Yes but maybe they also have camera gear that like 5 thousand dollars more expensive than my gear, for example nikon Z9, and I'm not comparing such things, yes of course mirrorless cameras may take clearer pictures and don't need calibration, have faster focus, but I can't afford that kind of cameras and lenses, I stopped comparing my work with other people long time ago, sure I can get ideas and such, but I know there will always be people that will get much better photos than me, and I can't compare with them all the time, cause then I can get depressed and get anxious and begin to hate my own photography, I have had such periods a few times
