I love the optical performance of the few ZM lenses I've tried especially the 21/4.5 but I have a minor issue with the grip ring at the base of the lens. I find the milled grip to be too fine and flush with the barrel for easy mount/dismount. It seems to me that Leica lenses are easier to grab at the base either because grip ring has a slightly larger diameter than the barrel and/or a coarser shape to the milled ridges. It may also be the tolerances of the bayonet are slightly different making the ZM lenses feel stiffer to mount/dismount on my MP.
