M.Zuiko 60mm Macro very slow focussing ?
Dec 7, 2012

I've received yesterday my new M.Zuiko 60mm F/2,8 Macro lens. Among all the m4/3 lenses that I have, this new lens is by far the lowest one to focus.

For objects under bright or covered sky, no problem. But for indoor shots, especialy for distant objects, the focussing mecanism is very slow.

Moreover, is it really a F/2,8 lens ? Indoor, on evening, when light is quite average (not in a dark room) ISO jumps easily at very hight ISO (4000, 5000 ISO, for exemple), as if I was in a dark lane. Yet aperture is at F/2,8

Could my copy be defective ?
