Yes I was thinking that way as well. But during my early research (watching YouTube video) one account suggest me with the extension tube setup, and somehow I just go with it. Luckily it was still useable even after I switch to another camera brand after the old one broke down.
I need to save up some money so that I will be able to buy the dedicated macro lens, I also want to try the focus bracketing feature of this olympus lens.
