Thank you for viewing. I am selling this item due to disposing of my camera. This is a Leica close-up lens ELPRO E52 SET. It allows for easy macro photography when you are out and about. It comes with 49mm and 46mm step-up rings, and a dedicated case. The instruction manual is not in Japanese. I used it with a Leica Q2. I am not very knowledgeable about lenses, but the person I received it from said that when held up to a light source, there is a slight amount of dust, but it does not affect the photos at all. (I adjusted the focus because the photos were blurry - see the 5th photo) I can't see any dust on the lens in particular, so I'm not sure if there is any. I am selling it because it didn't suit my needs. Due to the high price of this item, I am not accepting returns as a measure against recent product substitution. Thank you for your understanding.
