Teleconverters affect the closest focus distance ?

Pondria said:

When a teleconverter ( 1.4x, 2x ) is installed, I understand that f
and focal length changes by the factor - 14 or 2.0. What about the
closest focus distance ? For instance, the closest focus distance
of 70-200/2.8L is 1.5m. Let's say you put 2x on it. Then, does it
become 140-400/5.6 with still the same closest focus distance of
1.5 m ?

Hi Pondria,

It is like Tom already said, the TC does NOT affect the closest
focus distance.

BTW: It doesn't have to be the Canon TC, the Sigma TC's are performing
quite good too

So, do you have Sigma 2x ? If so, what would you say about it ?

Sigma 50-500.
