all are good choices. I have a Pentax AF 1.7x and an pre APO sigma 1.4x converter

both happily. My complaints about the A* 2.8 300 are that it is too heavy to hand
hold unless
you are a superman, and the tripod mount is 'off balance' unless you have a 10 lb
camera.
The good of the unit for hand holding is that it is internal focusing and you can with
a big enough hand
put
the strong part of your hand under the front for support and reach back with a couple
of fingers
and focus it --- I think I set it on my hand and use the thumb and pinky to focus.
It is a lot harder
to
handle a heavy lense when you have to screw the whole front of the lense.
