As a portrait photographer I shoot in studio most of the time. One of the side benefits of shooting in a controlled environment like a studio is that you can also shoot tethered to your computer. I’ve been shooting tethered into Lightroom Classic CC for years. While every DSLR out there has a USB port (usually on the side) for image transfer, they are rarely designed for having the cable attached 100% of the time. This is to say that when you’re moving around the cable itself can get pulled and stress the port that it’s plugged into. Unfortunately that stress over time can actually break the connection inside the camera resulting in an expensive repair. Back when I was shooting a D700 I had to have it repaired twice. Just recently I had to have my Nikon D810 repaired. That repair was the most expensive to the tune of a few hundred dollars because it involves having to replace the logic board in the camera.
