We've had the Sony A7r mirrorless camera for almost a year now and have made the decision to definately dump Nikon for these fabulous cameras. We have been with Nikon for well over 20 years and they have been great cameras but unfortunately they (and Canon) have not kept up with current trends in technology and in our view have been overtaken by Sony. As a result we have just put our order in for the Sony A7 Mark 2 which although is not as many Megapixels as our A7r, should be a great travel photography camera. You can check it out at http://www.sony.com.au/product/ilce-7m2
