Can a Tele Converter replace an expensive Super Tele? Vivitar MC Tele Converter 2X-22

Cost: free, came with a lens (average market price $8)

Can a cheap Tele Converter with a sharp lens replace an expensive Super Tele? The answer is "Hell No!" But I had to try...

I used the Tele Convertor with a sharp lens I tested before, the Tau/Five Star 200mm 1:4.5 MC. The results were lacking in contrast, not sharp at all, and a lot of chromatic aberration. On top, you loose a full stop, so I had to shoot in much higher ISO and there was hardly enough sharpness, light and contrast for the Peak Focus feature to work. So lot's of pictures that were out of focus.

In all fairness, results might be better with a higher end Tele Converter with more elements... I will not be using this one again...
