The Yongnuo FE 85mm f/1.8 DF DSM has been out for a while, but DXO just published a review of the lense and it is super sharp. You can read the full review here or check out the summary below:
…the Yongnuo YN 85mm F1.8 S DF DSM get excellent sharpness at the center of the frame but will have to make some compromises, especially in terms of corner softness and chromatic aberrations. Build quality and materials are also not quite on the same level as the comparison lenses from Sony and Zeiss but essentially the Yongnuo offers a high level of quality at a fraction of the price of its competitors…
