I have spent most of the last decade searching for the best possible technology to make the ObscuraFlex focusing screen. It's a balancing act between brightness, sharpness, clarity, color purity, vignette reduction, focus accuracy, cost effectiveness, and finally... practicality and simplicity of manufacture.
In June 2025 I discovered a new technology that may be the holy grail of focusing screens for use with ObscuraFlex adapters.
Below are detail sections of three test exposures, on the left is a traditional ground glass screen, in the middle is the best ObscuraFlex screen I have been able to make until now... on the right is the new 2025 technology that I hope will be a marked improvement for every user.
The bottom row shows a section of screen approximately 1/4inch square. You can clearly see the improved clarity, detail, and evenness of exposure.
This new screen will be replacing the old screen for all new sales as soon as I can stabilize the supply chain. Hopefully by the end of July 2025. Existing customers will be contacted with a discount "upgrade" code if they choose to replace their existing screen. If you have an older screen and haven't heard from me, please reach out via the contact page.
