If you were to go on a trip and wanted to carry two cameras with a prime on each instead of one camera and switching lens' which combo would you choose out of my options ?? Oly e-pl2 Oly om-d e-m5 Oly 17 1.8 Oly 45 1.8 My opinion is that the 45mm is better than the 17mm which I believe many agree with. Would you put the better lens on the better camera or even things out and put the 45mm on the epl2 ? Or would it not matter ?
