So i'm kind of wondering if I should rent out Canon lenses from my local photography shop... I would like to, but then again, I'm not so sure because the iris stopped working on my current 50mm f1.8 lens when I attached it to the letus. I'm afraid that if I rent out all of these Canon lenses, the f-stop is going to stop working on all of them after I use them, and then I'm left with "You broke our lenses, the f-stop doesn't work on them anymore."

Any thoughts? Has anyone else had the same problem?

Are you using full manual lenses?
The iris wont work on a an AF lens.
