Optically, the binoculars are built with traditional Porro prisms, and an integrated field-flattener lens that corrects spherical aberration for distortion-free views, especially at the edges. Canon's proprietary Super Spectra Coating is used to limit color bias, lens flare and ghosting; while maximizing light transmission, color rendition, clarity, and contrast across the entire visible spectrum. With this new IS system, the close focus distance has been drastically reduced versus earlier models that use a different IS mechanism.
Lens-Shift image stabilization system uses a vibration gyro-mechanism, in conjunction with microprocessors, that detect and counter the appearance of hand-shake by moving the internal lens assembly horizontally and vertically, to make the image appear steady
Powered Image Stabilization is a secondary IS system that improves the image stabilization when focused on a single subject ±1.0° correction angle.
