hi, its a quick question really. I've got the Pana leica DG 25mm on my E-PM1, now when i'm in the SCP in the IBIS settings it says focal lenth 50mm... i assumed that this is in 35mm equivilant or should i change this value to 24? although this quote from the olympus support page has me confused. "Do not take into account the 2x magnification factor applied in the Four Thirds system; enter the actual focal length of the lens being used. If the attached lens has a focal length that is not shown on the chart, please select the closest value. The focal length setting cannot be entered manually when a Four Thirds or Micro Four Thirds system lens is attached."
