I bought this lens to compliment my standard 38.1 foucs length lens. I use this for cutting thicker materials because of its longer focus cone. I had to make a new focus tool but that was a simple cut out with my laser. Definitely recommend this lens, will definitely buy again in the future.11/19/2018
