Is the canon ef 600mm f 4l is iii usm good for sports?

Honestly, it's a strong lens for sport, but only from the right spot. The Canon EF 600mm f/4L IS III USM is a 600mm prime with stabilisation and autofocus, and it's excellent at long range. But it's very heavy and very expensive. For sideline sport and larger animals, the site's advice is to start around 70-200mm to 100-400mm on full frame. The 600mm is better suited to birds and distant action, where you can't get closer.

If you do want it for sport, these bodies are on its fit list:

• Canon EOS-1D X Mark III: full frame, the most serious option here.
• Canon EOS 5D Mark IV: full frame, a more affordable way in.
• Canon EOS 7D Mark II: APS-C, which adds even more reach.
