>>4038570Unless you are shooting action at night, the rules and principles of photography are not different depending on sensor size. The only thing you are getting with FF that would help a beginner is some more editing latitude in post… and if you have enough skill to properly edit a photo, then you have enough skill to properly expose a photo.
I’m not telling you to get a MFT camera, but thinking sensor size would help a beginner much, if at all, is off base. If anything, I’d say maybe get a fujifilm camera that has the physical shutter speed and iso dials then force yourself to shoot manual. This will be an intuitive platform to help you learn the exposure triangle.
