Question about Canon 100mm f/2.8 Macro USM EF Lens
It seems that you have either a faulty lens or one which is performing outside of the minimum quality standards. You have clearly done everything possible to try and eliminate all other causes. Looking at the firmware updates for your camera, none of them mention an issue involving your lens but you may wish to ensure that you have the latest firmware anyway.
All you can do is to contact Canon customer care to request that the lens is exchanged.
