There's still seats available in my Chile Total Solar Eclipse and Croatia Waterfalls and Culture workshops.

Tripod Collars, one fixed!


by Brent Bergherm

In this video I take a look at various tripod collars AND I fix an annoying issue with my Sigma 120-300 f/2.8 sports.

A while ago I had a client mention that the Sigma lens would grind as he rotated it from vertical to horizontal positions using the tripod collar. So I researched the issue and I fixed it. Take a look to learn more about your lens’ tripod collar design.

The screws purchased to fix the 120-300. Removed the screw heads and cut to length with a dremel too.

The ball bearings used for this fix on the Sigma 120-300.

The replacement tripod collar has gone up in price since I fixed this lens!
