This month I will be going to Japan for scenic tour with shopping at Tokyo. Looking at my 2x E-M10 & lenses (I also just bought Pany 12-32 pancake), what would you recommend? Since it will be snowing and often I'm outdoor, should I bring 2 bodies to avoid changing lenses? I would foresee taking a lot of landscapes and food photography, day & night. However, overall weight may be a concern since this is a holiday vacation for me and my wife.
