The Minolta AF II APO teleconverters are frequently found on eBay. They’re quite a bit less expensive than their equivalent Sony models, but you won’t get auto-focusing on any Sony lenses. They aren’t compatible with SSM focusing. They will meter correctly and provide proper EXIF data.
The Minolta AF II APO have updated gearing for high-speed focusing as opposed to the older Minolta AF APO models.
They are both multi-coated and have a predominately amber color.
Compatibility: for the most part, the Minolta AF teleconverter II APO 1.4x is fully compatible withthe Minolta 200mm F/2.8, 200mm F/4 macro, 300mm F/2.8, 300mm F/4, 400mm F/4.5 and 600mm F/4 including all HS-APO G models of each lens. The 2x teleconverter is fully compatible with the Minolta 200mm F/2.8, 300mm F/2.8, including all HS-APO G models of each lens.
Optically, they’re the same as the new Sony models, but without the ability to auto-focus on Sony lenses. If you’re building a Sony DSLR system, do not buy these teleconverters, pay the extra money and get a full functioning 8 pin Minolta APO (D) or Sony. Note: the Sony 135mm F/2.8 STF lens will accept teleconverters, but will not auto-focus by design, and is not an auto-focus lens.
