I have used both TC's with a number of telephotos (including the F* 300/4.5, but not including the A* 135/1.8 - I usually only use a TC with longer lenses), and I have never noticed any significant difference. The T6-2x is more compact (shorter), but the A 2X-S has those electrical contacts (might be more useful on the newer bodies), so it's pretty much a toss-up for me. Fred
