Fascinating. I would have thought the Canon 24-70mm would have had more percentage of use with the 5D II and III. If you're interested in those cameras (or many of the cameras and lenses listed in this post) you should check out KitSplit, a company I co-founded.

KitSplit is a marketplace for cameras and related equipment. If you rent equipment, you can search on KitSplit across hundreds of owners including individual filmmakers and artists, rental houses, and production companies and studios. You can find the best option; book and pay online, often saving up to 30% compared to traditional options; and get delivery and insurance...all while supporting other filmmakers and small businesses.

And if you own your own gear, consider listing it on the site so you can make money renting it when you're not using it. We make it easy and safe for you by listing your gear, handling the logistics, vetting every member, and ensuring that your gear is always fully insured. Check us out at www.kitsplit.com

Great list! There's also a comprehensive guide from KitSplit that includes several grants for VR tech, docs, narrative and more:
