Believe it or not , you don ' t need to quote yourself 3 times to be heard . I get your point . Play the game . Enjoy it . If you don ' t , put it down and do something else . <| sep |> I have used both Sigma 70200 apo dg hsm os or whatever the name is and previous version , I think it was apo macro something ii . Older nonos has zoom ring close to mount , os one has it near front element . It took less than 5 minutes to get used to it edit I ' ve used older a lot , and the new one for just a while . It really wasn ' t a problem . Using Sigma 2470 was harder zoom is counterclockwise , as it was entirely different from every other lens that I ' ve used , and it look like 10 minutes to get used to . I doubt that will be a problem for you .
