A few markings in rear coatings. Glass free of scratches/haze/fungus.

Includes caps and original leatherette case!
