I will explain why the item "long stroke of the focusing ring" is classified as both a plus and a minus. For unhurried, thoughtful shooting or video filming, this is a definite plus. Refocusing is very smooth, accurate. But for reportage, sports or children's photography, focus management will become a very difficult task. Even confirmation of focus in many cases will not save. So keep in mind. Drawing and constructive - that's what most people buy CZ for. And here few people will argue - both parameters are on top.
