Concept: "Three dimensional structural"
An innovation model.
Instead of thick design as our usual, we pursued the design of the thinnest frame shape with acetate. Through huge trial-and-errors, the structure was created. The structure reminds people the railway bridge. Each beam supports each other, so RF-100 are very sturdy. Its lens shape is more classical. Thus, RF-100 could provide the people more classical and cooler impression in spite of the innovation structure.
