400mm f/2.8 Lens
The super-telephoto 400mm f/2.8 lens captures incredibly crisp images and the new models have shed a lot of weight, which is a great feature for a pro sports lens. Low light performance is exceptional, not to mention the fast focusing speed and precision that its low aperture allows. As a prime lens, it doesn’t have the benefit of zoom but works great in combination with the 70-200mm f/2.8 lens.
The 400mm f/2.8 lens captures spectacular motorsport, birding, wildlife and mid-field rugby photographs. The 600mm f/4 will handle the aviation and cricket sports easier but if you add the 1.4x converter to the 400mm f/2.8 lens, it extends your range to a 560mm f/4.
