No, it is D.O. 16f. I believe they have the same glasses. I can call it's a micro lens, original focus around 0.5~1m, ratio is about 1.6x to 1.75x. Even adjust to infinity, it is still shorter then Sankor's 5ft at minimum distance. This lens is cheap, due to it cannot be used regularly. But IMO, it is worthier than others. So I sold my Sankor and Eiki 16f, which are the same lens. Because it is short, so has the similar angle as 16H. The least distortion is beyond my expectation. Here are a comparison photo.
