First negative review of the M. Zuiko 60/2.8 Macro

Low light focus - I think there's something wrong with technique or his system. This is so different to my experience I had to go and test it. Even in light that requires a 5" exposure at ISO200, f2.8, the 60mm was still nailing targets first go. I wonder if he's trying to do contrast autofocus on featureless areas or something.

Focus by wire is "not optimal" for macro work. - Pffft. Practice. I'd also like to point out that

"If you have AF enabled (I tend to use S-AF + MF), and you accidentally let your finger off the shutter, you can potentially kiss your finely tuned and focused frame goodbye as you watch the lens rack in and out to try and reestablish focus."

applies to most lenses, whether focus by wire or mechanically linked, like the 12-60. Does anyone have any examples of AF lenses with a mechanical focus that the camera will not try and fight against, or just override, when the shutter button is repressed?

Resolution seems to deteriorate more at high ISO more than it does with some other lenses. - I think I'd need to see an explanation as to how that's supposed to work.
