Define "professional camera". Im a "professional photographer", meaning that is my only job and has been for 15 years. Ive used my XS Max and 11 Pro Max on a few natural light portrait photoshoots with nice results. Ive even used it in studio with a ring light. Is it going to replace my full frame Canon mirrorless and excellent lenses? No. Can it be used as a tool alongside my camera in certain situations? Absolutely. I look forward to using my new 12 Pro Max a bit on a shoot or two next week.
