Bought it for 5 500kr, and for the money I think it is very affordable.
Using it on a Canon 70D. Have noticed that it has some chromatic aberration at the aperture of f / 1.4-2.0, but this is also the Canon 50mm f / 1.2. The focus is not always where it should be, but when it is so razor-sharp lens. The weight and size is also a plus in my opinion, because it neither makes the camera front or tail heavy.

- Miss the focus sometimes
Good optically. Very nicely built. Few 50mm that match this. Why so bad then? Well autofocus is imprecise, which is completely unforgivable when it has such a short depth of field. One moment bakfokuserar the second framfokuserar. Are you prepared to focus manually, so it is a lens that delivers. Are not you so choose something else.
Works great for my 5D, looks almost no chromatic aberration or color shifts.
Is very heavy and difficult to move around with.
