Extreme Lens Geekery now! Lens Rentals decided to do a triple-header teardown of the three 24-70mm f2.8 lenses from Canon, Nikon and Tamron. Lots of pictures and lens body parts! Do not try this at home unless you know what you are doing and do not object to ruining these expensive lenses. See the completed teardown at the Lens Rentals blog.
