RRS 80-400 Collar is Saweet!
The Really Right Stuff LC-A13 80-400 repl collar is now available and is a VAST improvement over the stock collar that comes with the lens. The collar operation is smooth as silk, not quite as tall as the stock collar and more importantly, is much beefier than the stock collar. Unlike the stock collar, you remove the RRS collar by unscrewing the knob and than swinging half of the collar over the barrel. Can’t recommend this enough to you!
