This lens is definitely a keeper...But be warned, there are two versions of this lens, AVOID the NEW motorized version, it will definitely give you headaches more than you could ever imagine
(ie. Intermittent focusing problems, soft images,slower focus vs.the old version IRONICALLY etc.) I had a chance to compare these two versions at a shop in Belgium but the OLD non-motor Japan version has won me over,...My only slight complaint is the shitty noise...but then again, I got used to it
