If your intention is to take travel photos I recommend you to buy a camera it's far better than smartphone but if you need a mobile I suggest you to buy Sony Xperia 1 it's recently lunched smartphone with the feature of led oled display and triple camera with wide angle and telephoto which help you to zoom and get great depth of field and it's also have a Sony senser so you probably get sharp images. buy this one if your budget is above 70k
Samsung s9+ is good otherwise if not mobile costly mobile then u can buy an action camera sj cam series or any in the range of 10k it will be good for travelling photography and videography
