I have a TCon17 and when I use it on my telephotos like my 135mm, I can feel extra friction in the focus ring.

One question though. How much light do you lose when you use a screw on teleconvertor?

point well taken pete. that's what happens when all you have is manual lenses.. well, i do have the kit lens. altho the tcon is a monster..
