It's no secret that Sony aspires to dominate in the pro sports photography market, and this new stabilized 600mm F4 is about as professional as it gets. It's well-built, fast-to-focus, weather-sealed and lighter than any other 600mm in its class (albeit barely).

While 600mm may not be a focal length we shoot at very often, we definitely walked away impressed after putting it through its paces at a Sony-sponsored event.
