I have a Sigma 50mm f1.4 that I have been using on my E5. Now that I have switched to m4/3 I still want to use the Sigma (gorgeous bokeh). There is a procedure for adjusting the E5 so a lens will focus very accurately. It involves the use of a focus/alignment target. Currently, I use a Panasonic adapter and I must focus manually as the focus is off. Does anyone know if this adjustment can be done with the E-M5?
