i have read about the olympus 9-18 and it sounds very good but the olympus 75-300mm that i need more mainly for my wildlife stuff is an expensive lens for me, the pana 100-300 is not as expensive but i far prefer a range like my Tamrons 28-300mm,selling my current lenses wont bring in much,if the new adaptor would work on my GH2 could solve the problem but i have doubts and can see me selling my canon fit lenses for a small amount to get new micro four third lenses.

I see Martyn. You had mentioned the Zuiko, didn't know about the Tamron. le'ts hope something comes out.
