CV lenses always have to jump that extra hurdle of lack of snob appeal. Once you get some internet posts of only a couple of dissatisfied users, they unfortunately stick and rumours of softness, bad bokeh, etc., don't disappear. They are amplified and continued by people never having tried a lens they like to criticize.
Good for us 50/2.5, 35/1.4 and 40/1.4 users though, since lenses stay affordable 🙂
