Is the sigma 60 600mm f 4 5 6 3 dg os hsm sports good for sports?
Yes, for most sports it's a solid choice. The Sigma 60-600mm f/4.5-6.3 DG OS HSM Sports gives you a wide range, from 60mm for close action to 600mm for distant fields, with stabilisation and autofocus. The catch is that it gets darker as you zoom in, so at 600mm you'll need good high-ISO performance on a dim gym or evening match.
If you shoot mostly at the long end, the heavier, weather-sealed Sigma 150-600mm f/5-6.3 DG OS HSM Sports is worth a look. For a full-frame body with fast readout, the Nikon D6 or Canon EOS-1D X Mark III are both on this lens's list. For more on reach, see wildlife and sport.
