The second-hand E-M5 my girlfriend bought doesn't seem to work like mine. I've adjusted my E-M5's (Custom menu -->) "Slow Limit" when needed and it has always worked like a charm (e.g. when I set it to 1/40 the camera raises ISO only when the exposure would exceed 1/40s). The (not-so) funny thing is that my girlfriend's camera doesn't work like that at all. I select Auto-ISO and set the Slow Limit to 1/60 --> When I shoot in a poorly lit environment the camera keeps the max. shutter time at 1/125 and raises the ISO without ever adjusting the shutter to 1/100, 1/80 or 1/60. Both cameras should have pretty much the same settings (e.g. Auto-ISO low limit 200 and high limit 2000 and Slow Limit 1/60) yet they don't function the same way. Both cameras have the same firmware (2.0). I've only tested the camera with my Oly60mm but I can't imagine the lens would make any difference - after all the 60mm has always worked identically with my other lenses on my own cameras. Any ideas why the slow limit doesn't work as it should? PS. I just tried to set the Slow Limit to 1/200s, 1/160s and 1/100s. The first two worked as they should but the 1/100s option raised ISO at 1/125s instead of the selected 1/100s.
