I thought I would share some pictures taken on my vacation last week, all taken with the a6400 and Tamron 17-70 (except the first picture where I used the Sony 10-18). Some pictures may be re-posts if you've seen them in other threads, but all were taken during the same trip.
Thanks man! Its a great lens, but I'm coming to realize its a bit heavy/bulky for your typical travel lens. I think the Sony 18-135 is actually better suited to a vacation lens, especially if you're taking the majority of photos during the day. I've been traveling with the 17-70 & 10-18 in my kit bag, but I may go back to carrying the 10-18, 18-135, and 35 (f1.8) instead... we'll see.
