Completely understand this liability. I have a couple Tamron's that work well on my camera. Never have been very impressed with Sigma, but this based on hundreds of very positive reviews I've read from multiple sources this NEW 50-150 may be an exception. Though one retaliatory firmware upgrade by Canon could make it worthless. Sadly Canon doesn't have a decent class option for their 1.6x camera's, the zoom range on the L series f2.8 70-200 on a 1.6x camera misses the mark..........and it's twice the $$$.
