Specification 70-200mm lenses are one of the most sought-after choices in any range of lenses, but full frame f/2.8 models do have the drawback of being big and heavy, as well as expensive.

For portable, versatile optical excellence, look no further than the new EF 70-200mm f/4L IS II USM. It features an improved Optical Image Stabilization system that is designed to deliver up to 5 stops* of correction for clear and stable images, with the new IS Mode 3 added specifically for...

Great build and image quality, especially sharpness and contrast; Light enough to carry around and hand-hold

None I can think of practically

Take one of Canon's most popular lenses, the Canon 70-200mm f/4 L , add an up-to-4-stop Image Stabilizer and you get the Canon EF 70-200mm f/4L IS USM Lens. If you don't need the subject-action-stopping and background-blurring capabilities of the faster Canon EF 70-200 f/2.8L IS Lens , this lens...
