Well, maybe not the devil, but for those of us with a macro lens or two in amongst our lenses, detail is where the fun is.
I now have two macro lenses, the Olympus 60mm f2.8 which doubles as a long portrait lens, and a 12-50mm f2.8 “normal” that has a macro “button.” The lens converts from normal to macro, but it has a mind of its own about what the focus point is. It’s not like any other lens I’ve ever used.
You frame the shot, but unless you have the camera on full manual, it manages the fine focusing. Probably better than I could. Auto-focus is a saving grace for aging eyes.
It will work as a macro throughout its range with the push of a button. Not quite as tight the 60mm, but close enough for the devil.
