Title
Canon EF 100-300mm F4.5-5.6 USM Teardown
Introduction
This guide will take you through partially disassembling the lens, allowing you to access whichever major part or assembly you need (ex: autofocus assembly, zoom assembly, etc). This guide will not include taking apart the zoom assembly.
A dust blower is recommended to blow dust off of any internal lens elements or parts during this process. Additionally, a clean microfiber cloth is good to have incase you accidentally touch any of the internal lens elements and need to clean off your fingerprint from the lens.
There will be many small screws that must be removed from the lens. Many of the screws will be of different sizes. Please be sure to keep the screws in a safe place and keep track of where each one came from.
