I've used several bags and I find that what makes or breaks my back is the large amount of stuff I cram into them. Though I would add that a sternum strap is essential to me. This keeps you from having to roll your shoulders forward all of the time which greatly changes things if you've never tried it with a heavy load.

There needs to be a common network to connect the phone to the camera and there are two options for this: 1) a normal router/wifi access point that both camera and phone connect to, or 2) the camera is the access point and the phone connects to it. I often forget that my phone is connected to a different access point when I have my camera configured to be the access point.

This is what usually gets me when I turn on the camera and try to connect to it with my phone. Access point is handy when you're in the field and are not already connected to wifi with your phone. Your phone and camera need to be on the same network, so if your phone is already connected to an access point then you need to connect your camera to that same access point or connect your phone to the access point provided by the camera.

Fear not, an edit is imminent :)

I can see how that would be misleading. What I mean is that in a scene that lends itself to low ISO, additional EV probably won't make a lot of difference because cameras already have a lot of DR. But in a scene that requires high ISO, DR is so reduced that additional DR may be more impactful, even if it's not a lot of additional DR.

@MichaelClark I wasn't comparing those cameras specifically, but trying to describe dynamic range generally. As illustrated by the graph in your answer, the camera with inferior dynamic range at low ISO bests the other at high ISO, marking the importance of digging up the details when examining this stat.
