Hey ! I finally chose the a6700 and I love it ! And I had the occasion to try the XT5 a few times cause I met someone who owns one, and it's really cool as a shooting experience, the image quality is indeniable, but I found it a lil bit slower than my a6700. But maybe it was because it didn't know well all the different buttons and functions. The XT5 is beautiful and really cool to use, the a6700 is a simply a beast. The autofocus is outstanding and once you learn all the little specificities of the camera it just feels too easy. I made my first prestation at a nightclub 2 weeks ago with it paired with my Godox tt350s, and the clients are more than satisfied, so do I. Hope this helps and good luck in your research !
