It works well enough for some decent photos. If you KNOW you love and want macro photography, then buy a real macro photography lens. If you want to play with macro photography occasionally, or test for a few months to see if you like it - then buy this.
Perfect on the kit lense. Terrible on the 45 prime.
Works extremely well on the 14 42 kit lens. Much better than expected. But seems to have little effect on the 45 mm prime lens, in fact, it seems to degrade the 45 mm image quality. But again is a true wonder on the 14 42 kit lens. Is it a true macro? No.
Works very well on some tiny lenses, to make very compact close-up lenses.
I already had one Olympus MCON-P02, and I discovered one day that, when added to a tiny Panasonic 14mm f2.5 lens, the combination was excellent for close-up shooting (not "macro") since it "peaked" in performance around f18, and it was still very good to f22 (that solved the usual DOF problems with close-up shooting!). I then tried it on my similarly-tiny Panasonic 12-32mm lens, and it was very good on that lens also, giving me a compact "zoom-close-up" lens! So I bought a second MCON-P02 for that one, too. I leave the MCON-P02s on these lenses and use my many other MFT-fit lenses to replace them for normal distance range shooting.

Good quality product that you expect from Olympus. A little more expensive than extension tubes, but a lot easier to use. I am using it on the 45mm F1.8 lens, the digital 2X converter puts you right on your subject. Takes great pictures, but really shallow depth of field. it is virtually worthless on the 17mm F1.8 lens. You really want to use this on something 40mm or higher. If you have a lens like that, buy it and have some fun playing with macro photography! Remember you need 37 or 48 mm filter threads, or you will need to find a filter adapter; they only supply the one.
