Fuji Fujinon 50mm F/1.4 Lens (M42 fit) in fair condition.

Focus and aperture work as they should and the glass is clear with a few tiny dust particles. There are some coating loss marks on the front element. I have not noticed these affect any pictures.

This version of the Fuji 50mm F/1.4 has the most lovely bokeh of all of them in my opinion. It is sharp enough to use wide open and throws the background into "painting" softness, with just enough texture to be really interesting. It is great with flowers wide open, giving a sharp central flower with georgeous softness to surrounding foliage. Specular highlights (especially those from shiny leaves) are rendered beautifully. Please note that this lens does not have neutral bokeh like modern lenses, it has real character.

Of all the 50mm F/1.4's I have (and I have a lot of them!) this has the best bokeh.

This is a full frame lens. It can be used with focal reducers on crop sensors (e.g. Micro 4/3) to give 37mm F/1.0.
