EF 400mm f/4 DO IS USM

The EF 400mm f/4 DO IS USM features a multilayer diffractive optical lens technology that makes the lens small and lightweight yet optically superb quality. Built-in image stabilization feature offers up to two stops of image correction. The lens has a fast max aperture of f/4 making it ideal for fast action, sports and wildlife photography.

Canon’s breakthrough multi-layer diffractive optical lens technology provides photographers with superior super-telephoto performance in a smaller and lighter design with enhanced correction for chromatic aberrations. We’ve also added our highly effective Image Stabilization system that gives the equivalent effect of a shutter speed two stops faster. And, it’s built to our professional standards with fast AF, full-time mechanical focus and dust and water-resistant construction.

    Comments about Canon 400 mm EF f/4 DO IS USM Zoom Lens:

    I use this product for taking photos mostly of wildlife and sport close-ups. This lens is the best zoom lens i have ever had in my life and i will never get board with using it. There is nothing wrong with this lens.
