In most cases the best camera you can use is the one you have, in this case, my iPhone. I hate it, well, hate is a strong word... when someone sees a shot of mine and they say, "hey, nice shot, what camera do you use? Ummm, who cares what kind of camera, it's about the operator not the camera. If you understand how to use the gear you have you will be amazed at the quality of work you can get from it. Don't get me wrong, I love my Sony Mirrorless a7riii but I don't carry it with me all of the time.
sometimes I just want a snapshot without the concern of camera settings, plus, my family gets tired of that too.
These are just some random, un edited shots that I took. My better half and two of my chillens at a wedding in Houston, somewhere along the Blue Ridge Pkwy, Three puppies that we literally rescued and our Blue ridge GA farm at sunrise... simply because I had the camera in my pocket. Don't let the gear get in the way, just keep creating!
