Vivitar 2× Macro Focusing Teleconverter + Albinar 2× Macro Pentax K Japan

Enhance your macro photography with this Vivitar 2× Macro Focusing Teleconverter paired with an Albinar-ADG 2× Macro Converter, both for the Pentax K (PK) mount. These manual-focus teleconverters are ideal for 35mm SLR and adapted digital workflows, providing 2× magnification and the ability to achieve 1:1 macro focus when used with compatible lenses. Optics on both units are clean with only normal internal dust and no fungus, and the mounts lock smoothly with correct bayonet alignment. Cosmetically they show light handling wear and are both marked Made in Japan, consistent with high-quality 1980s third-party construction. Typical optical design is a 7-element / 4-group layout. Together they weigh approximately 1 lb 4 oz, making them easy to pack for field macro work. A great set for photographers seeking affordable, high-magnification close-up performance on Pentax K-mount systems.
