The new M.ZUIKO DIGITAL ED 100-400mm F5.0-6.3 IS II from OM SYSTEM combines a lot of focal length in a relatively compact body. In addition to the Sync-IS (up to 7 EV), there is an improved tripod collar and a fluoride element, which makes cleaning and drying the lens easier - definitely pleasant when you are out and about in rough conditions. But how important are these improvements in practice? For whom can I recommend this lens?
