Shooting Sports with the Sigma 150-600mm

[Rob Bye]

Rob is it true that the tripod collar does not come off the 150-600 sigma?

Bill, I had to go and take a look at my lens - I had never previously tried to remove the collar. It is, indeed, permanently mounted. As you rotate the collar, you can feel a nice detent every 90 degrees. I suppose that mechanism (probably just a spring loaded ball bearing) requires that the collar be fixed in place.
