I just bought the sigma one week ago and so far I'm pleased, I'll send it to calibrate anyway(soft at 2.8 and I guess it front focusses a small tad).
I need more reach sometimes and I'm pondering the 1.4 extenders. Is there anyone using the sigma with an extender out there? If so, what are your thoughts?
I will appreciate the input as I really will need it soon.
