Great option!

I find the muscle memory of using these premarked rings is incredibly helpful in my work as a commercial focus puller. This way, on different sets of lenses I still work with essentially the same throw, so there's less time on the job where I need to learn the lens. Highly recommend.
Great for muscle memory

The pre-marked rings for the WCU-4 are great for internalizing the muscle memory of what it feels like to pull from distance A to distance B, regardless of the throw on different lenses.
