Canon EF 200-400mm f/4L IS USM Extender 1.4x Review

Canon EF 200-400mm f/4 IS USM Extender 1.4X review: does the performance justify the price?

 Introduction Although Canon announced the lens’ development in February 2011, subsequently showing a prototype at CP+, Yokohama Japan, working models were first ‘seen’ during the London Olympics in 2012 before being only officially announced recently in May 2013. At $11,800, the lens is unashamedly targeting professionals and well-heeled enthusiasts looking to use it for sports and wildlife.Without the extender in place the new lens achieves a DxOMark score of 24 points, dropping to 17 points with in place which is good for a telephoto-zoom but still behind less extreme models.Tamron SP 70-200mm F/2.8 Di VC USD
