I am still getting to grips with My Sigma 50-500mm on an E520, but def getting better so will try the EC-14 on it when we get some better light.
My friend is using a G1 with a Pany 70-300 and getting some cracking shots, i think that lens outperforms my oly 70-300. She is yet to try the Bigma on it.
