I had a Kenko 2X convertor many years ago. Having tried 3 or 4 times with 50mm f1.7. The image quality of photo taken with that convertor was downgraded to unacceptable level. I decided to leave it alone. I bought a Mutar II 2 years ago. I always bring it along with me now. It works very well together with my 85 f1.4 and 70-210 f3.5. It explains the difference. So don't save the bit money and destroy the Zeiss quality. Otherwise, why Zeiss ?
