Wildlife and bird photography has a reach problem. Subjects do not cooperate with proximity, environments punish heavy equipment, and the focal lengths required to fill a frame with a distant bird in flight push into ranges where cost and weight traditionally become prohibitive. The OM System OM-1 Mark II with the M.Zuiko Digital ED 150-400mm f/4.5 TC1.25x IS PRO solves this problem in a way that nothing else in the market currently replicates.
