You get better focusing on the 6400 but you lose in body stabilization. If you want to shoot video you have to decide which one is more important to you.Following this thread as I am in the market for a new camera (I'm very inexperienced in camera world) and am intrigued by the new Sony a6400. I was sold on getting the a6500 but when I saw the price difference and what you get with the a6400, it seems to be the way to go. I want to use the camera for backpack hunting while shooting video and taking photos. Now..... which lenses to get? The Sony 18-135mm that comes with the camera seems to be a good starting point? Thoughts?
