Traveling to Japan and Italy in January. Which Fuji lens do I bring along with my 23 1.4?

Hi friends. In about a month I am looking to do some serious traveling. I am going solo and will be taking a good part of this time photographing. I am currently shooting with a x-pro2 and 23mm 1.4. I am looking to add one more lens to my collection in order to try something new out. Ive been shooting primes only for about 8 years now and would like to play around with a zoom. Any suggestions and why?Thank you ! via /r/photography http://ift.tt/2fYtUFM
