a 55-200mm lens isn't long enough for the photographs I need to to complete a project. Is their any way to get out to 400mm plus focal length still using my Fuji system? Previously I used Canon equipment. The longest lens was a 28-300mm which is also not long enough for what I am am trying to achieve. High quality images are essential to go with the other images already shot with the Fuji X-T1, X Pro-1 and Fuji X series lenses. Any advice would be gratefullt accepted.
