Wait for the mk 2 to ship and get a good second hand one ?It's the old one, I just want more range.... But I don't want to compromise on quality. I'm abit put off by Sigma, never had much luck with them.

I just want it for wildlife really. I know even the canon is pretty poor in low light.

Interesting video but most of the shots they were showing at the end were from the 500mm f4
