Repairing the Canon EF 35-80mm f/4-5.6, DIY style

While waiting for the replacement gear for the 18-55mm, I thought I’d post a complete teardown and rebuild of the first-generation Canon EF 35-80mm f/4-5.6:

WARNING: By viewing and/or following this guide, you accept full responsibility for any malfunctions or damage that may be caused to your lens in the course of any service you may attempt to perform on it. Following this guide will void your warranty.

Note that though this video covers the original v1 lens, the II and III models contain virtually identical internal designs and disassemble in nearly the same fashion, short of the front element being retained by three screws on the circumference of the barrel.
