To preface, I must clarify that I am not primarily a photographer or a dedicated Canon user. While I do own two Canon cameras (a GX7 and an M50), my main experience is shooting video for work on a different system (Lumix and Blackmagic).
Given that I'm not a photographer, my usual environment involves cinema cameras and hybrid mirrorless systems.
However, my partner is a model, and I occasionally check the EXIF data on her photos when she receives them. To my surprise, I've noticed that 99% of the photographers use Canon, and 99% of those shoot with an EOS 5D MkIII or MkIV. Actually I can't even remember an instance where it WASN'T one of those two cameras.
My question is: Why are these "older" DSLRs so prevalent instead of Canon's newer mirrorless models? Is there something specific about these DSLRs that makes them more suitable for fashion and lifestyle portraiture?
Some of these are high-budget shoots, so I don't think the camera budget is a limiting factor.
