Albinar-ADG Auto 2x Tele-Converter for Pentax K

The Albinar ADG Auto 2x Tele-Converter is a teleconverter designed for use between compatible lenses and Pentax K-mount SLR camera bodies, increasing the effective focal length of the attached lens by a factor of 2x while reducing the maximum aperture by two stops. The Auto designation indicates electronic or mechanical coupling between the lens and camera body is maintained through the converter, preserving automatic aperture operation with compatible lenses. As a third-party teleconverter from Albinar, it offers an accessible alternative to first-party Pentax teleconverter options at a budget-friendly price point. Autofocus performance and feature compatibility may vary depending on the specific lens and body combination used, and the two-stop aperture reduction should be considered when working in lower light conditions.
