I recently traveled with my old EP 2 through Europe. I really enjoyed taking pictures but there was only one problem. The weight of the camera and the lens was enough to cause a slight ache in my shoulders as I carried the Camera around my neck for hours. I have looked at more advanced Olympus cameras but it appears that EM 1 is heavier than my camera. I wonder if it would be better to find some alternate type of straps to carry the camera or may be go with EP 5, which is also a lighter camera.
