I think this might be the world's only 1.6x lens, mods from a 2x lens. No focusing necessary over 3m and least distortion. Sorry, I am unable to upload photos here. But following download links should work.

Isn't that a sankor 16F?

 

​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.

​Very interesting. Why do you say it cannot be used regularly? in your first post you said "No focusing necessary over 3m". Does that mean you can focus with your taking lens?

​Regularly use is only focusing from 0.5~1m.  I need to add different dioptres to make it focusing correctly.  But I will keep this secret now.  :D

Yes, focusing on taking lens.  I realized that, when the lens is in quite wide angle, or less ratio on anamorphic lens.  Focusing is not critical.  That is why many 1.33x or 1.5x lens can be used as fixed focus.  And also I learn any anamorphic lens, if make front glass and rear glass closer, the ratio will decrease, and the angle will be able to be wider.  So I don't need low ratio anamorphic lens too, sold my 1.5x and 1.33x lenses.
