<p>What teleconverter have you used with a 400 5.6 prime in an FD mount? I picked up a Vivitar 400 mm 5.6 FD mount lens and am now looking to extend its reach with a teleconverter. According to this site: <a href="http://bit.ly/2dzu400">http://bit.ly/2dzu400</a> Canon made a FD 2X-A that may be compatible? I'm looking for any suggestions that may work, I'm aware of the loss of light and quality issues. Just want to see what your experience was.</p>
