i used to have one, then sold it, when the diafragm became slow. it is optically excellent, has some (not much) color fringing in the corners, very sharp in the center. mechaniclally very good. well worth the $100 or so that i paid. very big and quite heavy (it's f/2.5, not 2.8!) as far as filters go, they cannot be used with MX and ME-Super. LX is fine. but the filters DO NOT HAVE TO BE USED there, unlike many other lenses with rear filters, those are not mandatory on this particular lens.
