Going to Honduras for a week. I have the NEX-6 with the following lenses: Sigma 19mm Sony 35mm Sony 55-200mm I'm thinking of getting the Sony 50mm. But perhaps there's a more purposeful combo of lenses to bring to Honduras and I should wait on the 50mm? Also, I've been considering upgrading the NEX-6, a camera I'm somewhat familiar with, to the a6000, which I'm not familiar with. So, which combo of lenses would you recommend? Take the chance that I'll be comfortable with the a6000 and that it'd be worth upgrading prior to the trip? Thanks!
