One Super UD element and one UD element offer a significant reduction in chromatic aberrations while four aspherical elements help to minimize distortions throughout the zoom range and provide consistent edge-to-edge sharpness and illumination.

Ideally suited for landscape and architectural photography, this lens covers ultra-wide to wide-angle perspectives and backs up its versatile zoom range with sophisticated optical components and intuitive handling.What's In The BoxCanon EF 11-24mm f/4L USM LensLens Cap for EF 11-24mm f/4L USMLens Dust Cap E (Rear)LP1424 Lens Case for Canon EF 70-300mm f/4-5.6L IS USM Telephoto LensExtra Bundle Items:1 x Canon EF 124mm f/4L USM Lens1 x Padded Carrying Case (Protect Your Gear!)1 x Lens Pouch Sleeve (for Medium Sized Lenses)1 x Lens Pen Cleaner1 x High Quality Dust Blower1 x Lens Cleaning Solution1 x Blower Brush1 x Lens Tissue Paper5 x Cotton Swabs1 x Deluxe 70" Monopod1 x Lens Cap Keeper (Dont Lose your Caps!)1 x MicroFiber Cloth1 x Large Cleaning Bottle for LCD Monitors2 Year Extended Warranty Included (Replaces Manufacturer Warranty)
