I have always used back button focussing on my DSLR. Far better control over af.
In reply to an earlier question, the Sigma lenses span the quality range. Some aren't very good, some are exceptionally good.
Until recently I had a Sigma 150-600 Sport which was used primarily for aviation photography. It was a heavy beast but I was happy with the results.
All the attached were taken with that lens.
