Hello Everyone,
We are excited to announce that the Light Lens Lab 50mm f/1.5 "Z21" is now in production stage. A prototype has been completed and has arrived in North America for testing. This prototype is also available for reviewers worldwide. After several iterations, the current version has shown excellent results, with its rendering and performance closely resembling that of the original 50mm f/1.5 "S21." Consequently, we are moving forward with the production of the 50mm f/1.5 "Z21."
