I am sorry my friend. Let me explain. Let us do some simple calculations. Suppose the distance of the subject from the front of the lens is "a", length of the lens is "b" & the distance from the ...

Er, a bit of nitpicking. Minimum Focusing Distance (MFD), measured from the sensor plane, increases by the length of the TC. Minimum Working Distance (MWD), measured from the front element of the ...

I used an old 1.5x (4 element, non-reporting) version. AF slows down a bit; otherwise it was fine.
