    I recently saw a Zuiko 300mm f2.8 sell on Ebay for $3,200. That is almost getting to the point where I might be able to get one past the Minister of Finance. My only concern is speed of autofocus on the EM-1. Can anyone comment on how fast this lens focuses as compared to say the 50-200?

    Also, how well does it work with the 2x TC?
