The rights to give integrated optical image stabilizer, up to four stops of shutter speed advantage. Super Spectra coatings control ghosting and flare due to internal reflections.
Polycarbonate is used as the main construction materials in the body of the lens to minimize weight at low cost. Canon claims only environmentally friendly lead-free glass is used in the construction of the lens – but makes no mention of possible plastic components (the cost and weight down, can not maintain visual quality).
