Hey,

yesterday I shot the same picture with a Canon 135mm f/2 + Canon Extender 1.4 II and a Canon 200mm f/2.8 lens.

After downloading the two photos to the computer I was surprised, the picture with the 135mm + Extender was a tiny bit sharper than the one taken with the 200mm f/2.8, and it had less CA!

Is it possible? Anyone tried this before? Thanks for any answer!
