What this lens is good for
Bird and wildlife photography
A 600mm full-frame equivalent prime at f/4 with built-in stabilisation, the benchmark birding lens for the system. It is sharp, weather sealed, and pairs with the MC-14 and MC-20 teleconverters for even more reach at a modest aperture penalty. At 1,270g it is a manageable handheld super-telephoto. Full guide →
Sports and distant detail
