Gemini Auto 2X Tele-Converter Lens w/M/MD Minolta Mount

The Gemini Auto 2X Tele-Converter is an optical accessory designed for Minolta SR/MD/MC-mount 35mm film SLR cameras and lenses. Positioned between the camera body and a primary lens, it doubles the effective focal length of the attached lens (e.g., turning a 130mm lens into a 260mm lens or a 200mm lens into a 400mm lens). Featuring auto-aperture indexing and mechanical diaphragm coupling, it provides an affordable, lightweight solution to double telephoto reach without carrying larger primary telephoto lenses.

Key Features and Specifications

* Minolta MD/MC Mount: Compatible with classic Minolta manual-focus film SLRs (such as the SRT, XE, and X-700 series) and easily adapted to modern mirrorless systems via an MD/MC adapter.
* 2X Magnification: Multiplies the effective focal length of the primary lens by 2x (reduces maximum aperture speed by 2 full stops).
* Automatic Aperture Coupling: Preserves auto-diaphragm linkage and exposure metering functionality with compatible Minolta MD/MC lenses.
* Compact & Lightweight: Adds telephoto magnification while adding minimal weight and bulk to a camera bag.
* Versatile Adapting: Suitable for use with vintage primes and zooms on mirrorless camera bodies using standard MD/MC mount adapters.
