The Pentax FA 43mm f/1.8 Limited is one of the two best lens I have ever used. It was designed to be the perfect normal focal length on 35mm film (AKA "full frame"). It's an unusual focal length on Pentax APS-C digital cameras, and works out to 86mm equivalent on Olympus MFT... which is a perfect portrait focal length! Besides the incredible handling, this lens is small and has a nice custom screw-on hood. More important, it renders unlike any other I have had the pleasure of using, except perhaps for its sister, the FA 77mm Limited. The look is neutral, without overt bokeh effects or anything of the like. But it provides a lovely volumetric rendering, with plenty of fine detail. I don't use it as often as I might on Olympus, since I have several other lenses in this focal range and the length of the required adapter is a bit off-putting. For that reason I never though to post here, until I realised no-one else had accounted for this lens. That's rather unbelievable for a lens this superior. As an aside, Pentax made a version of this lens for Leica, the only time they ever ventured into a different mount! I have tons of shots on Pentax DSLR using this lens, if you want to check out Flickr.
