I'm pretty sure it's been asked before - once by me even - but the answers were less than conclusive. Does anyone know if you can use the Sigma 150 with a TC - any TC? I'm not asking if you can use it with every one, rather if any one can be used with it. The last time I asked this question, I got two opposing answers. Then someone said that it would work with the Sigma TC's.
The problem is, I've not seen any information supporting the affirmative answers anywhere. What I'm hoping is that someone that owns the lens - and done the tests - could answer.
So if you own the Sigma (and yes, I do - and a Canon 1.4 as well. The TC is loaned out right now, so I can't self-test) and a TC that you've used with it, could you answer? Maybe even post a shot or two? Give a couple remarks on your findings?
Thanks!!
