Collector Notes:

While not as sharp as matched converters from Sony or Minolta, the Teleplus MC4 offers solid performance on lenses like the Minolta 200mm f/2.8 APO, Sony 70–200mm f/2.8 G, or Tamron 90mm f/2.8 Macro. Autofocus may hunt on slower lenses, and manual focus is recommended for apertures narrower than f/5.6. Not recommended for wide-angle zooms below 50mm due to optical vignetting.
