I am going to Italy next week and I want to buy either of these cameras... I can buy the gx1 for about 550 euros and the e-m5 for about 880 euros. I currently have the panasonic 20mm and the panasonic 14-45mm lenses. Do you think that the e-m5 worth the price difference? Which would be better for a beginner? I am looking to be future proof- I don't want to replace the camera anytime soon.
