Okay, I am rigging my a6500 for an outdoor wildlife video. I will be shooting off of a tripod. Due to my being farsighted, it is hard for me to use monitors, especially in outdoor daylight conditions. The problem is, I want to rig my camera up with a cage, mic, monitor, and external battery. But these make it impossible to use the built-in viewfinder. What I want is a viewfinder that I can extend out behind the camera. I have searched around but can't seem to find what I a looking for. Can anyone here point me in the right direction?
