Deitz Premium 1.7X N/AF teleconverter lens adapter

The Deitz Premium 1.7X N/AF is a teleconverter lens adapter designed for SLR and DSLR cameras, likely produced in the late 1990s to early 2000s. This optical accessory increases the focal length of the primary lens by 1.7 times while maintaining relatively close focus capabilities, though it reduces the maximum aperture by approximately 1.5 stops. Teleconverters like the Deitz Premium were popular among photography enthusiasts who wanted to extend their telephoto reach without investing in expensive long lenses. These adapters are particularly valued by wildlife, sports, and nature photographers who need additional magnification in situations where physically moving closer to the subject isn't possible. The 'N/AF' designation indicates it was designed for Nikon autofocus systems.
