>>3796388For macro 60mm is fantastic. It's one of the lenses that catches your eyes and you just go into the system for it, it's just so good. But it has some really annoying usability problems.
Since you already have 60mm, maybe get Panaleica instead. You can also try and get Raynox 250 and try it on Sigma, or your other lenses first. In any way, it fits well on 60mm Oly to get higher than 1:1 magnification. Just know that you need 46mm to 43mm step down ring to use it on Olympus. Universal adapter that comes with raynox is good for 52-67mm threads.
60mm fits well on Olympus bodies, body stabilization makes it perfectly usable handheld in most situation. Know that you will get only get in cam focus bracketing with it on Olympus bodies. Same goes for Panaleica on Panasonic bodies. It's dumb thing that Pana and Olympus do to encourage sales of own lenses. It's still perfectly usable on Pana bodies that have ibis. 60mm has almost perfect corner sharpness even at f2.8, at time it needs to be closed to around f4 to really get rid of ca, and is usable up to f16. At f22, diffraction becomes a problem. It's pointy, and looks big on the body, but it is a very light lens. Perfect 2nd body while outing, you barely notice the added weight.
Negatives. Auto focus speed is abysmal, no matter the body. It can also hunt for focus on weaker bodies. It's better on pdaf cams, but still easily the worst of all my lenses for the system. It doesn't matter that much on macro, since you're mostly in MF, but it can still be annoying. You get a switch on the lens that lets you select focusing distance that helps with focusing, but it's not a perfect solution. MF ring is focus by wire, and not a good iteration of it either. On top of this, it's really battery hungry. One extra battery is almost a must on every extended macro outing with it. And it's also a bit flimsy. I banged mine, and had to have it repaired.
