Really, I would like to buy the xf 55-200mm Len, but I can't justify the cost, especially when I consider how often it will make an outing. So I'm hoping to acheive similar with an adapted lens. Does anyone have a suggestion of something that works well. I used to own an olympus om 55-200mm f4 lens which was a cracker of a lens.. Anyone tried this, or have a similar suggestion? Thanks, Sean.
