I had E-M5 for long time and got E-M5 mk II this year. Since last months old E-M5 sit as backup camera not longer leaving home. Recently I got offer to swap E-M5 to E-PL7. Is it worth to make such deal? Keep in mind I use E-M5 mk II as main camera now. Cons: can't share batteries. Pros: E-PL7 is lighter and have good chances to fit small bag for daily use.
