So, I see that we have new focus squares on the Rabbit Lasers. Two, in fact - one marked “39mm” and one marked “41mm”. Clearly there is some next-level work going on. I see that the 39mm is the same as the previous (unlabled) ones. What is the purpose of using 41mm, other than the obvious outcome of getting a “different” focus?
I’m also thinking that the 39mm square should say “Normal focus” or “Sharpest Focus” on it.
