Are you sure that tc will go on the 80-400VR?????
I use the kenlo pro 300 1.4 on that lens
When I ordered it from B&H they said that was the only one to use on that lens.
Might do some checking
1.4 will give you 600
GaleDo you see the little icon (8th) (yellow with a little mountain in it)one from the left in the message reply box
you click on that , it ill bring up a box at the top of your screen and you paste your URL in there and put a (.) dot..like below
.jpg at the end of your url
You need a hosting service like smugmug, pbase or several others available out there
Some are free some are a low pay.
Ok the t.c may fit but will the camera and lens reconize the communications between them.
For you I hope so:>)))
