I would like to take my first steps into the world of macro photography and would like to know if it is possible to do this with my current lenses. My lenses are the Olympus Pro 12-40 and Pro 40-150 F2.8 + Olympus 45mm f1.8. The most obvious choice is, of course, the Olympus 60mm f2.8 macro lens, but I do not want to scare the insects by being too close with my lens, I thought maybe a beter en cheaper way is to use to the Olympus 40-150 with some extension tubes? Now I see on the Internet various types and brands of extension tubes. The question here is, of course, which are the best suited for me?
