Light Lens Lab announced the development of a new 50mm f/1.5 S21 lens (see the original lens listed on eBay for over $14k). LLL plans to produce more S21-styled lenses in the future with different focal lengths:
As we develop optical excellence, we will continue our interest in vintage and legendary optics. Thus, we proudly announce our development of the 50mm f/1.5 “S21”.
Our initial theoretical statistics and performance show excellent results. The MTF chart displays a performance similar to the original MTF. Our aim is to continue developing our lens to have an image circle to cover 44x33mm sensors and improve render performance and dispersion statistics while retaining the classic rendering character of the famous “S21” lenses.
After completing 50mm f/1.5 "S21", with our continued interest in "S21" style optical performance, we will also begin to plan other focal lengths based on the optical performance and characteristics of the 50mm f/1.5 "S21" for both photography and cinema purposes.
