Four glass elements in three groups help to maintain image quality and a rear gelatin drop-in filter holder is also incorporated into the seamless design.

- Four elements in three groups design helps to maintain the original image quality.
- With the conversion lens in place, the minimum focusing distance is lengthened to 11.6" and the maximum magnification ratio is 1:3.6.
