No problem with the lens, either my 100-400L or the 100L macro works fine on my T3i's with it, just the 7d mark ii that doesn't like the converter with any lens combo. Glad yours works, what camera are you using with it?
I'm using a Canon 1.4x with a Canon 70-200 2.8L II and a Canon 500F4. v1 To be perfectly honest, it takes a little more time with most shots because autofocus isn't as quick when used without the extender
