Again, isn't dating and renting equivalent?

Regardless, it is outdated when very few owned film cameras. If you had a chance to buy a set of Cooke lenses for a steal even though you didn't own a camera, you absolutely would if you were able. You could then rent a Red, Arri, or even film cameras as needed. You're forcing this into a modern digital only situation where camera bodies are dirt cheap maybe from being younger so that's your familiarity??
