I learn something new everyday!

I have to hand it to this forum. It never crossed my mind to stack teleconverters. Today I added a Kenko 7 element 2X TC to my Canon 1.4 on to my 100 to 400 IS.
I thought it wouldn't be very sharp, but the results exceeded my expectations. Comments appreciated. Mark

Wow,
Mark I would not hve thought it could look this good. :shock:

Pretty impressive results :)

Nice work once again Mark . . . you are breaking new ground. Now I will have to try this. Bob is the only other I am aware of that stacks this way. Good work.

Beautiful, that is really something else.

Those are excellent. How far from the birds were you with that setup?

Stan, they were about 50 to 60 feet away. I was using a tripod with ballhead but not tensioned, with the IS on.
