You mentioned that you don't do a lot of low-light stuff, so I think you might like the A7Riv. I shoot Nikon and Sony mirrorless and often run into lots of unwanted noise with high-ISO, low light on the Sony. I find myself going back to the Nikon D850 for low-light moving subjects, just because that camera does a great job of auto focusing in dim light. I first went to Sony for small, light-weight, etc., but soon realized that when you attach a quality f2.8 zoom to the camera, your back to a heavy, bulky camera. Have fun. When people tell you, "it's not about the gear" just remember that the "gear" does make some of us REALLY HAPPY.
