rafael,
I noticed it is sharper and vignettes less on some lenses, but I was stacking TCs on the 200mm & 300mm shots. It really works great on the 400mm f5.6 ais. I own two tc-16s - one unmodified, and one modified. I have been preparing to modify the untouched one, and have been working out a more elegant jumper wire from pin 3 position to the new pin 6 location. I can cut the 112, and 113 solder joints on the NEC CPU easily. The thing I worry most about is all those tiny pins and springs. I need a better tray with a rubberized bottom layer...got off track
However, the very thing I wanted most was a better way to focus my reflex lenses. It works, but needs strong contrast. Next to try it on my 800mm f8 reflex (Rokinon)

Ialso own a unmodified tC16a, for my F4, and a modified one for the D series cameras. You are more courageous than I in attempting this modification.
