Please give me some recommendations on what teleconverters will
work with the Tamron 70-200mm 2.8. I am asking for a friend who
is starting to research them. Thanks!!!

First, you need to provide a camera mount. Second, do you want a 1.4X or 2X teleconverter. A Tamron teleconverter should be compatible. And there are other options such as third party teleconverters. Good luck.

His best bet is to get the 1.4X. You will get more degradation using a 2.0X. The Canon "L" lenses and Nikon Gold Ring lenses are exceptions though. Very slight degradation using teleconverters. Tamron makes quality lenses, but aren't comparable to the above mentioned lenses. Almost? I have an interest in the Tamron 70-200 f2.8 G2.

I attended a Canon Learning Center short lecture on Canon EOS lenses and flashes yesterday. The presenter was pretty forthright and strongly suggested use of a 1.4x rather than the 2.0x with the Canon 70-200 and 100-400 "L" lenses especially if you're expecting/want AF.

I tried a 3rd party 1.4 teleconverter a year ago and it would not auto focus on any of my lenses including a tamron 70-200 f/2.8 and a tamron 24-70 f/2.8. I sent it back and checked tamrons teleconverters but they only mentioned they were designed for older film lenses.

A few months ago I bought a nikon 1.4 tele which was advertised to only work on certain nikon lenses. It worked fine on my nikon lens but it has a special mount with a special notch so won't even attach to tamrons.
