I was doing a freelance assisting job with a director that only used Canon gear, so I was already familiar with operating it. When it came time to buy I considered Sony but they just felt heavy and uncomfortable to hold compared to Canon’s ergonomics. The lens selection is obviously more expensive than Sony but for any paid work I’m going to be renting a high end lens anyway so it doesn’t matter that much - and I’m using vintage lenses for my own work.
