I’m strug­gling to get sharp wildlife shots with my D500 and Sigma 150-600mm Con­tem­po­rary lens. Do you have any tips?

Ja­son says... Your cam­era and lens com­bi­na­tion is cer­tainly ca­pa­ble of very sharp shots, but the ‘ef­fec­tive’ DX fo­cal length of up to 900mm can pose prob­lems. To avoid cam­era shake, aim for a fast shut­ter speed of

atleast 1/1000 sec at the long end of the zoom range. The lens’s op­ti­cal sta­biliser can help, even if you’re us­ing a mono­pod, but you’ll still need fast shut­ter speeds to freeze any mo­tion. If nec­es­sary, in­crease your D500’s ISO set­ting by a suf­fi­cient amount to get the shut­ter speed that you need.

Us­ing a tri­pod is the most ef­fec­tive de­fence against cam­era shake, but even with a tri­pod, if the mo­ment of ex­po­sure isn’t crit­i­cal, try us­ing the cam­era’s ex­po­sure de­lay mode, too; this re­duces any vi­bra­tions caused by mir­ror bounce – a re­ac­tion to the re­flex mir­ror flip­ping up just prior to the shut­ter being re­leased.

When pho­tograph­ing wildlife with long lenses, a faster shut­ter speed is crit­i­cal for sharp shots
